ABSTRACT:

A review of the Archiceroptera Papp genus complex (Diptera: Sphaeroceridae:

Limosininae)

Steven Mark Paiero

Advisor:

Dr. S.A. Marshall

This thesis has two parts. The first part investigates the relationships between the Archiceroptera genus

complex and other members of the Limosininae (Diptera: Sphaeroceridae). A focus is placed on the

relationships within the larger epandrial process group, which contains Bitheca, Bromeloecia,

Pterogramma, Aptilotella, and Robustagramma, along with Archiceroptera, Rudolfina and several

previously unplaced species groups. Molecular and morphological data sets provide the first phylogeny of

the group, and were used to support the inclusion of several unplaced species groups within Rudolfina and

Archiceroptera, while one new genus is described. Pectinosina gen. nov. includes two species: P.

prominens (Duda), previously placed in Rudolfina, and P. carro n. sp. The second part of the thesis deals

with revisions of Archiceroptera Papp and Rudolfina Roháček. Rudolfina now includes 13 described

species, nine of which are newly described here (R. bucki, R. exuberata, R. howdeni, R. megepandria, R.

pauca, R. pilosa, R. newtoni, R. remiforma, and R. tumida). Archiceroptera now includes 29 species, of

which 27 are newly described here (A. adamas, A. addenda, A. barberi, A. basilia, A. bilobata, A.

bisetosus, A. braziliensis, A. brevivilla, A. browni, A. caliga, A. calligraphia, A. cobolorum, A. crenulata,

A. curvivilla, A. dolabra, A. llama, A. maniba, A. masoni, A. megacercus, A. megavilla, A. mexicorona, A.

mitarakai, A. paracercus, A. pussula, A. ternum, A. triclavus, and A. uncinata).

ACKNOWLEDGEMENTS

My wife, partner and best friend, Jordan, for her support and patience throughout my study, especially the last

gruelling months. - - -

My parents, the rest of my family and many close friends, who supported my passion over the years, along with

bringing me or saving countless insects in vials just in case they were of interest!

To my advisor, Dr. Stephen Marshall, for (most importantly) sharing his passion of entomology in a field course in

1999 that changed the course of my studies, but also for sharing his immense expertise and experience in Diptera.

My committee members, Dr. Gary Umphrey and Dr. Alex Smith, for their input and suggestions during the course

of my study. Access to sequence data extracted from material collected by Dr. Smith, obtained with the support of

various grants, was important for the molecular examination of the broader EPG clade.

The members of my defense committee: Dr. J. Cumming, Dr. J. Fu and Dr. C. Scott-Dupree.

Val Levesque-Beaudin, for helping with the BOLD database and access to barcoded material.

Dr. Matthias Buck, who was the first person to help me appreciate sphaerocerids and many other Diptera families,

during his time at the University of Guelph Insect Collection.

Everyone from the lab, past and present, with special thanks to D. Cheung, M. Jackson, and T. Yau.

I would like to thank the various individuals and institutions that made material available for my study. A. Newton

(FMNH), B. Hubley (ROME), J. Skevington and J. Kits (CNCI), N. Penny (CASC), A. Norrbom (USNM), B.

Brown (Zurqui project material) and M. Pollett (MHNM). It is only through the support of these institutions, along

with their willingness to make material available to other researchers, that these types of studies can succeed. I

would also like to thank A. Brunke (CNCI), Z. Soltes (HMNH) and N. Penny (CASC) for making digital

photographs of type specimens available to me.

This study was funded by an NSERC Discovery Grant awarded to Dr. S. Marshall, and a PGS-D NSERC grant

awarded to myself.

CHAPTER 1 - INTRODUCTION

The Sphaeroceridae is currently divided into six subfamilies, of which the Limosininae is the most diverse

with about 150 described genera and 1650 described species worldwide [based on Marshall et al. 2011 plus

publications since 2011 (see Appendix 1)]. Species of Limosininae can be found on every continent with the

exception of Antarctica and are associated with a variety of decaying organic substances, such as carrion, dung, and

decaying vegetation. Limosinine diversity is highest in the tropics, especially in the Neotropics, and many groups

remain to be adequately studied. One such group is currently treated as the Archiceroptera genus complex (Marshall

and Buck 2010). This complex includes two described genera, Archiceroptera Papp and Rudolfina Roháček, several

unplaced species groups, seven described species (two Archiceroptera, and five Rudolfina) and an estimated 50-90

undescribed species.

The Archiceroptera genus complex belongs to a group of largely Neotropical genera characterized by a

unique finger-like process that extends medially from the right margin of the epandrium (Marshall and Cui 2005,

Luk and Marshall 2014). Species within this epandrial process group all have the following combination of

characters: 3 or more equal interfrontal setae; scutellum with only 2 pairs of setae; cell cup absent; alula narrow with

straight hind margin; mid tibia with at least 1 anterodorsal seta on basal 1/3 (secondarily lost in Aptilotella Duda), 1

anterodorsal seta at midlength, and 1 anterodorsal and 1 posterodorsal seta on apical 3/4; and mid tibia with apical

ventral seta. This combination of characters will separate the "epandrial process" group from almost all other

Limosininae genera with the exception of species that fall into the “boliviensis” group, an unplaced species group in

which males lack an epandrial process. Marshall and Buck (2010) divided the complex into several species groups,

noting that some probably deserve generic rank. These groups are the enigmata group, the brevivilla-group, the

sororcula group (including the discalis group), the addenda group, the ternum-group, the prominens group, and the

exuberata group.

1.1 Biology and Natural History of the Archiceroptera genus complex

Sphaerocerids are associated with a variety of decaying organic material, such as dung, carrion, fruits, and

leaf litter, where the larvae are microbial grazers (Marshall and Richards 1987, Roháček et al. 2001). Members of

the Archiceroptera genus complex have been collected in a wide variety of habitats, mostly using dung and carrion

baits, pan traps, and flight intercept traps, and little is known beyond what can be extrapolated from data labels.

Rudolfina cavernicola Marshall & Fitzgerald is thus far known only from caves in the southwestern United States

(Marshall & Fitzgerald 1997), while R. digitata is associated with high alpine meadows (Marshall 1991).

Not much is known about the behaviour of these or most other Sphaeroceridae, but label data for one

species of the prominens species group provides notes indicating the flies were riding or following dung beetles

(Coleoptera: Scarabaeidae, Scarabaeinae; see discussion for Pectinosina prominens). Kleptoparasitism of scarab

dung balls by sphaerocerids is documented in other genera, and was reviewed by Sivinski et al. (1999), but this

behaviour has not been recorded previously in the Archiceroptera genus complex.

1.2 History of the Archiceroptera genus complex

Papp (1977) described Archiceroptera based on two species: the newly described A. mahunkai Papp and A.

venezolana (Richards), which Papp transferred from Ceroptera. Papp separated Archiceroptera from other

Limosininae on the basis of a single large costagial seta (as found in Ceroptera), unique leg chaetotaxy, and several

small setulae near the basal pair of scutellar setae. Roháček (1982, 1983) transferred Limosina rozkosnyi Roháček to

a new genus, Rudolfia, based on a number of autapomorphic characters (a single enlarged costagial seta, weakly

sclerotized distiphallus, presence of small sclerites below gonopore [phallotrema], epandrium with lateral row of

long setae and strikingly developed cerci, additional small sclerites below gonopore [phallotrema], reduced female

sternite 8, female cerci of unusual “thornlike shape” and fused with the epiproct). Roháček (1987) later renamed

Rudolfia as Rudolfina, as Rudolfia was preoccupied by a copepod crustacean. Since then, two new North American

Rudolfina species have been described (Marshall 1991, Marshall & Fitzgerald 1997) and two species have been

transferred into the genus (Pitkin 1989, Roháček et al. 2001). A chapter in an unpublished thesis by S.A. Marshall

(1982) considered the material available at the time, but was not published because further material, especially from

- 3 -

the Neotropics, was required to clarify generic limits of Rudolfina and Archiceroptera. Marshall and Buck (2010)

summarized ongoing work on the complex, continued by the present author as a doctoral project.

1.3 Relationships with other Limosininae

Marshall and Roháček (1986) considered Rudolfina as a possible outgroup for Trachyopella but it is now

considered that the Archiceroptera genus complex belongs to a larger clade of mostly Neotropical genera diagnosed

by the presence of a small finger-like process that extends from the right side of the epandrium to the hypandrium

(Fig. 1.1; see also Marshall and Cui 2005, Fig. 1), which is considered a synapomorphy for the group. This group

(referred to here as the epandrial process group, or EPG) also includes Robustagramma, Bromeloecia,

Pterogramma, Aptilotella, and Bitheca, but excludes Trachyopella. The relationships between this clade and other

groups within the Limosininae are presently unclear.

1.4 Thesis objectives

The major focus of this thesis was to study the species diversity of the species groups previously included

within the Archiceroptera genus complex and place them in a broader phylogenetic context within the subfamily

Limosininae. The generic limits of Archiceroptera and Rudolfina were both redefined and revised, and their

relationships with each other and related genera were examined using both molecular and morphological character

sets. The remaining species groups of the Archiceroptera genus complex were also placed into a phylogenetic

framework within the broader EPG clade and one new genus was described for a previously described species that

was excluded from Rudolfina and Archiceroptera.

CHAPTER 2 - MATERIALS AND METHODS

Over 8000 specimens of the Archiceroptera genus complex were studied, with the major portion (> 95%)

of that material currently deposited at the University of Guelph Insect Collection, the largest collection of New

World Sphaeroceridae. Some material had already been sorted to the Archiceroptera genus group (“Rudolfina s.l.”)

prior to this study, but another 20+ drawers of unidentified New World Limosininae were also examined for

additional material. Further material came from two inquiries for bulk identifications of Sphaeroceridae. The first

inquiry was from the Zurqui All Diptera Biodiversity Inventory (ZADBI) project, which documented the fly

diversity of a single plot in Costa Rica that was later expanded to include two other sites. Of the ~7000 sphaerocerid

specimens identified to genus or species for this project, only ~20-30 belonged to the Archiceroptera genus complex

but the quality of the specimens allowed sequencing of several species. The other request was from a smaller

collection effort in Mitaraka, French Guiana by Dr. M. Pollet. Approximately 2000 specimens were made available

and provided access to material of previously unknown species along with new distributional data for several other

species.

