INTRODUCTION Small mammals remain poorly known in the Afrotropics (Kingdon et al., 2013), despite this being one of the most diverse regions of the world for mammals (Burgin et al., 2018). Indeed, it has been predicted that a greater number of mammal species remain to be described in Africa than on any other continent (Fisher et al., 2018). The number of new bat taxa recognized in sub-Saharan Africa con- tinues to rise, with 33 species having been described or elevated to species rank in the 30 years from 1988 to 2018 excluding those described from Madagascar and other offshore islands (Hoffmann et al., 2009; Taylor et al., 2018). Many of the newly described taxa are cryptic species, not easily distinguishable based on external characteristics (Monadjem et al., 2013b). The genus Miniopterus appears to be particularly rich in cryptic species, clearly demonstrated by the rapid increase in the number of recognized species since the appli- cation of molecular techniques to systematic studies of this group (Goodman et al., 2007, 2009). In 2005, just four species of Miniopterus were recognized on Madagascar (Simmons, 2005); within 10 years that number had risen to 12 species (Christidis et al., 2014; Goodman et al., 2015).

INTRODUCTION

Small mammals remain poorly known in theAfrotropics (Kingdon et al., 2013), despite thisbeing one of the most diverse regions of the worldfor mammals (Burgin et al., 2018). Indeed, it hasbeen predicted that a greater number of mammalspecies remain to be described in Africa than on anyother continent (Fisher et al., 2018). The number ofnew bat taxa recognized in sub-Saharan Africa con-tinues to rise, with 33 species having been describedor elevated to species rank in the 30 years from 1988to 2018 excluding those described from Madagascarand other offshore islands (Hoffmann et al., 2009;Taylor et al., 2018).

Species richness in the genus Miniopterus has been greatly under-reported, with a large number of taxa having been discovered anddescribed in the past two decades. Using molecular, standard morphometrics and acoustic data, we present evidence for the existenceof a new species in Mozambique and neighbouring Malawi. Based on cytochrome b (cyt b) and cytochrome oxidase I (COI), thenew species is sister to M. minor, from which it is readily distinguishable by its larger size (including non-overlapping forearmmeasurements, allowing separation in the field). It is distinguishable from sympatric M. mossambicus, itself a newly described taxon from Mozambique, by forearm measurements and a peach-orange wash to the skin around the eyes. In external appearance,it is most similar to M. fraterculus, from which it is only reliably identifiable by multivariate analysis of craniodental features and by a genetic distance of 6.4% in the cyt b gene; the two species also occupy widely differing geographic ranges. The type locality of the new species is Mount Gorongosa, and all known records are from large mountains in central and northernMozambique and southern Malawi. Further research is required to establish its geographic range and understand its basic ecology.Considering its relatively restricted distribution to threatened montane habitats, we suggest that its global conservation status beurgently assessed.

recently described (Monadjem et al., 2013a, 2019;Puechmaille et al., 2014). This is unlikely to be dueto any inherent lack of diversity for biogeographicreasons. On a single mountain in Malawi, south-cen-tral Africa, four Miniopterus species were reported,but none of them could be named with certainty(Curran et al., 2012); this compares well with thesituation in Madagascar where up to four species ofMiniopterus may co-occur (Goodman et al., 2009).Indeed, a recent phylogeny based on a multilocusapproach suggested the existence of up to five unde-scribed taxa in Africa (Demos et al., 2019).

The taxonomy of Miniopterus in West Africa hasrecently been investigated, where currently two spe -cies occur, both endemic to the Upper and LowerGuinea forest block (Monadjem et al., 2019). NorthAfrica also has two species, one of which was re-cently described as a cryptic species (Puechmaille etal., 2014). The situation in East Africa is compli-cated by the lack of recently published surveys, butat least one new species, resulting from the elevationof an existing taxon to specific status, has been un-covered by molecular analysis (Šrámek et al., 2013).Furthermore, the recent multi-locus phylogeny referred to above, demonstrated that nine of the 13 recognized clades of African Miniopterus occurin East Africa (Demos et al., 2019).

