Bekchiev, Rostislav & Hlaváč, Peter, 2019, Description of new species of Pseudamaurops Jeannel, 1948 (Coleoptera: Staphylinidae: Pselaphinae) from Greece and North Macedonia, Zootaxa 4688 (3), pp. 399-406 : 403-405

Pseudamaurops tymficus sp. n.

( Figs 2 d–3d)

Material studied: Holotype, 1 ♂, (p) NW GRECE [sic, Greece]— Tymfi mts. , Vikos n. p. [national park] 1800m at snow, Papingo env., 3.6.2008, Rudolf Kmeco leg. ( NMPC).

Description. Body slightly shiny, reddish-brown, covered with long golden setae, pubescence sparse on head, pronotum, and disc of elytra and abdomen, dense on sides of elytra and abdomen; legs, antennae, and maxillary palpi slightly lighter, length 2.61 mm; maximum width of elytra 0.75 mm. Head slightly wider than long, eyes composed of six ommatidia located around large, acute ocular spine on each side; clypeus large, prominent, rounded; frons with large, deep, transversely oval excavation, vertex flat, with well-defined lateral and median carinae, lateral carinae remote from antennal tubercles, median carina remote from posterior margin of frontal excavation, both reaching posterior margin of head capsule, vertexal pits separated, distant from lateral and median carinae; surface between carinae almost glabrous, smooth; antennae ( Fig. 2d ) relatively short and robust, 1.11 mm long, scape cylindrical, about 1.5 times as long as wide, antennomeres II–VII elongate, pedicel 1.25 times longer than III, III–V subequal, VI, VII and IX about same length, slightly shorter than V and slightly longer than VIII, antennomeres VIII–X transverse, VIII about 1.15 times as wide as long, IX and X about 1.33 times as wide as long, both symmetrical, lacking modifications, terminal antennomere symmetrical, about 1.4 times as long as wide, with apical, shallow, oval excavation. Pronotum slightly longer than wide, about as long as head, median antebasal and lateral foveae well-defined, well-separated by long lateral carinae that are remote from base of pronotum and almost reaching anterior pronotal margin, lateral carinae with small spine at level of lateral fovea, median fovea connected to base of pronotum by short median carina that extends to base of pronotum. Elytra simple, 1.3 times as long as wide and 1.3 times as long as abdomen, widest slightly behind middle, each elytron with two well-defined antebasal foveae, sutural striae almost entire, weakly-defined in posterior fifth. Abdomen about as wide as elytra, first visible tergite (IV) large, basal carinae reaching basal fifth of its length, their distance 0.28 of basal width of its width. Legs short and robust, simple, lacking spines or spurs. Aedeagus 0.42 mm long ( Figs 3d ).

Sexual dimorphism. Females unknown.

Etomology. Named after the type locality, Tymfi mountains in Ipiros.

Differential diagnosis. P. tymficus is readily separated from its congeners by the male mesofemora lacking spines, antennomeres IX and X are strongly transverse, and the pronotum has long lateral parallel carinae and a short median carina.

Distribution. Greece (Ipiros)