2.1 Label Information and Distribution Maps

Label data was presented in a consistent manner, not verbatim from the labels; in a few cases obvious spelling errors

were corrected. Shortforms or abbreviations used on the labels were normally interpreted and given in full.

Geographical coordinates were given if present on the original label. Specimens were given unique identifiers and

their collection data was captured within the BIOTA database (Colwell 2012); the specimen data will ultimately be

hosted on the Canadensys website, but unique identifiers were not repeated in the text except for holotypes or for

imaged specimens. Collection data for paratypes and other specimens examined were organized alphabetically by

country, state/province, and locality name. Species distribution maps were generated using SimpleMappr

(Shorthouse 2010). Geographic relief maps were used to help identify regions of occurrence and potential barriers to

species limits, such as mountain ranges.

Depository abbreviations are as follows: AMNH (American Museum of Natural History, New York, New York);

DEBU (School of Environmental Sciences, University of Guelph, Guelph, Ontario, Canada); CNCI (Canadian

National Collection, Ottawa, Ontario, Canada), FMNH (Field Museum of Natural History, Chicago, Illinois); INBC

(Instituto Nacional de Biodiversidad, Santo Domingo de Heredia, Costa Rica); MHNM (Museum National

d’Histoire Naturelle, Paris, France); MIZA (Museo del Instituto de Zoología Agrícola Francisco Fernández Yépez;

Universidad Central de Venezuela, Maracay, Venezuela); MUSM (Museo de Historia Natural, Universidad

Nacional Mayor de San Marcos, Lima, Peru); MZSP (Museu de Zoologia, Universidade de São Paulo, São Paulo,

São Paulo, Brazil); NHMW (Vienna Museum of Natural History, Vienna, Austria), QCAZ (Departamento de

Biología, Pontífica Universidad Católica del Ecuador, Quito, Ecuador); ROME (Royal Ontario Museum, Toronto,

Ontario), UASC (Museo de Historia Natural Noel Kempff Mercado, Santa Cruz de la Sierra, Bolivia); UNAM

(Universidad Nacional Autónoma de México, Mexico City, Mexico); USNM (United States National Museum of

Natural History, Smithsonian Institution, Washington, D.C., U.S.A.); UVGC (Colleción de Artrópodos, Universidad

de Valle de Guatemala, Guatemala City, Guatemala). Deposition of type material was determined by the source of

the material and/or repatriation agreements with the country of origin. Material is deposited in DEBU unless

otherwise noted.

2.3 Compound Microscopy Photography and Illustration

A Canon PowerShot S5IS with an ocular mount paired with a Leitz Laborlux 11 compound microscope

was used to capture images of male and female genitalia. Series of images were combined using Zerene Stacker

version 1.04 (Zerene Systems LLC, Richland, WA, U.S.A.) with the DMax algorithm and manually edited.

Additional editing with Adobe Photoshop CS5 (Adobe, San Jose, California, U.S.A.) was done to generate

standardized plates. A standard complement of genitalic images is given for all species, except in cases where

structures were broken or otherwise unavailable. For males the following standardized photos were provided: a

ventral view of the terminalia distal to sternite 4; a close up of sternite 5 (usually including the anterior portion of

synsternite 6+7); posterior and lateral views of the cercus, surstylus and epandrium; a close up of either the surstylus

or postgonite (if not visible in the other images); and dorsal, dorsolateral and lateral views of the internal genitalia to

- 7 -

show the various sclerites and membranes. Photographs of females included a dorsal, lateral and ventral view of the

terminalia and a composite image of the spermatheca. In a few cases, the photographs were accompanied by

previously drawn illustrations to provide an atlas of the various structures. Descriptions refer to structures in the

standard orientation shown in the figures.

2.4 Morphology

External morphological terminology follows Cumming and Wood (2010), and internal morphological terminology

follows Smith and Marshall (2004), with the following modifications. Seta(e) and setula(e) are the large and small

socketed macrotrichia, respectively. The M1 and CuA1 stubveins refer to the portion of each vein that extends

beyond cell dm-cu. M1 is considered traceable to the wing margin when the melanistic distal remnants of M1

(referred to as “pseudoveins” by some authors) continue to the wing margin (best observed with pale background).

The spermathecal stem is used to describe the individual duct of each of the paired spermatheca. Figures 2.1–2.2

illustrate the head and thoracic setae and setulae. Figure 2.3 illustrates the mid tibial chaetotaxy. Figures 2.4–2.5

illustrate the wings of various species groups in the Archiceroptera genus group; Figure 2.6-2.7 illustrates the male

terminalia. Figure 2.8 illustrates the female terminalia.

Measurements and ratios

The measurements and ratios are based on a minimum of 10 specimens (if available), including a variety of

collections and localities. Body length should be treated as an approximation as different preservation and drying

methods can alter the length of membranous tissue between sclerotized plates. The following measurements and

ratios are used.

Body Length: distance from the front of the head (excluding antennae) to the tip of the abdomen.

Eye height: the largest vertical distance from the bottom of the compound eye, as observed in lateral view.

Genal height: distance from the most ventral portion of the compound eye to the margin of the gena (usually the

narrowest vertical distance), as observed in lateral view.

Costal sectors 2 and 3: sectors of the costal vein between radial vein apices.

CHAPTER 3 – RELATIONSHIPS OF THE ARCHICEROPTERA GENUS COMPLEX

The epandrial process group (EPG), the group of genera including the Archiceroptera genus complex, is

currently diagnosed by the finger-like process extending medially from the right anteroventral angle of the

epandrium along the posterior margin of sternite 8 (Marshall and Cui 2005, Smith and Marshall 2004). This process

is otherwise unknown in the Limosininae and this unique structure is considered a synapomorphy for the EPG.

Although this process is usually finger like, Yau and Marshall (2017) found that the epandrial process was variable

within the genus Bromeloecia; in some species it forms a bridge from the right to the left side of the epandrium

while in other species it is almost completely absent. The structural variability of the epandrial process within

Bromeloecia, a genus strongly supported by independent characters, suggests that it may be subject to rapid change.

We treat it here as uniquely derived in the EPG group as this structure is known only from New World taxa and is

correlated with both mid tibial chaetotaxy and wing venation development.

Molecular and morphological character sets were examined to provide the first phylogeny of the

EPG. A preliminary molecular analysis of the Sphaeroceridae using five prime region of cytochrome c oxidase I

(COI 5P) was done to examine the support for a monophyletic EPG and what, if any, relationships there were with

other limosinine genera. A narrower analysis of COI 5P for species within the EPG was done to examine the

relationships within the group. Finally, a morphological analysis of the EPG was done to establish the relationships

between the described genera and unplaced species groups. The entire EPG was considered as the relationships

between the groups within the Archiceroptera genus complex with the rest of the EPG was unclear.

3.1 Materials and Methods

3.1.1 Molecular Analysis

Available sequences from all genera of the Limosininae were gathered from BOLD systems

(http://www.boldsystems.org), including public data. Exemplar specimens for each group within the Archiceroptera

genus complex were submitted, if adequate material was available, to the Biodiversity Institute of Ontario for

extraction, amplification and sequencing. Recently collected material from within the past 10 years was

preferentially used, but generally the material available was of limited value for sequencing because it was taken in

pan traps, and often deteriorated in pan trap fluid prior to storage in alcohol. Sampling methods that collected

- 17 -

specimens directly into alcohol (e.g., Malaise traps) generally yield better material for sequencing but relatively few

specimens in the EPG are taken by these methods. Additional identified sequence data was obtained through

examination and the identification of digital images of sequenced but unidentified Limosininae. A dataset DOI of

the sequences used in these analyses has been requested and will be provided if future publication of this work; a

BOLD dataset of all the sequences is available online at www.boldsystems.org as dataset DH-SPHSMP.

Sequence data was imported from BOLD into Mesquite (Maddison and Maddison 2017) and aligned by

hand. In total, 300 sequences, including representatives from the Archiborborinae, Copromyzinae, Sphaerocerinae,

Homalomitrinae and Limosininae were included in the broader analysis. In the narrower EPG, a total of 133

sequences were included, including all described genera except Aptilotella, which did not have sequence data

available. Sequences less than 600bp were not included to maximize comparable base pair data, with the exception

of four Archiceroptera genus group sequences in the EPG analysis. The sequences were exported into PhyML 3.0

(Guindon et al. 2010) for maximum likelihood analysis (GTR+G+I substitution model and SPR tree improvement;

node support used aBayes fast likelihood-based support).

3.1.2 Morphological Analysis

A character matrix (Table 1) of 42 characters was generated for EPG genera using Mesquite (version 3.10;

Maddison and Maddison 2011), and exported for analysis in TNT (Goloboff et al. 2008). A Traditional Search with

10 random seeds and 5000 replications using the tree bisection reconnection (TBR) swapping algorithm was used

for the analysis. Bootstrap and Jackknife values were calculated with 100 replications and reported for values larger

than 50. Trees were optimized in WINCLADA (Nixon 2002).

There is no established outgroup to the EPG. Papp (1977) considered Archiceroptera as part of the

Ceroptera genus group (sensu Papp 2008). Archiceroptera females do not have the telescopic terminalia, nor does

either sex have reduced abdominal sclerotization, or the enlarged puvilli and claws used by Papp (1977) to define

the group. The remaining characters Papp (1977) used are either ground plan for the Limosininae (3 spermathecae),

derived but widely occurring in the Limosininae (e.g., cup absent, tibial spur), or are unclear in his diagnosis (leg

chaetotaxy). In the absence of any putative synapomorphies between Archiceroptera and Ceroptera + Ceroptella,

we do not consider Ceroptera or Ceroptella as closely related to the EPG. Trachyopella was also suggested as a

possible sister group to Bromeloecia or Rudolfina before the EPG group was recognized (Marshall 1983b, Roháček

http://www.boldsystems.org/

http://www.boldsystems.org/index.php/Public_SearchTerms?query=DS-SPHSMP

- 18 -

and Marshall 1986) and is now considered a sister group to Thoracochaeta (Marshall and Roháček 2000). In the

absence of an established outgroup, New World limosinine genera were compared with a generalized EPG ancestor

and two possible outgroups, Thoracochaeta and Archicollinella. Archicollinella shares with a generalized EPG

ancestor in having three strong anterodorsal setae (one basal, one at the midlength and one apically) and a strong

posterodorsal seta on the mid tibia, the male mid tibia has an apical setal comb, and the male cercus is basally free

from the epandrium. The setal orientation found in Archicollinella and the EPG is not commonly found in other

New World Limosininae (many genera have lost the anterodorsal seta near the midlength). Thoracochaeta shares

with the hypothetical ancestor a weakly bilobed surstylus and a distally broadened distiphallus; the mid tibial

chaetotaxy of Thoracochaeta is consistent with the EPG but it is much more variable compared with Archicollinella.