Three species have been traditionally recognizedin southern Africa south of the Zambezi River, dif-ferentiated mostly on size (Stoffberg et al., 2004)from smallest to largest: M. fraterculus, M. nata-lensis and M. inflatus (Monadjem et al., 2010b). A fourth species, M. mossambicus, was recently de-scribed from northern Mozambique but was thoughtto extend further south into central Mozambique(Monadjem et al., 2013a) and represents the small-est Miniopterus species in the region. These fourspecies are not easily identifiable in the field but areclearly distinguishable on cranial and genetic char-acteristics (Miller-Butterworth et al., 2005; Mona -djem et al., 2013a), underscoring the fact that cryp-tic species abound in this genus. Adding to theconfusion is the possibility of a fifth species occur-ring in this region, another diminutive species, M. mi nor which is currently known from Tanzania,Central African Republic and Democratic Republicof Congo (Monadjem et al., 2010b), with the west-ern subspecies occidentalis probably a separatespecies (Juste and Ibañez, 1992).

Recent bat surveys on Mount Gorongosarecorded a small Miniopterus species on the mid-slopes of the mountain. Here, we show that this an-imal represents an undescribed taxon, with a larger

distribution closely associated with the high moun-tains of Mozambique and Malawi. Recent studiespoint to this region having a large number of en-demic species (Bayliss et al., 2014; Conradie et al.,2016), many with small distributions centered onone or a few mountains such as the recently de-scribed gecko Afroedura gorongosa (Branch et al.,2017).

MATERIALS AND METHODS

Samples

Bats were captured at Mount Gorongosa (18.48°S, 34.04°E,elevation 920 m above sea level [a.s.l.]) (Fig. 1), and depositedin either the Durban Natural Science Museum, Durban, SouthAfrica (permit information: N/Ref.133/MHN/E.27/2015; 13/1/1/30/2/0-215/08/005246; OP 3321/2015; OP3318/215) or theEO Wilson Laboratory based in Chitengo, Gorongosa NationalPark, Mozambique (permits PNG/DSCi/Cll/2015, PNG/DSCi/C8/2015). Tissue samples were taken from the pectoral musclesof collected specimens.

Genomic DNA Isolation, Amplification andSequencing

Genomic DNA was isolated from tissue samples using theQIAamp DNA Investigator Kit (Qiagen, Germany). Tissue sam-ples were cut with a scalpel blade and were subsequently di-gested overnight (20–22 hours) in Proteinase K and ATL tissuelysis buffer. Following digestion, DNA was isolated accordingto the manufacturer’s instructions. Primers were used to amplifyregions of the mitochondrial genes cytochrome oxidase I (COI,520 bp) and cytochrome b (cyt b, 1140 bp). The COI gene wasamplified using the universal conservative primers BatL5310and R6036R (Hebert et al., 2003). In addition, L14724 andH15915 (Xiao et al., 2001) and L15162 and H15915 (Irwin etal., 1991) were used to amplify a region of cyt b. Amplificationof the respective gene regions was carried out in separate PCRreactions consisting of 1 × DreamTaq Green PCR Master Mix,0.4 µM of each primer, and approximately 20 ng template DNAin a total volume of 20 µl. The temperature profile was as fol-lows: an initial denaturation at 95°C for 2 min, 35 cycles of95°C for 30 s, 55°C for 30 s, and 72°C for 1 min, followed by a final extension at 72°C for 10 min. Successful PCR productswere purified with Exonuclease I and FastAP (Thermo FisherScientific Inc.). Gene fragments were sequenced in both direc-tions using the BigDye Terminator v3.1 Cycle Sequencing Kitand visualized on a 3500 Genetic Analyzer (Applied Biosys -tems). Sequence chromatograms were viewed using SequencingAnalysis Software v.6.0 (ThermoFisher Scientific).

Phylogenetic Analysis

The dataset consisted of 37 cyt b sequences (Table 1), whichcontained 35 reference sequences representing the speciesMiniopterus fraterculus Thomas and Schwann, 1906; M. fuligi-nosus (Hodgson, 1835), M. gleni Peterson, Eger and Mitchell,1995, M. griveaudi Harrison, 1959, M. cf. inflatus, M. macroc-neme Revilliod, 1914, M. majori Thomas, 1906, M. manavi

Lastly, two field isolate sequen-ces (JAG444, JAG445) generated by South African NationalBio diversity Institute (SANBI), and Chaerephon pumilus(Cretzs ch mar, 1826) and Scotophilus dinganii (A. Smith, 1833)were used as outgroups.

