INTRODUCTION

As presently circumscribed Platyderus Stephens,1828 includes 101 recognized species(www.carabidae.pro), with the vast majorityfound in South Mediterranean region. The greatpart of species occupy small, restr ictedgeographical ranges and occur mainly inundisturbed habitats in which they are seldomencountered. This suggests that manyundescribed forms await discovery. Based oncasual observation of material present incollections, the actual species–level diversity islikely to be two times this number or more.However, specimens of most species are veryrare in collections which makes impossible todevelop a full understanding of the inter andintraspecific variation. This paper will hopefullystimulate interest in the group and provide toolsfor identification to collectors and collectionsmanagers. Designations of new synonymies anddescriptions of new species are provided below.

The genus Platyderus was divided in speciesgoups by Jeanne (1996). Some of this grops arequite well delimited morphologicaly, other showswide variability and overlap each other. It is thecase of “ruficollis” and ”subcrenatus” groups,differ only by more or less punctured elytral striae.Here there is a proposition to unit them, and call“ruficollis-subcrenatus” group. This is the morecomplicated group with many new undescriedspecies, only few of this species are posible easydeterminate by external caracters, in the rest ofcase is necessary study of endofallus. Newspecies belongs to this group, characterisedbecause it has the middle dorsal pore of the elytrasituated on the third striae, with smooth orpunctured striae.

protuberances of endofallus are as followsAnichtchenko (2005): basal (B), dorsoapical(DA), ventroapical (VA), ventrolateral right(VLR), basolateral left (BLL), basolateral right(BLR), ventral (V) and sclerit (S).

Specimens were examined with Ziess DiscoveryV8 stereomicroscope. Habitus images have beenobtained using Sony A300 and Canon digitalcameras, CZM or Helicon Focus automontagesoftware, and processed on Adobe Photoshop.Measurements were taken using an ocularmicrometer as follows: body length, from anteriormargin of clypeus to apex of elytra along suture;length of pronotum, from anterior margin toposterior margin along midline; width ofpronotum, at widest point; length of elytra, frombase to apex along suture; and width of elytra, atwidest point.

Highresolution habitus images are available athttp://www.carabidae.pro “Carabidae of theWorld”.

The material from the following institutional andprivate collections has been examined:Universidad Complutense de Madrid (UCM);Museo Nacional de Ciencias Naturales de Madrid(MNCN); Universidad de Granada Collection(UGC); Collecion de Alexandre Anichtchenko,Tres Cantos (CAA); Collecion de Marcos Toribio,Tres Cantos (CMT); Collecion de Juan P.Zaballos, Madrid (JPZ); Collecion de Jose L.Zapata, Tres Cantos (JLZ).

Platyderus emblema Marseul, 1869= emblema Marseul, 1871 (Serrano, 2003; Lobl &Smetana, 2003; Lorenz, 2005)= marduk Anichtchenko, 2003 syn.n.

(Marseul, 1869: 388389; Serrano, 2003: 56;Anichtchenko, 2003; Anichtchenko, 2005: 108).Species was described by 2 specimens from“environs de Cordoue” [Cordoba vicinity](Marseul, 1869). For the long time was enigmaticand erronealy attributed to another taxón. Theerror is doubt to wrong translation from originaldescription, made J.M. de la Fuente (1927: 302) inhis keys to species. There was traduced fromDeutch: “elytral striae deep, densely punctured”instead of “elytral striae deep, smooth, intervalsdensely punctured”. Posteriorly this species waswrongly attributed to “varians” group of species(Jeanne, 1996: 409), because indeed in mountainsSierra Morena live one undescribed species,which using key to species of J.M. de la Fuenteeasy determined as P. emblema. One specimendetermined as P. emblema and deposited incollection of Joaquin Mateu (Barcelona), wasstudied by me before description of P. marduk, itwas from “varians” group, and is a new species,related to P. speleus Cobos, 1961.

Abdomen smooth.Structure of the internal middle lobe of the maleaedeagus is shown in (fig. 1719). ProtuberancesBLI and BLD asymmetrical, BLD much bigger.Basal protuberance not protruding.Etymology. Named after Cándido Bolívar Pieltain(1897–1976) who collected the specimens.Cándido Bolívar Pieltain was a prominent Spanishentomologist.Differencial diagnosis. This new species is welldistinct from any other Platyderus from Iberianpeninsule by numerous external morphologicalcaracters and endofallus structure. The newspecies is from “ruficollis-subcrenatus” groupof species and related to P. emblema and P.gazureki sp.n. by densely punctured intervals ofelytra. From P. emblema is easy distinguish byflat or slightly convex intervals of elytra andpunctured elytral striae, meanwhile in P. emblemaintervals are strongly concave and striae notpunctured. From P. gazureki sp.n. is distinguishby punctured ventral segments. Also is differentfrom both species by endofallus structure.