Both Thoracochaeta and Archicollinella also have a row of inclinate orbital setulae, which occurs in several but not

all EPG (apparently reduced or secondarily lost in these groups).

List of characters used in the morphological analysis of the EPG

The following 42 morphological characters are organized by body region and sex. Character states were polarized

using Thoracochaeta and Archicollinella as outgroups. Multistate characters that had clear linear transformation

3.2 RESULTS

3.2.1 Specimen Sequencing

Of the 48 specimens submitted for sequencing, only 20 (41.7%) returned sequences, and only 12 (25%)

were greater than 500 base pairs. Specimens less than 5 years old returned proportionally more sequences, but no

substantial differences were noticed with the age of specimens for sequences of greater than 500 base pairs.

Collection method appeared to have an impact on the sequence success and quality, with Malaise traps providing the

largest bp/sequence, and pan traps having the lowest bp/sequence. The difference in the quality and number of

returned sequences between the collection methods is likely a result of the medium that the flies were collected into.

Most Malaise traps samples were collected directly into alcohol, while most pan trap samples were collected using

soapy water and later transferred to alcohol.

3.2.2 Maximum-likelihood Analyses

Figures 3.1–3.2 and 3.3 show the maximum likelihood trees for the broad (sphaerocerid) and narrow (EPG)

analysis, respectively. In the broad analysis, there was poor resolution of the subfamilies. In the broad analysis, the

EPG, the Archiceroptera genus complex and most limosinine genera were not recovered as monophyletic suggesting

a limitation for the use of COI in Sphaeroceridae higher phylogeny. A subsequent analysis that excluded the third

codons provided a similar tree. As such, no insight into a possible sister group for the EPG was available. Within the

narrower analysis, Pterogramma sequences provided the most well-sampled taxon.

Within the Archiceroptera genus complex, Archiceroptera ternum-group and the A. brevivilla-group were

recovered together with strong support in both analyses. Rudolfina was not recovered as monophyletic in either

analysis; R. rozkosnyi and R. digitata were recovered together, while R. exuberata was consistently recovered with

[ternum-group + brevivilla-group] in the broad analysis and with the Extension group in the narrower (EPG)

analysis. The remaining groups were recovered with both EPG and other limosinine genera in the broader analyses.

The prominens group was recovered as sister to [Archiceroptera Extension-group + Robustagramma] +

Bromeloecia in the EPG (narrower) study, or Pterogramma (in part) in the broader analysis. The enigmata and

sororcula groups were largely recovered with the prominens group in the narrower (EPG) analysis.

3.2.3 Morphological Analysis

A Traditional Search (TNT) with 5000 replications and 10 random seeds using TBR found 11 trees (length

87; Ci = 50 Ri = 66) out of 5,553,331 arrangements, summarized here as a strict consensus tree and majority rules

tree (Fig. 3.4). Bootstrap and Jackknife values > 50 are given on the strict consensus tree. Characters were optimized

on one tree selected from the eleven equally parsimonious trees (Fig. 3.5). This tree was selected from the other ten

trees by excluding both outgroups (i.e. Thoracochaeta and Archicollinella) to provide a monophyletic EPG and with

the sororcula and enigmata groups as sister groups based on shared male genitalic characters.

3.3 DISCUSSION

Both molecular and morphological datasets did not recover the Archiceroptera genus complex as a

monophyletic group. The EPG was not recovered as monophyletic in the broader limosinine analysis but this

apparent paraphyly may have resulted from the weak phylogenetic signal within COI. Both Trunz et al. (2016) and

- 22 -

Ekrem et al. (2016) found poor phylogenetic signal within COI compared to other genes, and Trunz et al. (2016)

suggested that COI is not informative for groups that have diverged more than 4 mya. The oldest known fossil

Limosininae are from Dominican amber (see Marshall et al. 1999), dated between 13-20 mya and belong to extant

genera, so it is very possible that many limosinine genera or generic groups will not be recovered as monophyletic

using COI data. The use of COI for understanding species relationships within a single genus will be examined

further with Archiceroptera (Chapter 6). The relatively small taxon sampling size within both the broader

Limosininae and within the EPG combined with the low quality of the EPG material for molecular study may have

further limited the recovery of a monophyletic EPG and it is important that future studies try to include taxa that are

not represented in the current dataset. However, Rokas and Carroll (2005) suggest that an increase in the number of

genes is more helpful in resolving phylogenies than the addition of further taxa and future studies will need to obtain

suitably preserved material to test this within the Limosininae.

Within the Archiceroptera genus group, Archiceroptera mahukani group and Rudolfina were recovered in

the morphological analysis (along with the molecular analysis) as distinct genera that were more closely related to

other EPG genera than they were to each other. The modified spinose female cercus that originally confused the two

genera is a convergence that likely reflects a common ovipositing behaviour in the females. The recovery of

Archiceroptera mahukani group + [ternum-group + brevivilla-group] was consistent in both analyses, but in the

molecular data it was somewhat confounded by the recovery of R. exuberata and Pterogramma sequences between

Archiceroptera mahukani group and [ternum-group + brevivilla-group]. Rudolfina exuberata is considered to be a

derived species within Rudolfina with strong morphological support for its treatment there (see Chapter 5). The

recovery of these two taxa within Archiceroptera mahukani group + ternum-group + brevivilla-group may be due to

long branch attraction. The treatment of the ternum-group and brevivilla-group together was supported by both

molecular and morphological analyses, although the molecular analysis recovered the brevivilla-group as a subgroup

within the ternum-group. The posterolateral fusion of female tergite 7 to tergite 8 and the presence of dorsal basal

seta on the mid tibia are considered here as synapomorphies for Archiceroptera + ternum-group + brevivilla-group.

The Extension group is treated here as a basal lineage of Archiceroptera, supported by four female abdominal

characters: the teardrop-shaped female cercus, the apically flattened seta on the cercus, the medially

weakened/divided epiproct, and the medial division of sternite 8. This is also consistent with the EPG analysis, with

the Extension group recovered as sister to Archiceroptera mahukani group. (excluding the R. exuberata and

- 23 -

Pterogramma sequences discussed previously). Although there are morphological differences that can separate the

Extension group from the rest of Archiceroptera, they are considered here as either plesiomorphic characters for the

clade or as synapomorphic characters for the Extension species group.

The three remaining species groups are here treated as two clades that warrant treatment as genera. The

prominens group was previously treated as part of Rudolfina, and includes only two species. This group was

recovered as a sister group to either Robustagramma or Archiceroptera in the 11 morphological trees. Both

molecular analyses recovered it outside and distant to Robustagramma, Archiceroptera and Rudolfina, which

suggests that it is not a derived clade within any of those genera. We treat it here as a separate genus (see chapter 4).

The sororcula and enigmata groups were retained as sister groups in the morphological analysis, and are unique

from other members of the Archiceroptera genus complex as the male mid femur has lost the ventrobasal setal

cluster and the female terminalia are telescopic, unlike all EPG genera except Bitheca. In the EPG molecular

analysis, these two groups were recovered together with the prominens group. The EPG major diversity is

centered in the Neotropics although several clades appear to have dispersed into the Nearctic (and one into the

Palaearctic). Archiceroptera (including the ternum-group and brevivilla-group) and the prominens group appear to

be the only EPG genera that have remained largely Neotropical (two Archiceroptera species ranges extend into

several highland sites in Mexico), while Rudolfina is the only EPG genus that is largely Nearctic. There is relatively

little geographic overlap of Rudolfina and Archiceroptera, with the exception of the widespread R. exuberata. Both

Archiceroptera, to the north, and. Rudolfina, to the south, have distributions that are apparently limited by the

Isthmus of Tehuantepec (see Barrier et al. 1998). The relatively low elevation gap that occurs in the Isthmus appears

to be a significant barrier to the primarily high elevation Rudolfina, while the mountains to the north have limited

the primarily low elevation Archiceroptera.

There are still gains to be made in further examining the relationships both within the EPG and within the

Limosininae. Future studies should look at obtaining suitable material, collected and preserved appropriately, to

expand on the molecular study to include of nuclear genes. Further resolution of the EPG phylogeny may be assisted

by inclusion of character sets not considered here, but that have been utilized in other studies. The use of wing

interference patterns (WIP) (Shevtsova et al. 2011) was shown by Yau (2017) to provide some phylogenetic signal

in Bromeloecia and could be of some value in support of relationships between genera. They are known to also

occur in Pterogramma, and Robustagramma, but no distinct patterns have been observed in Archiceroptera, the

- 24 -

prominens group, or Rudolfina. Some members of the sororcula and enigmata groups appear to have consistent WIP

patterns but the homology of this character set with the other genera is not clear.

CHAPTER 4 - PECTINOSINA, A NEW NEOTROPICAL GENUS OF LIMOSININAE

(DIPTERA: SPHAEROCERIDAE)

4.1 Abstract

Pectinosina nov. gen. is described to include P. prominens (Duda) and P. carro n. sp., two

Neotropical species with an unusual comb-like posterolateral margin of female tergite 8 and a mid

tibial chaetotaxy that separates it from related genera.

4.2 Introduction

The genus Pectinosina is described to include P. prominens (Duda), a species frequently collected

in dung and carrion traps from Central and South America, and P. carro n. sp. from South America.

These species will key out to the “Archiceroptera genus complex” in couplet 78 in Marshall and

Buck (2010). Pectinosina is defined by the pectinate female tergite 8 (Fig. 3B and C), and the mid

tibial chaetotaxy, which has 4–6 setae anterodorsally on the basal 1/3, 3–4 smaller setae

posterodorsally near the midlength and five dorsal setae on the apical 1/3 (Fig. 1C). The

relationships between Pectinosina and other related genera are discussed.