All sequences were manually trimmed and aligned withMUSCLE (Edgar, 2004) using default parameters in MEGA 7version 7.0.26 (Kumar et al., 2016). The best model for se-quence evolution, General Time Reversible (GTR) model withGamma distribution (G = 1.53) and Invariable sites (I = 0.58),was determined under the Bayesian Information Criterion (BIC)using the model test function incorporated in MEGA7.Phylogenetic relationships were evaluated using the ML and NJmethod implemented in MEGA 7 (Kumar et al., 2016). To esti-mate support for internal nodes, 1000 bootstrap replicationswere run using the same program (Felsenstein, 1985; Kumar etal., 2016). Sequence variation and average sequence divergencewere determined by group mean distances using the p-distancesubstitution model in MEGA 7 (Kumar et al., 2016). Aligned se-quences were exported to a Fasta file format for BayesianInference (BI) analysis in Mr Bayes (v3.2.7). Markov Chain

Monte Carlo (MCMC) analysis was conducted using the above mentioned model parameters (GTR G+I: nst = 6; rates =invgamma), default parameters for the estimations of priors, onecold and three heated chains, and run for 100,000 generationssampled every 100 generations with a burn in of 25%. By de-fault, two simulations are conducted at the same time. A stoprule parameter using the average standard deviation of split fre-quencies (SD) between the two simulations was also imple-mented to stop analysis when the threshold (SD = 0.01) wasreached, which occurred at 750,000 generations. An SD value of0.05 is the default value used as a diagnostic determinant ofconvergence of the two simulations. An SD value approaching0 indicates that the two simulations become increasingly simi-lar. The generated tree file was converted to the Newick formatusing FigTree (v1.4.3) and annotated in MEGA7. Molecularclock analysis was conducted in BEAST 1.7.4 (Drummond andRambaut, 2007; Drummond et al., 2012) following methods de-scribed in Christidis et al. (2014).

the basisphenoid-basioccipital suture, were included in thisstudy. We examined type specimens in the BMNH and FMNH,which included: M. fraterculus (BMNH 1905.5.7.18), M. infla-tus (BMNH 1903.2.4.8, holotype), M. natalensis (BMNH1848.6.12.19, holotype), and M. mossambicus (FMNH 213651,holotype).

The following standard external measurements were taken inthe field: total body length, tail length, ear length, and forearmlength. Forearm length was taken with callipers to the closest 0.1mm; all other measurements were at an accuracy of 1 mm. Bodymass was taken with a Pesola spring balance to the nearest 1 g.

Eight cranial measurements were taken with callipers fol-lowing Monadjem et al. (2013b) that included: greatest skulllength (GSKL), from the posterior-most point of the cranium tothe anterior-most point of the incisors; condylo-incisive length(CIL), from the occipital condyles to the anterior-most point ofthe incisors; greatest zygomatic breadth (ZYGO), the greatestwidth across the zygomatic arches; postorbital width (POB),narrowest dorsal width posterior to the postorbital constriction

of the cranium; greatest mastoid breadth (MAST), greatestbreadth of cranium at mastoid processes; greatest braincasewidth (GBW), lateral braincase width taken posterior to the pos-terior insertion of the zygomatic arches; lachrymal width (LW),greatest width across rostrum at lachrymal projections; andgreatest mandible length (MAND), taken from the posterior-most point of the condylar processes to the anterior-most pointof the incisors.

Eight dental measurements were taken with callipers to theclosest 0.01 mm following Monadjem et al. (2013b) that in-cluded: width across the third molars (M3–M3), taken across theouter-most point of the alveoli of the 3rd molars; completeupper canine-molar tooth row (C–M3), taken from the anterior-most point of the alveolus of the canine to the posterior-mostpoint of the 3rd molar; complete upper tooth row (I1–M3), takenfrom the anterior-most point of the alveolus of the first incisorto the posterior-most point of the 3rd molar; complete uppermolar tooth row (UPMOLS), taken from the anterior-most pointof the alveolus of the anterior premolar to the posterior-most

Tooth abbreviations are as follows: I = incisor, C = ca-nine, P = premolar, M = molar; with upper teeth presented inupper case and lower teeth in lower case.

A principal components analysis (PCA) of standardized val-ues of the above craniodental measurements was conducted onthe variance-covariance matrix in package ‘vegan’ (Oksanen etal., 2007) in R version 3.4.4 (R Core Team, 2019), to comparethe morphology of the various taxa measured in this study. Dueto the lack of sexual dimorphism (Monadjem et al., 2010b), thesexes were combined for all analyses.