All specimens examined were dried and most were point-mounted with white glue. Abdomens of

selected specimens were removed and cleared by immersion into hot 10% potassium hydroxide for

6-10 minutes before being neutralized with 10% acetic acid for 10 minutes, rinsed in deionized

water, and then placed into glycerin for examination. Dissected genitalia were stored in glycerine in

microvials pinned below the specimen.

Label Data and Distribution Maps

Label data are presented in a standardised form. Short-forms or abbreviations used on the labels are,

where possible, given in full. Geographical coordinates are given if present on the original label.

Specimens were given unique identifiers and their collection data was captured within the BIOTA

- 32 -

database at the University of Guelph Insect Collection (Guelph, Ontario, Canada); this data will

ultimately be hosted on Canadensys but is not repeated in the text except for holotypes or as image

reference. Collection data for paratypes and other specimens examined were organized

alphabetically by country, state/province, and locality name. Species distribution maps (Fig. 4.6)

Terminology

External morphological terminology follows Cumming and Wood (2010), Marshall and Buck

(2010) and Smith and Marshall (2004) with some modifications as follows. Seta(e) and setula(e) are

the large and small socketed macrotrichia, respectively. The CuA1 stubvein refers to the portion of

CuA1 that extends beyond cell dm-cu. Internal morphological terminology follows Smith and

Marshall (2004) and Paiero and Marshall (in prep.). The spermathecal stem is used to describe the

individual ducts of each of the paired spermatheca.

- 35 -

triangular. Postgonite with apical ½ narrow. Basiphallus simple (epiphallus absent). Distiphallus:

basal sclerite present; U-shaped sclerite present; dorsal sclerite whip-like and projecting distally

beyond the tip of the acrophallus; acrophallus well-developed, with mid-lateral projections; lateral

flanking sclerite extending from base of dorsal sclerite lateroventrally at base of acrophallus;

acrophallus with distinct lateral spinose projections; distal ventral sclerite present but poorly

developed.

Female Abdomen: Terminalia short and broad, not telescoping. Tergite 8 dorsally desclerotized and

divided into 2 lateral sclerites; lateral sclerites with 3–4 teeth on posteroventral margin; ventral

surface, near anterolateral corner, with small process. Epiproct evenly sclerotized, hirsute with pair

of seta near midlength. Cercus ovoid and relatively short, not projecting posteriorly beyond the tip

of the abdomen; surface setose with 2–4 larger setae near tip. Sternite 7 with posterior margin

evenly rounded. Sternite 8 transverse, entire and poorly sclerotized with cluster of 2-3 setulae on

membrane posterior to posterolateral corners of sclerite. Hypoproct narrow, transverse, horseshoe

shaped. Spermathecae (2+1) biconcave discs with elongate sclerotized ducts.

Etymology: The genus name is derived from the Latin word for comb (pectine) and used in

combination with “-sina”, a common ending used in a number of Limosinine genera. Gender

feminine.

Biology: Most material of this group was collected in dung traps, or in pan traps associated with

dung or carrion baits. Specimens have also been collected in Malaise and flight intercept traps.

Label data for some specimens of Pectinosina prominens (Duda) indicate an association with dung

rolling scarabs (see species discussion).

Relationships: Pectinosina prominens Duda was originally treated in Acuminiseta (as a subgenus of

Leptocera; Duda 1925) but was placed in Rudolfina Roháček by Roháček et al. (2001) because it

was more similar to, and more closely related to, Rudolfina than to Acuminiseta (which does not

occur in the New World). Pectinosina prominens does not, however, fit within the genus Rudolfina

as recently redefined by Paiero & Marshall (in prep.). A morphological phylogeny of the epandrial

process group (Chapter 3), a primarily New World clade recognized by Marshall and Cui (2004) to

include Rudolfina, Robustagramma Marshall & Cui, Archiceroptera Papp, Pterogramma Spuler,

- 36 -

Aptilotella Duda and Bitheca Marshall, recovered Pectinosina with Robustagramma. However,

Pectinosina does not fit with Robustagramma as it is currently defined (Marshall and Cui 2004),

and while Robustagramma could be redefined to include Pectinosina as a basal clade, to do so

would make Robustagramma less diagnosable, and we consider the apomorphic mid tibial

chaetotaxy and female terminalia enough support to warrant its treatment as a unique genus outside

of Robustagramma.

The habitus and mid tibial chaetotaxy of Pectinosina is superficially similar to Leptocera, and the

female tergite 8 of some Leptocera species are margined posteriorly with numerous modified setae

to make it appear pectinate. Despite some general similarities between the two genera, Leptocera

does not belong within the EPG as it lacks the epandrial process. The similarity of tergite 8 between

the genera is certainly homoplastic as the combs in Pectinosina are a modification of the sclerite and

not the setae as in Leptocera. Pectinosina may also be confused with the closely related

Archiceroptera, which can be easily separated by M1 extending to the wing margin, the mid tibial

chaetotaxy and several differences in the female terminalia, including the spinose cercus.

4.4.1 Species Descriptions

Pectinosina species are externally indistinguishable and species identification requires close

examination of the male or female abdomen. The following descriptions are therefore limited to

abdominal characters.

Pectinosina prominens (Duda), n. comb

Synonyms: Rudolfina prominens (Duda, 1925); Leptocera (Acuminiseta) prominens Duda 1925

Description: Length 1.4-3.1 mm. Eye height ~2.0–2.4× genal height.

Male Abdomen (Fig. 4.4): Sternite 5 posteriorly with pair of acute teeth on each side of medial

desclerotization; posterior margin sinuate lateral to teeth; medial desclerotization “T” shaped with

transverse desclerotization 1/5th from anterior margin, and with elongate desclerotization extending

to posterior margin. Epandrium with numerous setae. Surstylus (in lateral view) hirsute with

- 37 -

anterior and posterior lobes (may appear trilobed in lateroventral view); anterior lobe boot-shaped

with square “toe” and sinuate distal edge; posterior lobe simple but pronounced, with two short

robust setae on inner surface. Cercus acute, as long as surstylus, with apex abruptly posteriorly

recurved. Distiphallus (Fig.4. 4G-I): first dorsal sclerites elongate, projecting beyond tip of

acrophallus by approximately half the length of sclerite before tip; acrophallus with rounded mid-

lateral projections.

Female Abdomen (Fig. 4.5): Tergite 7 with posterior margin usually with a small V-shaped

emargination (sometimes reduced to small concavity or absent entirely). Lateral sclerites of tergite 8

posteriorly with 3 (rarely) or 4 (usually) ventral teeth Paired spermathecae each with stems slightly

less than width of spermatheca and with sclerotized portion of common duct ~1/3 length of stems;

single spermatheca with sclerotized duct length slightly less than width of spermatheca.

Distribution: Widespread in the Neotropics.

Comments: Pectinosina prominens is the most frequently collected and widely distributed species

in the Archiceroptera genus group, with a largely Neotropical distribution across a wide range of

altitudes and latitudes. Two labels for P. prominens indicate the flies were found associated with

dung rolling scarabs in Costa Rica: Grieg found a male around a dung ball rolled by Canthon

moniliatus Bates in La Selva, and Gill found a male and female sitting on the elytra of

Sulcophanaeus velutinus (Murray) in San Vito. Other sphaerocerid genera are well known

kleptoparasites of scarab beetles (see Sivinski et al. 1999 and references therein), but the

observations of P. prominens with the scarabs may simply be of insects attracted to the same bait.

Pectinosina carro Paiero & Marshall, new species

Description: Length 1.8-2.8 mm. Eye height ~2.0-2.2× genal height.

Male Abdomen (Fig. 4.2): Sternite 5 with large discal area desclerotized; desclerotized area

approximately circular, extending posteromedially to divide posterior margin; posterior margin on

each side of break with numerous robust blunt setae. Epandrium hirsute with setae equal in length.

Surstylus bilobed; anterior lobe boot-shaped; posterior lobe simple, not as prominent as in P.

prominens, with two robust setae on inner surface. Cercus acute, as long as surstylus, with apex

abruptly posteriorly recurved. Distiphallus: first dorsal sclerites elongate, projecting beyond tip of

acrophallus by more than length of sclerite before tip; acrophallus with mid-lateral projections

spinose.

- 46 -

Female Abdomen (Fig. 4.3): Tergite 7 with posterior margin entire. Lateral sclerites of tergite 8

posteriorly with 3 ventral teeth. Paired spermathecae each with stems ~0.5× width of spermatheca

and with sclerotized portion of common duct equal in length to stems; single spermatheca with

sclerotized duct length ~2/3 width of spermatheca.

B. Gill (CNCI, DEBU, MIZA); 7 males, 3 females, same as previous except 220 m; 11 males, 5

females, same as previous except 1000m (MIZA, DEBU).

Comments: Male P. carro can readily be separated from P. prominens by the shape of sternite 5

and the surstylus, and by the relative length of the dorsal sclerite of the distiphallus. Females are

more difficult to separate. Although there are usually only three teeth on each half of tergite 8 in P.

carro females and four in P. prominens, some P. prominens also have only three teeth. Furthermore,

the available material of P. carro is from a small number of collections and may not reflect the

extent of intraspecific variation that occurs. The most consistent difference between females of these

two species seems to be the relative length of spermathecal stems: the stems in P. carro are equal in

length to the sclerotized portion of the common duct, while the stems in P. prominens are longer

than the sclerotized portion of the common duct.

Etymology: The specific epithet is the Latin for “comb”, referring to the dense cluster of setae

along the posterior margin of male sternite 5.

5.1 Abstract

The genus Rudolfina is revised and redefined with the description of the following new species: R.

bucki, R. exuberata, R. howdeni, R. megepandria, R. newtoni, R. pauca, R. pilosa, R. remiforma,

and R. tumida. Rudolfina is compared to closely related genera in the Archiceroptera genus

complex, which in turn is recognized as part of a large, mostly Neotropical clade including

Robustagramma Marshall & Cui, Pterogramma Spuler, Aptilotella Duda, Bitheca Marshall,

Bromeloecia Spuler and Archiceroptera Papp.

5.2 Introduction

The genus Rudolfina Roháček 1987 was described (as Rudolfia Roháček 1982) for a single

Palaearctic species, Limosina rozkosnyi Roháček. Three species have since been described: R.

digitata Marshall and R. cavernicola Marshall & Fitzgerald from North America (Marshall 1991,

Marshall and Fitzgerald 1997) and R. zhangi Su from China (Su et al. 2017). Marshall (1982) also

- 55 -

recognized several undescribed species of Rudolfina s. str. from Mexico, but deferred publishing

descriptions of those species until adequate material was available to properly treat the Neotropical

fauna and to determine the limits between Rudolfina and superficially similar Neotropical species in

the Archiceroptera genus complex.

We here redefine the genus Rudolfina and describe nine new species following the examination of

approximately 2,000 specimens of Rudolfina and over 6,000 specimens of other species in the

Archiceroptera genus complex.

Rudolfina is diagnosed by the following characters: mid tibia with 1 proximal anterodorsal seta, 1

medial anterodorsal seta, 1 distal anterodorsal seta and 1 distal posterodorsal seta; costa with 1 well-

developed costagial seta; male sternite 5 posteromedially emarginate with darkened lobe or process

on each side of the emargination; female tergite 8 tripartite; female epiproct medially weakened;

female cercus strap-like with strong, flattened apical seta; and female abdomen with paired bisetose

sclerites posterior to sternite 8. All Rudolfina except R. cavernicola have the female cercus partially

fused with the epiproct. Most of these diagnostic characters are also defining characters that support

the genus Rudolfina, as defined here, as a monophyletic group. The strongest synapomorphies for

the genus are characters of the female terminalia, including a stout and generally upturned strap-like

cercus with a strong flattened apical seta, an epiproct that is medially desclerotized except near the

anterior margin, a middle sclerite of tergite 8 articulating with the anterior margin of the epiproct,

and a pair of small bisetose sclerites posterior to the weakly sclerotized sternite 8. The strongly

developed costagial seta is also considered a synapomorphy, as is the male sternite 5 with its

characteristic pair of posteromedial lobes separated by a medial emargination.

Related and similar genera

All Rudolfina species will key out to “Rudolfia” in the key to Nearctic Sphaeroceridae by Marshall

and Richards (1987) but they will key out as “Archiceroptera genus complex, in part” in Marshall

- 56 -

and Buck’s (2010) key to Neotropical Sphaeroceridae. This treatment reflected uncertainty about

the limits between Rudolfina and the many undescribed Neotropical species in the Archiceroptera

genus complex. Like other members of the complex, Rudolfina species have two orbital setae,

strong interfrontal setae, the costa ending at or slightly beyond R4+5, R4+5 straight or weakly curved

to costa, and the mid tibia with an apical ventral seta. The Archiceroptera complex is part of larger

group of Limosininae (including Aptilotella Duda, Archiceroptera Papp, Bitheca Marshall,

Bromeloecia Spuler, Pterogramma Spuler, and Robustagramma Marshall & Cui) characterized by

an unusual process extending medially from the lower right margin of the epandrium. Within this

group, Rudolfina resembles Archiceroptera, due to the general appearance of the highly modified

female terminalia. Most Archiceroptera differ from Rudolfina species in having more than four

strong dorsal mid tibia setae, but some have the pattern of four dorsal mid tibial setae typical of

Rudolfina. These species, however, differ markedly from Rudolfina in characters synapomorphic for

Archiceroptera (row of inclinate orbital setulae, M1 traceable to wing margin, CuA1 either not

projecting beyond the apex of cell dm or with only short (< 1/2 dm-cu) stub vein present, male

cercus either triangular or with prominent ventral process, female tergites 7 and 8 partially fused,

female sternite 8 divided into lateral triangular sclerites, epiproct completely divided) and in the

lack of other characters synapomorphic for Rudolfina species.

Biology

Roháček (1987) recorded R. rozkosnyi from dung, mud, and decaying vegetation, but most of the

new species considered here were collected in dung traps. Larvae remain unknown.

Distribution

Rudolfina has a mostly western Nearctic montane distribution, with high endemism in the southwest

and into the mountains of Mexico (Sierra Madre del Sur, Sierra Madre Oriental, and Sierra Madre

de Chiapas). Two widely separated species occur in the Palaearctic region (R. rozkosnyi and R.

zhangi) and one species (R. exuberata) is widespread at low elevations from the southern United

- 57 -

States to South America. Other than R. exuberata, no true Rudolfina are known from south of

Guatemala. Other Neotropical species previously treated as Rudolfina are discussed below.


Most specimens were collected into fluid, stored in alcohol, and later dried and point-mounted.

Abdomens of some specimens were removed and cleared in hot 10% potassium hydroxide for 6–10

minutes before being neutralized with 10% acetic acid for 10 minutes, rinsed in deionized water,

and then placed into glycerin for examination. Dissected genitalia were stored in glycerin-filled

microvials, and pinned below the specimen.

Species descriptions. All label data were presented in a consistent manner, not verbatim from the

labels; in a few cases, obvious spelling errors were corrected. Short-forms or abbreviations used on

specimen labels are normally interpreted and given in full. Geographical coordinates are given only

if present on the original label. All specimens were given unique identifiers and their collection data

were captured within the University of Guelph Insect Collection database; these are not repeated in

the text except for holotypes or for imaged specimens. The specimen data will ultimately be hosted

on Canadensys. Collection data for paratypes and other specimens examined were organized

alphabetically by country, state/province, and locality name. Distribution maps are given for all

New World species (Fig. 5.22) and were generated using SimpleMappr (Shorthouse 2010).

Terminology. The terminology for external morphology largely follows Cumming and Wood (2010)

with a few modifications given below; terminology for male and female genitalia follows Smith and

Marshall (2004) with modifications from Cumming and Wood (2010). Figures 1–4 illustrate head

chaetotaxy, wing venation, male and female genitalia. Seta(e) and setula(e) are large and small

(respectively) socketed macrotrichia. The CuA1 and M1 stub veins are the short portions of these

veins that project distally beyond cell dm. The subanal plate is the portion of the epandrium below

the anal opening. Female tergite 8 is tripartite, with the medial part free, and posteriorly articulating

- 58 -

with the epiproct; in some species, this medial part is poorly sclerotized (e.g., R. pauca). The female

abdomen has a pair of small bisetose sclerites posterior to sternite 8. These bisetose sclerites are

homologous with the posterior portion of sternite 8 in related taxa (e.g., Pterogramma and

Robustagramma; see Smith & Marshall (2004) and Marshall & Cui (2006)) and reflect a general

desclerotization of sternite 8, leaving a distinct transverse anterior portion and the paired posterior

sclerites. Body length was measured from the anterior portion of the frons to the tip of the abdomen.

Illustrations and photography. Microphotographs of male and female genitalia were obtained using

a Canon PowerShot S5IS mounted on a Leitz Laborlux 11 compound microscope. Series of images

were aligned and combined using Zerene Stacker version 1.04 (Zerene Systems LLC, Richland,

WA, U.S.A.) with the DMax algorithm. Additional editing with Adobe Photoshop CS5 (Adobe, San

Jose, California, U.S.A.) was done to enhance clarity and visibility of the genitalic characters.

Photographic plates were supplemented with drawings previously prepared for an earlier

manuscript. All plates list the unique specimen identifier for the specimen(s) photographed.

5.4 Analysis

A character matrix (Table 1) was generated using Mesquite (version 3.10; Maddison and Maddison

2011), and exported for analysis in TNT (Goloboff et al. 2008) using Traditional Search, with 10

random seeds and 5000 replications with the tree bisection re-connection (TBR) swapping

algorithm. Trees were optimized in WINCLADA (Nixon 2002).

The following 36 morphological characters used in the phylogenetic analysis are organized by body

region and sex. Character states were polarized using the hypothetical groundplan of the

Archiceroptera genus-complex as an outgroup. The three multistate characters (1, 4 and 9) were

treated as ordered. Rudolfina zhangi is only recently described and no material was available for

study. This species therefore was excluded from the phylogenetic analysis although the description

suggests that it is closely related to R. rozkosnyi, the only other Palaearctic species in the genus.

Table 1 gives the character states for each species.

5.5 Results of Phylogenetic analysis

Six most parsimonious trees were generated, summarized here as a strict consensus tree (Fig. 5.4)

and a majority rules consensus tree (Fig. 5.6). Characters were optimized on one of the equal length

trees (Fig. 5.7).

The strict consensus tree supports Rudolfina cavernicola as the sister taxon to the

remaining species, which form a monophyletic group characterized by the fusion of the female

cercus with the posterolateral corner of the epiproct, and by other characters of the male cercus and

surstylus. This tree suggests a New World origin for Rudolfina. No specimens of the Chinese

species R. zhangi were available for examination, so it was not included in the phylogenetic

- 62 -

analysis. Based on the described characters of the male genitalia (sternite 5, surstylus, cercus) it is

probably the sister species to R. rozkosnyi. The Palaearctic clade (R. zhangi + R. rozkosnyi) is

probably the sister group to the rest of Rudolfina except R. cavernicola.

All species other than R. cavernicola appear to form a clade characterized by the elongated

medial part of tergite 8, and within that clade R. rozkosnyi, R. digitata and R. tumida appear to be

basal lineages predating the origin of a clade comprising the Mexican-Guatemalan species. This

largely Mexican clade can be recognized by the loss of the laminate anterior lobe of the male cercus

and the absence of dorsal swellings on the dorsal sclerite of the distiphallus. In the strict consensus

tree this clade is largely unresolved, with only the R. exuberata group standing out as strongly

supported. The R. exuberata group (including R. exuberata, R. remiforma, and R. pauca) is

characterized by the small elongate male cercus, tulip-shaped epiproct, and a reduction of the female

cercus. Rudolfina remiforma and R. pauca are known from only a few localities at higher altitudes,

as is typical of the genus, but the widespread R. exuberata occurs at much lower altitudes than its

more localized congeners.

Molecular data:

Five Rudolfina species were sequenced for COI ("barcoded") at the Biodiversity Institute of Ontario

(University of Guelph, Guelph, Ontario) but only the North American R. digitata and the European

R. rozkosnyi yielded high quality (> 600bp) sequences. Unsurprisingly, these similar species came

out next to one another in a Maximum Likelihood Tree for the broader "epandrial process" group

(Chapter 3), and they were clustered with four Bitheca specimens. The miscellaneous

Sphaeroceridae on the Barcode of Life Database (http://www.boldsystems.org) with both high

quality sequences and associated specimen images were examined for additional Rudolfina material;

as a result, one specimen of R. exuberata was identified and included in the analysis. In the

Maximum Likelihood Tree, Rudolfina exuberata was recovered with members of the “Extension”

species group, a currently unplaced species group in the Archiceroptera genus complex. Although

this preliminary molecular analysis suggests that R. exuberata is closer to other members of the

- 63 -

Archiceroptera genus complex than to other Rudolfina, morphological synapomorphies strongly

support our treatment of this abundant species as deeply embedded in Rudolfina.