Acoustic Analysis

Echolocation calls were recorded from hand-released indi-viduals and individuals flying in a large free-flight tent using a full-spectrum recorder Pettersson D1000X at a sampling fre-quency of 300 kHz. Calls were analysed using BatSound Prosoftware (version 3.20 — Pettersson Elektronik, Uppsala,Sweden), and the peak frequency was recorded (Monadjem etal., 2010b).

RESULTS

Molecular Analyses

The phylogenies based on cyt b and COI genesproduced similar tree topologies for both Bayes-ian and neighbor-joining methods (Fig. 2). Basalnodes are poorly supported. However, several clades are apparent. Miniopterus natalensis is sisterto the Malagasy species; embedded within the latter is M. mossambicus. Miniopterus cf. inflatus(from Malawi) is sister to a clade that includes M. fraterculus, M. minor, and the new species from Mount Gorongosa Miniopterus sp. nov. The

new species is sister to M. minor. Genetic distancesbetween the various species mentioned in this phy-logeny were 5–16% (Table 3). The new species M. sp. nov. differs from M. minor between 4.1 and5.7% (average = 4.9%). Divergence based on theBeast analysis (Fig. 3) between M. minor and M. sp. nov. is estimated to have occurred between 1 to 2 Mya.

Morphometric Analyses

A PCA ordination based on craniodental meas-urements showed that southern African Miniopterusspecies mostly occupied distinct morphospace (Fig.4A). The first two principal components accountedfor 92% of the variation, and hence are shown here.The first principal component represented a size gra-dient with highest loadings on GSKL and ZYGO(0.313 and 0.311, respectively), with all other load-ings also being positively associated with it (Table4). As a result, the species are distributed along thisaxis based on size with the smallest species (M. minor) occurring on the left and the largestspecies (M. cf. inflatus) on the right of the ordina-tion. The second principal component representeddifferences in shape with high positive and nega-tive loadings, the largest being with POS and C–M3 (0.440 and -0.493, respectively) (Table 4).Similar sized species were typically separated onthis axis such as M. fraterculus and M. mossambicus(Fig. 4A). Only two species did not separate in mor-phospace: M. mossambicus and the new species M. sp. nov. which overlapped somewhat. How-ever, when these two species (M. mossambicus and M. sp. nov.) were considered separately, theyoccupied non-overlapping areas of morphospace(Fig. 4B), illustrating their distinctiveness in cranialand dental features. Based on these molecular and

Cryptic diversity in southern African Miniopterus 7

morphometric data, we describe a new species ofMiniopterus for Africa.

DESCRIPTION OF NEW SPECIES

Family Miniopteridae Dobson 1875

Genus Miniopterus Bonaparte 1837

Miniopterus wilsoni sp. nov.Wilson’s Long-fingered Bat

HolotypeJAG 444, an adult male, was collected by Jen

Guyton on 22 April 2018, and deposited into the col-lections of the E.O. Wilson Laboratory BiodiversityLaboratory at Chitengo, Gorongosa National Park,Mozambique. The specimen was preserved in 70%ethanol. The skull has been extracted and cleaned.External features of the holotype are illustrated inFig. 5A and its skull in Fig. 6.

Type localityMozambique, Sofala Province, Gorongosa

National Park, Mount Gorongosa (Fig. 1). The batwas collected on 22 April 2018 on Mount Goron -gosa (18.48309°S, 34.04485°W) at 920 m a.s.l. It was netted over a river in a montane riverine for-est fragment adjacent to montane grassland and agri-cultural fields.

ParatypesA single female (JAG 445) was also captured and

collected on the same day at the same site and de-posited into the collections of the E.O. Wilson Labo -ratory Zoological Museum. Photograph of the para -type is illustrated in Fig. 5B.

Cryptic diversity in southern African Miniopterus 9

EtymologyThis species is named after Edward O. Wilson

who has supported and facilitated biodiversity re-search at Gorongosa National Park over the pastdecade.