Female: Unknown

Type Material: Holotype (male, debu01086238, FMNH) and 1 paratype (male): MEXICO:

Oaxaca: Jct. Mex. 175-Yuvila Rd., 4.1 mi. W, 9300 ft, oak-fir-pine forest, 8–19 Aug 1973, A.

Newton..

Etymology: The specific name is a patronym for Dr. Matthias Buck, a friend and previous worker

on Sphaeroceridae.

Rudolfina cavernicola Marshall & Fitzgerald 1997

Distribution: Nearctic: USA (AZ, CO); Mexico (MEX, newly recorded here).

Description: See Marshall and Fitzgerald 1997.

Material Examined: The original type series from Kremmer’s Cave was re-examined along with

the following material: MEXICO: San Luis Potosi: 1 male, Cueva de Cinquenta y Ocho, 5 km S

San Francisco, 40 km E San Luis Potosi, Municipio de Zaraqoza, 3000 m, 18 May 1972, Elliott,

Ralph & Lynn.

- 71 -

Comments: This species is newly recorded from Mexico. The illustration of this species that

accompanied the original description (Marshall and Fitzgerald 1997, Fig. 1) includes what appears

to be a large seta coming off the anterior base of the surstylus; this is an unsocketed laminate lobe.

Rudolfina digitata Marshall 1991

Description: See Marshall (1991).

Comments: Rudolfina digitata, the second species to be described in this monobasic originally

Palaearctic genus, is widely distributed in western North America and also occurs in a few eastern

North American sites, including Mount Washington, New Hampshire. Mt. Washington is known to

have other species with disjunct western Cordilleran and eastern Appalachian distributions [e.g.,

- 72 -

Oeneis meillsa (Fabricius) (Lepidoptera: Nymphalidae)], and the apparently disjunct population of

R. digitata on Mt. Washington suggests it may have once had a more extensive range. The other

New Hampshire locality is also one of two known localities for the rare monotypic sphaerocerid

genus Volumosina Roháček and Marshall (Roháček and Marshall 2017), otherwise known from one

old growth forest in Ontario.

Rudolfina exuberata Paiero & Marshall n. sp.

Description: Length 1.5–2.0 mm. Eye height 2.0× genal height. Head with 4 interfrontal setae and

row of 5–6 small setulae on inner margin of orbital plate. Gena with 1 strong setae and 5–7 smaller

setulae. Acrostichal setulae in 6–8 rows. Costagial seta extending to humeral break. Second costal

sector 0.3–0.4× third costal sector. Length of M1 between crossveins dm-cu and r-m 1.2× dm-cu;

CuA1 stub vein ~3.0× M1 stub vein. Male mid femur with single ventrobasal seta. Male mid tibia

with ventral comb reduced to 1 enlarged preapical seta and 1 smaller seta near midlength. Female

mid tibia with midventral seta.

Male abdomen (Fig. 5.9): Sternite 5 with deep irregular posteromedial emargination flanked by

blunt lobe on each side; emargination extending anteriorly 1/3 length of sternite. Transverse part of

sternite 6 straight. Surstylus (in lateral view) bilobed; anterior lobe rounded and bare; posterior lobe

rounded but apically flattened and with 5–10 setae. Cercus projecting posteriorly, with apical seta.

Postgonite simple, slightly sinuate, with small robust seta apically and 1–2 setulae along length.

Distiphallus (Fig. 5.9F–H): Dorsal sclerites without distinct swellings.

Female Abdomen (Fig. 5.10): Tergite 7 with posterior margin entire. Tergite 8 with middle part

elongate, narrower anteriorly, posteriorly closely approximated with epiproct. Epiproct tulip-shaped,

heavily sclerotized; longitudinally lightly sclerotized on apical half. Cercus flattened, with distal

apical seta flattened. Sternite 7 wider than sternite 6; posterior margin with broad shallow

emargination. Spermatheca bilobed, constricted near midlength; distal portion cup-shaped, basal

portion ovoid and narrowed before duct junction; spermatheca stem as long as spermathecal width.

Comments: Rudolfina exuberata, the only Rudolfina that regularly occurs at low elevations, is

widespread throughout South and Central America as well as the southern United States.

Etymology: The specific name, which has been a manuscript name since 1982, is from the Latin for

"abundant”. Of the 1933 specimens examined for this study, 1649 were R. exuberata.

Comments: The male sternite 5, epandrium, surstylus and cercus are unique within Rudolfina.

Etymology: This species name, which has been a manuscript name since 1982, is a patronym for

Dr. Henry Howden. Henry was a great entomologist and friend who advised SAM during his M.Sc.

at Carleton University; we regret that he did not live to see this beautiful species published.

Type Material: Holotype (male, debu01086084, FMNH) and 2 paratypes (1 male, 1 female):

MEXICO: Jalisco: Atenquique, 18 mi. W, 9300 ft, fir forest, dung, A. Newton. Additional

paratypes: MEXICO: Oaxaca: 1 females, Yuvila Rd., 9400 ft, mesic oak, carrion, 9–19 Aug

1973, A. Newton (FMNH).

Etymology: The specific name, which has been a manuscript name since 1982, refers to the

unusually large epandrium.

SE, 7100ft., sage–grass, riparian, carrion, 30 Jul–11 Aug 1979, S. & J. Peck.

Comments: Male R. tumida are highly distinctive for the uniquely swollen epandrium and large

surstylus.

Etymology: The species epithet is the Latin for “swollen”, referring to the enlarged epandrium.

5.9 Described species in other genera previously treated as Rudolfina

Trachyopella opuntiae (Richards 1967)

Comments: Richards (1967) originally described this species as a Trachyopella (then a subgenus of

Leptocera), a placement that was followed by Roháček and Marshall (1986) in their review of

Holarctic Trachyopella. Pitkin (1989) transferred opuntiae to Rudolfina, in view of its modified

female cerci. Examination of type specimens, including male and female terminalia, supports the

treatment of this species as a Trachyopella.

Leptocera (Acuminiseta) prominens Duda 1925

Comments: Leptocera (Acuminiseta) prominens was provisionally treated as Rudolfina by Roháček

et al. (2001), who noted that Acuminiseta does not occur in the New World. This species does not fit

into Rudolfina as defined here, but belongs elsewhere in the Archiceroptera complex and will be

treated in a later paper (Chapter 4).

5.10 Discussion

With the exception of the widespread lowland species R. exuberata, Rudolfina is a

Holarctic, and largely Nearctic genus with highest diversity in the highlands of Mexico. The few

records from mountains in Guatemala are from an area recognized as a transitional zone between

Nearctic and Neotropical regions. This is consistent with patterns observed in some bats (Ortega and

Arita 1998), copepods (Aglaodiaptomus and Skistodiaptomus; see Suarez-Morales et al. 2005), and

passalids (Gutierrez-Velazquez et al. 2013). There are no records of Rudolfina species (other than R.

exuberata) from lowland Guatemala, southern Guatemala or any other Neotropical locality. We

have studied tens of thousands of specimens collected from throughout Costa Rica over the past

thirty years without finding any specimens other than R. exuberata that fit Rudolfina as currently

defined; this reinforces our conclusion that the distribution of Rudolfina is effectively bounded

southward by the limits of the Nearctic region. The origins of Rudolfina are likely to be in western

North America, where R. cavernicola, the basal most species, occurs, with the Nearctic and

Palaearctic faunas diverging relatively early in Rudolfina’s evolutionary history.

The number of new species in the University of Guelph insect collection and the apparent

novelty of the limited material from other collections, suggest that many further new species await

discovery. Southern Mexico is especially poorly represented in the current material. We have only a

single specimen (R. cavernicola) from the Sierra Madre Occidental range, and we have seen no

Rudolfina from the Sierra Madre Oriental. Further collecting efforts in Mexico would greatly

improve our understanding of Rudolfina.

Acknowledgements:

This work was made possible largely through the generosity of Dr. Alfred Newton

(FMNH) who kindly allowed Marshall to take the Sphaeroceridae from his Mexican beetle trap

residues during the 1980s. Of the 284 non-R. exuberata Rudolfina specimens studied for this

revision, 219 were from these residues. Despite ongoing efforts to obtain further material from

- 92 -

throughout the range of Rudolfina and related genera, the material collected by Dr. Newton during

the early 1970s remains by far the most important collection of Mexican Rudolfina.

Supplemental drawings used to support the photographs were prepared by the second

author, and by illustrator Rebecca Langstaff, for an unpublished manuscript.

Funding for this study was provided by NSERC Discovery grants to SAM, and NSERC

postgraduate scholarships to SMP.

CHAPTER 6 – A REVISION OF ARCHICEROPTERA PAPP 1977

6.1 Abstract

The genus Archiceroptera Papp (Diptera: Sphaeroceridae: Limosininae), an almost entirely

Neotropical genus ranging from southwestern USA to Argentina, is revised to include 29 species,

including the following 27 new species: A. adamas, A. addenda, A. barberi, A. basilia, A. bilobata,

A. bisetosus, A. braziliensis, A. brevivilla, A. browni, A. caliga, A. calligraphia, A. cobolorum, A.

crenulata, A. curvivilla, A. dolabra, A. llama, A. maniba, A. masoni, A. megacercus, A. megavilla,

A. mexicorona, A. mitarakai, A. paracercus, A. pussula, A. ternum, A. triclavus, and A. unicinata. A

species phylogeny based on morphological characters is provided and all species are keyed.

6.2 Introduction

The genus Archiceroptera Papp 1977 was originally described to include two South

American species: A. mahukani Papp and A. venezolana (Richards). Based on a study of over 3600

specimens, we here redefine Archiceroptera to include 29 species, 27 of which are newly described.

Archiceroptera belongs to a group of genera characterized by the presence of an epandrial process

that extends from the right side along the posterior margin of sternite 8 towards the hypandrium

(Marshall and Cui 2005). The strongest synapomorphies for Archiceroptera within this clade are:

vein M1 reaching the wing margin as a tracable fold, section of M1 between r-m and dm-cu > 3.0×

length of dm-cu, and female cercus elongate with a strong apical seta. The female sternite 8 is

medially divided (except in the putatively plesiomorphic A. addenda species group) into a pair of

elongate glabrous lateral sclerites. Within Archiceroptera, four species groups are here recognized

(Archiceroptera mahukani group, the A. addenda group, the A. ternum group and the A. brevivilla

subgroup).

- 120 -

6.2.1 Biology

Most Archiceroptera species occur at low elevations (< 500m) but collections range from

0–2000m. Most of the specimens used in this revision were collected using dung and carrion traps.

Larval habitats remain unknown.

6.2.2 Related genera

Archiceroptera, along with Rudolfina and several unplaced species groups, were originally treated

in the Archiceroptera genus complex (Sphaeroceridae: Limosininae) sensu Marshall and Buck

(2010), and these clades all belong to a larger clade including Aptilotella Duda, Bitheca Marshall,

Bromeloecia Spuler, Pterogramma Spuler, and Robustagramma Marshall & Cui (Marshall and Cui

2005). This larger clade is loosely referred to as the epandrial process group (EPG) because it is

characterized by the presence of a finger-like process extending from the lower right corner of the

epandrium along the posterior margin of sternite 8. A morphological phylogeny of the EPG

(Chapter 3) found the Archiceroptera genus complex was rendered paraphyletic by other genera.

In Marshall and Buck's (2010) key to the Neotropical genera of Sphaeroceridae,

Archiceroptera will key out to the Archiceroptera Papp genus complex and run to couplets 32

(Archiceroptera mahukani group), 72 (A. brevivilla group), 76 or 78 (A. ternum and A. addenda

groups). Archiceroptera can be separated from other members of the Archiceroptera genus complex

by the characters given in the diagnosis.


All specimens examined were dried and point-mounted. Abdomens of some specimens were

removed and cleared by immersion into hot 10% potassium hydroxide for 6-10 minutes before

being neutralized with 10% acetic acid for 10 minutes, rinsed in deionized water, and then placed

into glycerin for examination. Dissected genitalia were stored in glycerine in microvials pinned

below the specimen.

Species Descriptions.

All label data are presented in a consistent manner, not verbatim from the labels; in a few cases,

obvious spelling errors were corrected. Short-forms or abbreviations used on the labels are, where

possible, given in full. Geographical coordinates are given only if present on the original label.

Specimens were given unique identifiers and their collection data was captured within the BIOTA

database (BIOTA 3.0, Colwell 2012); this data will ultimately be hosted on Canadensys

(www.canadensys.net) but is not repeated in the text except for holotypes or as image reference.

Collection data for paratypes and other specimens examined were organized alphabetically by

country, state/province, and locality name. Species distribution maps (Figs. 6.62–6.64) were

generated using SimpleMappr (Shorthouse 2010).

Terminology

Terminology for external morphology follows Cumming and Wood (2010) with some modification.

Mid tibial dorsal chaetotaxy follows Buck and Marshall (2009). Male and female genitalia follow

Smith and Marshall (2004), with modifications from Cumming and Wood (2010), as labelled in

Figs. 6.5–6.7. The CuA1 and M1 stub veins are short portions of these veins that project distally

beyond cell dm. The subanal plate refers to the fusion of the epandrium below the anal opening.

Female tergite 8 is treated here as tripartite, with the medial part articulating posteriorly with the

epiproct (this medial sclerite is present but poorly developed in the A. addenda species group). The

female sternite 8 is entire (plesiomorphic species) or medially desclerotized with two lateral

triangular sclerites; a transverse posterior sclerite is also present in the A. addenda and A. mahukani

species groups. Body length was measured from the anterior portion of the frons to the tip of the

abdomen.

6.4 Archiceroptera Papp 1977

Type species: Archiceroptera mahukani Papp 1977

6.4.1 Diagnosis

Archiceroptera is diagnosed by the following characters: interfrontal setae in 3–6 pairs, two or more

inclinate orbital setulae in a single row; R4+5 straight or weakly curved just before meeting costa; M1

- 123 -

traceable to wing margin; male cercus free and articulating, either triangular or with distinct distal

medial process; female cercus glabrous and widened basally (usually appearing droplet-shaped)

with a strong flattened apical seta; and female sternite 8 reduced to a pair of lateral triangular

sclerites (except in the A. addenda species group). The mid tibia in all Archiceroptera (as with most

genera in the epandrial process group) has three strong anterodorsal setae (one near basal ¼, one

near mid length and one near distal ¼) and one distal posterodorsal seta, although many species

have additional seta both anterodorsally and posterodorsally; ventrally all species have a distinct

row of robust dark setae apically and most males have a long midventral seta. The modified female

cercus and sternite 8 are considered defining characters.

6.5 Phylogeny

6.5.1 Morphological

A character matrix (Table 1) of 58 morphological characters organized by body region and sex was

generated using Mesquite (version 3.10; Maddison and Maddison 2011), and exported for analysis

in TNT (Goloboff et al. 2008) using traditional Search, with 10 random seeds and 5000 replications

using the tree bisection reconnection (TBR) swapping algorithm.. Trees were optimized in

WINCLADA (Nixon 1999–2002). Character states were polarized using Thoracochaeta as an

6.5.3 Molecular sequences

Cytochrome c oxidase subunit I (COI) 5P sequence data for Archiceroptera was obtained through

two methods. Identified material for the four Archiceroptera species groups were submitted to the

Barcode Institute of Ontario for extraction, amplification and sequencing, where adequately

preserved material was available. As no identified material was previously available on BOLD

systems (http://www.boldsystems.org), public specimens/sequences with associated images were

examined for unidentified Archiceroptera to increase the number of sequences available for study.

The prominens group was included as the outgroup and sequences were obtained from both

submitted material and examination of unidentified public material. A total of 20 Archiceroptera

and 4 prominens group sequences were imported from BOLD into Mesquite (Maddison and

Maddison 2017) and aligned by hand. Two datasets of this sequence data were exported into

PhyML (Guidon et al. 2010) for maximum likelihood analysis; one including all codons and one

excluding the 3rd codon. The GTR+G substitution model with SPR tree improvement was used for

the all inclusive dataset, while the dataset excluding the 3rd codon used the TN93+G substitution

model and SPR tree improvement, based on the AIC estimates provided by PhyML.

consistency index = 34, retention index = 62) from 1,207,586 rearrangements, summarized here as a

strict consensus tree (Fig. 6.1) and a majority rules consensus tree (Fig. 6.2). Bootstrap and

Jackknife values > 50 are given on the strict consensus tree. Characters were optimized on one of

the 70 trees (Fig. 6.3). This tree was selected because it included the following species pairs, which

are considered here to be sister species: A. venezolana and A. browni as sister species (based on

shared reduction of the ocelli), A. megacerca and A. paracerca as sister species (based on the shared

mid tibial chaetotaxy and male surstylus characteristics), A. adamas and A. maniba as sister species

(based on shared male sternite 5 characteristics), and A. calligraphia and A. dolabra as sister species

(based on shared male sternite 5 characteristics).

The two molecular phylogenies included substantially less species and provided slightly

differing topologies from each other and from the morphological analysis. Both molecular and

morphological analyses recovered the A. addenda group + [A. mahukani group + A. ternum group],

but the topology of the larger A. ternum group varied between all datasets. The inclusive dataset

(Fig. 6.4A) and the dataset that excluded the 3rd codon (Fig. 6.4B) both recovered the A. brevivilla

subgroup as sister to the rest of the A. ternum group, but differed in the topology of the rest of the A.

ternum group. This may be a result of poor molecular representation from within the speciose A.

ternum group, and inclusion of representatives of other clades would be required in future analyses

to determine if this is a sampling artifact or if the A. brevivilla subgroup is sister to the A. ternum

group.

Based on both the morphological and molecular analyses, the following clades are

recognized: the A. addenda species group, A. mahukani species group, the A. brevivilla species

subgroup, and the A. ternum species group. The first three clades were recovered in all 78 trees,

while the A. ternum species group was recovered in 61 of the trees. Based on the tree depicted in

Figure 6.3, the A. addenda group was recovered as the basal-most clade supported by the following

- 131 -

synapomorphies: strong anterior katepisternal seta, male sternite 5 with posterior secondary sclerite,

distiphallus heavily sclerotized, and female cercus longitudinally desclerotized near the base. The

remainder of Archiceroptera forms a clade supported by the following synapomorphies: the male

cercus is ovoid with astrong ventral process, the distiphallus has a long dorsal sclerite, female tergite

7 is posterolaterally approximated or fused to the anterolateral corner of tergite 8, female tergite 8

with medial sclerite, epiproct longitudinally divided into a pair of sclerites, and female sternite 8

reduced to pair of elongate triangular sclerites. The Archiceroptera mahukani species group is

supported by the following characters: dorsocentral setae in 3 or more pairs, anterior katepisternal

seta extremely reduced or absent, and scutellum with 2 or more setulae near basal seta. The

incomplete linkage between female tergite 7 and 8 supports its treatment as intermediate between

the A. addenda group and the A. ternum group. The A. ternum group is well supported by the

following synapomorphies: female tergite 7 projecting acutely to and fused with tergite 8 (e.g., Fig.

6.32B; secondarily broadened in a few species), lateral halves of epiproct with small lobes on

anteromedial corner, and female sternite 8 with lateral sclerites medially articulating. The A.

brevivilla species group is a well supported subgroup of the A. ternum species group based on the

synapomorphic reduction of the mid tibial chaetotaxy, reduction of the male cerci and several

female genitalic characters.

Archiceroptera megacercus and A. paracercus were recovered together and share a

uniquely swollen dorsal margin of the postgonite along with extremely acuminate male cercus. Both

species occur in Costa Rica and Ecuador. These two species were initially considered to be related

to the Andean clade composed of A. bisetosus, A. basilia and A. bilobata, as they all have the female

tergite 7 medially desclerotized and the same mid tibial chaetotaxy (a single strong anterodorsal seta

and single strong posterodorsal seta near the midlength), but these two clades were recovered

separately. The elongation of the epiproct of A. megacercus and A. paracercus could be considered

an intermediate stage between the elongated anterior portion of the epiproct of the A. bisetosus

group and the anteriorly rounded epiproct of the rest of Archiceroptera.