DiagnosisThis is a small-sized Miniopterus currently con-

firmed by molecular analysis from central Mozam -bique, and by morphometric analysis from northernMozambique and southern Malawi. Mean forearmlength for the species is 44.1 mm (n = 8). The smallsize of this bat readily distinguishes it from medium-and large-sized Miniopterus in Africa, particularlythe M. inflatus/M. africanus and the M. natalensisgroups (Happold 2013a, 2013b). In general, M. wil -soni sp. nov. is similar in size to M. fraterculus andM. mossambicus, but significantly larger than thetiny M. minor (Tables 5 and 6); however, in multi-dimensional morphospace based on craniodentalmeasurements, it occupies a distinct morphospace(Fig. 4A and 4B). Furthermore, it can be readily dis-tinguished from sympatric M. mossambicus by fore-arm length (FA > 43 mm in M. wilsoni sp. nov., < 43mm in M. mossambicus); the two species do notoverlap in this measurement (Table 3). Finally, allspecimens of M. wilsoni sp. nov. that have been ex-amined, have a peach-orange wash to the skin of theface under the fur around the eyes, which is absentin M. mossambicus. The only other southern AfricanMiniopterus species with this feature that we areaware of is M. fraterculus, which has a yellowishwash. Morphologically, M. wilsoni sp. nov. most resembles M. fraterculus, from which it differs onmolecular grounds (K2P pairwise genetic distance

6.4%) and on being larger in dental features (Table6). The two species also occupy non-overlappinggeographic ranges. Based on the cyt b gene, the sis-ter species to M. wilsoni sp. nov. is M. minor, fromwhich it can be readily distinguished by its larger,non-overlapping size (forearm length) and mostcraniodental features (Tables 5 and 6).

DescriptionExternal characters. — Miniopterus wilsoni sp.

nov. has the typical features characteristic of thegenus including a rounded head, an elongated sec-ond phalanx of the third digit, rounded ears, and a relatively long and straight tragus (Fig. 5). The tailis almost exactly half that of the total length. Thepelage is medium brown above and only slightlypaler below. Individual hairs are unicoloured. Thespecies is small-sized for a Miniopterus, beinglarger than M. minor, M. occidentalis and M. mos -sam bicus and smaller than M. natalensis and M. cf.inflatus; it does not overlap with any of these fourspecies based on forearm length (Table 3). How-ever, it is similar in size and colouring to that of M. fraterculus. It shares the distinct wash across the face but is peach-orange in colour comparedwith a yellowish wash in M. fraterculus (Fig. 5B).How ever, it is not known whether this is a character specific to these two species, nor whether all indi-viduals of these two species have it. Miniopte-rus wilsoni sp. nov. has a tragus that is mostly equal-ly wide along its entire length, except for a slightconstriction or inflection near its midpoint (Fig. 5B).Unlike M. mossambicus, the tragus of M. wilsoni sp.nov. lacks the slightly constricted base (also evidentin M. fraterculus) and has a rounded tip that is

broader than the rest of the tragus (Monadjem et al., 2013a).

Craniodental characters. — The skull is gracilefor a Miniopterus species. The rostrum is broad, andthe braincase is rounded and high, typical for thegenus of Miniopterus. The dentition of M. wilsonisp. nov. is I 2/3, C 1/1, P 2/3, M 3/3, which is typicalof the genus. In the upper tooth row, the inner inci-sor is larger than the outer one, and the anterior pre-molar is relatively well developed (Fig. 7). The cra-nial and dental measurements of the holotypecompared with a sample of other southern AfricanMiniopterus species are shown in Table 6.

DistributionCurrently, the only genetically confirmed speci-

mens of this new species come from Mount Goron -gosa, central Mozambique. However, a number ofspecimens collected in northern Mozambique andsouthern Malawi without genetic identification aremorphologically similar and therefore they arelikely to be conspecific with M. wilsoni sp. nov. Allthese specimens were collected on sizeable moun-tains, including Mount Gorongosa (elevation: 1,863m a.s.l.), Mount Namuli (2,419 m a.s.l.), and MountMabu (> 1,600 m a.s.l.) in Mozambique, and ZombaMassif (2,047 m a.s.l.) in Malawi (Fig. 1).

BiologyLittle is known about the biology of this species. It

appears to be associated with montane habitats, withmost records taken from around 1,000 m a.s.l. Basedon our limited sampling, it appears to be the onlyMiniopterus species at higher elevations (> 900 m) onMount Gorongosa. However, two other Miniopterus

species are widely distributed within GorongosaNational Park at lower elevations (< 300 m a.s.l.),M. mossambicus and M. cf. inflatus.