6.6 Key to the species of Archiceroptera Papp

6.7 Species Descriptions

6.7.1 Archiceroptera addenda species group

The A. addenda species group is apparently the sister group to the rest of Archiceroptera, and is

characterized by derived female terminalia (epiproct medially divided, tergite 8 is tripartite). It

includes three newly described species: A. addenda, A. crenulata and A. triclavus. Members of this

species group can be recognized in having 3–4 median anterodorsal and 3–4 median posterodorsal

setae, a strong costagial seta, a secondary sclerite posterior to the male sternite 5, and a strongly

sclerotized distiphallus. The females tergite 8 and the epiproct are both plesiomorphic for

Archiceroptera; the medial part of tergite 8 is absent or poorly developed, and the epiproct is either

entire (A. crenulata and A. triclavus) or only narrowly divided (A. addenda).

Type Material: Holotype (male, debu01077561): ECUADOR: Pichincha: Río Palenque Stn., 47

km S Santo Domingo, light, 1 May 1987, B. Brown (QCAZ).

Comments: Archiceroptera browni has a number of characters that are unique within

Archiceroptera, the most obvious being the absence of ocelli. Ocellar reduction occurs in several

different limosinine clades (e.g., Aptilotella, Howickia), and is usually associated with loss of flight

(see Luk & Marshal 2014) and an associated shift to a terricolous habit; the well-developed wings of

A. browni are not consistent with that pattern. The collection of the holotype at a light trap might be

reflective of nocturnal habits. Also unique in this species is the reduced size of the thoracic

chaetotaxy compared with other Archiceroptera and the reduced epandrial process, which is

- 150 -

relatively distinct in all other members of the larger Archiceroptera-group (with the exception of A.

venezolana). Both of these are apparently apomorphic.

Etymology: This species is a patronym for Dr. Brian Brown, the collector of the type specimen and

previous graduate student at Guelph.

Comments: Papp (1977) discussed the differences between A. mahukani and A. venezolana, giving

support of their differences using number of interfrontal setae, dorsocentral setae, extrascutellar

setae, and tibial chaetotaxy. As he only had the holotype of A. mahukani and Richards’ (1963)

limited description, he was unable to examine the extent of the variation within either species; the

tibial chaetotaxy and interfrontal setae are not useful to separate the two species. The distributions

of the two species appear to be allopatric, with A. venezolana occuring in the northern half of South

America and A. mahukani occuring farther to the south (Bolivia and Paraguay). The male internal

genitalia remain unknown.

6.7.3 Archiceroptera ternum-species group

Species from this group are known from the USA south to Argentina. This group includes

all Archiceroptera species outside the two basal clades (A. addenda and A. mahukani species

groups). All 23 species in this group are here newly described. Members of this group can be

recognized by the combination of a distinct dorsal basal seta, female tergite 7 fused laterally with

tergite 8, and female sternite 8 reduced to a pair of lateral triangular sclerites that narrowly meet

medially. The A. brevivilla species subgroup is a derived species group within the A. ternum group

that has a reduced mid tibial chaetotaxy.

- 156 -

Archiceroptera ternum species group description:

Head: Frons with 4–7 interfrontal seta. Gena with 2 strong anterior setae and additional smaller

posterior setae.

Thorax: Prescutellar dorsocentral seta strong. Acrostichal setulae in 4-10 rows between prescutellar

dorsocentrals. Anterior katepisternal seta absent or present. Scutellum with 1 setulae near basal seta

(A. bilobata) or without setulae (all other species).

Legs: Mid tibia with dorsal basal seta, 1–3 median anterodorsal, and 1–4 median posterodorsal

setae; strong predistal anterodorsal present; predistal dorsal present or absent; distal posterodorsal

setae present or absent; male with or without ventral comb; midventral seta present in females and

some males. Mid basitarsus with basal posteroventral setae variable in length compared with distal

setae. Hind tibia dorsally variable (usually simple, but 1–7 dorsal setae and/or preapical seta present

in some species).

Wings: Costa with 2 strong costagial setae; dorsal seta usually longer. Cell dm with small CuA1 stub

vein present or absent.

Male abdomen: Sternite 4 posteromedially usually entire (emarginate in some species). Sternite 5

variable (usually posterior margin medially emarginate). Transverse portion of sternite 6 nearly

straight to strongly arcuate. Surstylus variable. Cercus variable (triangular to basally ovoid with

apical portion narrowed). Distiphallus with acrophallus largely membranous.

of tergite 8. Tergite 8 tripartite, with medial sclerite well sclerotized. Epiproct medially

desclerotized into paired sclerites; with scattered setulae. Cercus variable (often tear-drop shaped)

with flattened apical seta with small, flattened preapical seta appressed to base of apical seta.

Sternite 7 posteriorly usually rounded (emarginate in some species). Sternite 8 medially divided into

pair of elongate triangular sclerites that narrowly meet medially. Spermatheca shape variable, with

swelling at duct junction; paired spermathecae with stems extremely short or obsolete.

Male Abdomen (Fig. 6.19): Sternite 4 posteriorly entire. Sternite 5 posteromedially with diamond-

shaped emargination that extends to basal ¼ of sternite; emargination flanked by acute

posteromedially-directed processes (which may have small apical crenulations present). Transverse

portion of sternite 6 narrowly, but strongly, arcuate; right lateral portion recurved and fused with

quadrate sclerite. Synsternite 6+7 with narrowly rounded medially projecting process, with

triangular sclerite immediately distal to tip. Cercus basal 1/3 triangular with strong distinct seta;

apical 2/3 narrowed slightly and medially curved at apical 1/3. Surstylus (in lateral view) with small

anterior lobe with short, rounded process; posterior portion with 14–16 setae along posterior

surface. Postgonite basal ½ quadrate with rounded ‘heel’; apical 1/2 acuminate with upper surface

flat. Distiphallus: dorsal sclerite with apical ¼ extending beyond apex; acrophallus with broadly

rounded dorsolateral flaps and with large, triangular ventral portion.

Female Abdomen (Fig. 6.20): Tergite 7 posteromedially broadly sinuate; posterolaterally narrowly

fused to tergite 8. Tergite 8 with lateral sclerites broadly rounded; medial sclerite broadly triangular.

Epiproct with lateral sclerites anterolaterally rounded. Cercus basally quadrate; flattened apical setae

Comments: The enlarged sclerite at the apex of the medially projecting process on the left side of

synsternite 6+7 has some resemblance to the sclerites found in the A. addenda group. One paratype

has a fungal growth (Laboulbeniales) in the middle of sternite 5 (Fig. 6.19 A–B).

Etymology: The species epithet is the Latin for “diamond” in reference to the diamond shape

emargination of the male sternite 5

Comments: There appears to be some subtle allometric variation between larger and smaller A.

barberi males, but this appears to be variation between individuals and not suggestive of cryptic

species.

Comments: This is a widespread species that has been collected at a variety of baits. A series from

Panama has an eye:genal height ratio of 1.7:1, much lower than other members of this species (2:1),

but no other morphological differences suggest that the Panamanian material is distinct.

Etymology: The species epithet is from the Latin for pinch, referring to the appearance of the

posterior margin of the male sternite 5.

Comments: The surstylus of A. megavilla is similar to both A. cobolorum, from which it can be

easily separated by the mid tibial chaetotaxy, and A. braziliensis, which has a distinctly different

sternite 5.

Etymology: The species epithet refers to the large finger-like projection on the male surstylus.

6.8 Discussion

Archiceroptera is almost entirely Neotropical, with a handful of collections from the

Nearctic. Most study material came from Central America, Ecuador, and Venezuela, where there

have been numerous directed efforts to sample dung associated insects. The distribution of all study

material of Archiceroptera (Fig. 6.64D) shows a tropical distribution, with northern Argentina the

southern-most limit of the genus. The absence of Archiceroptera in material from numerous

collecting efforts from Chile and Argentina in DEBU, including those collected with dung traps,

supports this tropical distribution. Limited records from west of the Andes and Nearctic parts of

Mexico also suggests that mountains are significant barriers for this group, with only a few species

occurring at high elevation sites. The morphologically unique clade formed by A.bisetosus, A.

basilia and A. bilobata has a unique distribution within Archiceroptera as all three species are

associated with high elevation sites in Ecuador and Peru. Although the major diversity of

Archiceroptera now appears to be documented, there may still be remaining species to be

discovered, especially within the clades that occur in higher elevations (e.g., the A. basilia clade).

The most significant contribution that might be made to Archiceroptera is additional material from

eastern South America. Based on the novelty rate of material collected from French Guiana for

general unbaited pan traps, it is possible another 5-10 undescribed species remain from this area.

Contributions can also be made with adequately preserved material for molecular analysis.

Additional sequences of other Archiceroptera species, especially of the clades of the A. ternum

group that were not represented here, may help ellucidate the relationships and determine if the

differences from the morphological analysis are sampling artifacts.

CHAPTER 7 – SUMMARY

A preliminary estimate of the relationships within the EPG is provided on the basis of the morphological

phylogeny. The Archiceroptera genus complex was not recovered as monophyletic in the morphological analysis,

instead resolving into four distinct clades within the EPG. The EPG is maintained here as a monophyletic group,

based on the synapomorphic epandrial process and mid tibial chaetotaxy, but further morphological and molecular

studies are needed to examine the relationships with other Limosininae genera. The molecular analysis of the

Limosininae did not provide any useful resolution to potential outgroups for the EPG or strong support for any

relationships between EPG genera. A narrower analysis of only Archiceroptera sequences supports the

morphological treatment of brevivilla and ternum groups within Archiceroptera, along with the treatment of the

extension (addenda) group as a basal clade to the rest of Archiceroptera.

Archiceroptera and Rudolfina are redefined, Pectinosina is described, and 39 new species are described in

these three genera. The revisions of Archiceroptera, Rudolfina and Pectinosina provide keys, descriptions and

illustrations of all the described species. Archiceroptera is primarily Neotropical, now contains 29 described species

and is treated in a clade that also includes Pectinosina and Robustagramma. Pectinosina is also largely Neotropical,

and includes only two described species. Rudolfina is largely Nearctic, now contains 13 described species, and is

treated in a clade that also includes Pterogramma, Aptilotella, Bromeloecia, and Bitheca, along with the sororcula

and enigmata groups. The sororcula/enigmata clade remains undescribed, but preliminary work on the group

suggests there are ~10 species.