Echolocation calls of specimens captured and re-leased at the same site as the holotype and paratype,and believed to represent the same species, hadmean peak frequency (± SD) of 56.8 kHz ± 0.96kHz (range: 56–58 kHz, n = 4) which is slightlyhigher than that reported for M. mossambicus fromMount Namuli (Monadjem et al., 2013a), howeverthe recordings reported for the latter species weretaken from a location that is now included in the dis-tribution of M. wilsoni sp. nov. and with a differentbat detector (Anabat). The peak frequency of two M. mossambicus in Gorongosa National Park were60 and 61 kHz, while a single individual of thelarger M. cf. inflatus had a peak frequency of 49kHz. Based on these limited recordings, it would ap-pear that the three species of Miniopterus in centralMozambique differ in their echolocation calls.

DISCUSSION

In this paper, we present new information on a population of Miniopterus from Mozambiqueshowing that it represents a new species to science.This is the second new Miniopterus species to be de-scribed from this country in the past decade and fol-lows a trend of new discoveries in Madagascar andWest Africa (Christidis et al., 2014; Goodman et al.,2015; Monadjem et al., 2019). Considering the re-cent phylogeny for Miniopterus by Demos et al.(2019), it would appear that these new species de-scriptions are just the tip of the iceberg, as predictedby Monadjem et al. (2013a).

The description of M. wilsoni sp. nov. brings thetotal number of Miniopterus species known fromMozambique to four (Monadjem et al., 2010a,2013a). Within Mozambique, these four species ap-pear to occupy different geographical regions orhabitats. Miniopterus wilsoni sp. nov. is only knownfrom large mountain ranges where it occurs at mid-and perhaps higher elevations. In contrast, M. mos -sambicus and M. cf. inflatus appear to occupy lowerelevations, whereas M. natalensis is only knownfrom the southern parts of the country. All fourspecies also occur beyond the borders of Mozam -bique: with M. natalensis and M. cf. inflatus wide-spread in the region to the south and west of thecountry (Monadjem et al., 2010b); M. mossambicusoccurs further north into Tanzania and Kenya(Demos et al., 2019); and, based on our morpholog-ical analyses, M. wilsoni sp. nov. appears to alsooccur at Zomba Massif, Malawi. Its distribution,however, is not yet fully known and it may occur atother mountains in the region such as MountMulanje (Curran et al., 2012) or perhaps west intoZambia.

Based on the cyt b gene, M. wilsoni sp. nov. ap-pears to have diverged from its closest living rela-tive, M. minor, over the past one to two millionyears. Divergence dates for Miniopterus speciesfrom other regions of continental African have notyet been reported, thwarting any attempts at recon-structing the biogeography of this genus on the con-tinent. However, in Madagascar, there was a pulse ofdiversification between 2–3 Mya, with some taxahaving diverged within the past million years(Christidis et al., 2014). The appearance of M. wil -soni sp. nov., therefore, fits in with the observedtrend of speciation in Malagasy Miniopterus.

It is worth noting that M. cf. inflatus needs nam-ing as it is not conspecific with M. inflatus from cen-tral Africa; in fact, these two taxa belong to differentclades (Monadjem et al., 2019). This species waspreviously thought to be widely distributed acrossAfrica, but recent genetic evidence suggests that it isrestricted to Cameroon and Gabon, although popula-tions in neighboring Congo, Democratic Republic ofCongo and Central African Republic may also referto this species. The West African population has a restricted distribution centered on Mount Nimba(Liberia/Guinea) and surrounding uplands (Mona -djem et al., 2019), while the systematics of the pop-ulations in southern and eastern Africa that werepreviously referred to as ‘M. inflatus’ needs resolv-ing. Furthermore, based on our morphometric analy-ses, M. minor minor from Tanzania is distinguishableS

from M. minor occidentalis from Central Afri-can Republic and the Democratic Republic ofCongo, a result mirroring that of Juste and Iba-ñez (1992), and suggesting that these two taxa mayrepresent separate species; this requires further investigation.

The newly described species, M. wilsoni sp. nov.,is only known from relatively high elevations on bigmountains where we assume that it is associatedwith forest edges. The type locality is from mid-elevation riparian forest on Mount Gorongosa whereincreased pressure on the remaining forest frag-ments comes from agriculture and timber harvesting(P. Naskrecki and J. Guyton, personal observation).Such pressure on mid- and high-elevation forests iswell-known on other mountains in the region(Dowsett-Lemaire, 2010; Curran et al., 2012; Bay -liss et al., 2014). Therefore, we suggest that theglobal conservation status of M. wilsoni sp. nov. beassessed without delay, as the chances of it being en-dangered are high.
