Assing, Volker, 2017, On Quedius coloratus FAUVEL, 1875 and allied species, with an appendix on Quedius species collected in Greece with subterranean pitfall traps, and a new synonymy (Coleoptera: Staphylinidae: Staphylininae), Linzer biologische Beiträge 49 (1), pp. 207-228 : 221-222

Quedius (Raphirus) carpathius nov.sp. (Figs 15, 20, 27, 40, 49, 56, 58, Map 1 )

T y p e m a t e r i a l: Holotype 3: "GR Karpathos, Olympos 250 m, Meybohm 27.4.2000 / Holotypus 3 Quedius carpathius sp. n., det. V. Assing 2017" (cAss) . Paratypes: 13: "GR Karpathos, Olympos Prof. Ilias, 450-700 m, Meybohm 27.4.2000 " (cAss) ; 13 [teneral]: "GR Karpathos, Umg. Olympos, 350 m, Meybohm 30.4.2000 " (cAss) ; 13: "GR Karpathos 440 m, Othos [35°33'N, 27°09'E], Meybohm 20.4.1999 " (cAss) ; 1♀: " Greece: Karpathos [13], N Olympos, E Avlona, 35°46'09''N, 27°11'13''E, 260 m, under stones, 26.XII.2015, V. Assing " (cAss) .

C o m m e n t: The female paratype was recorded as Q. coloratus by ASSING (2016a).

E t y m o l o g y: The specific epithet is an adjective derived from Carpathus, the Latin name for Karpathos.

D e s c r i p t i o n: Measurements (in mm) and ratios (range, arithmetic mean) (n = 5): TL: 9.1-10.0, 9.6; HL: 1.23-1.32, 1.27; HW: 1.46-1.58, 1.50; PL: 1.67-1.79, 173; PW: 1.76-1.95, 1.86; EL: 1.07-1.28, 1.15; HTiL: 1.37-1.53, 1.47; HTaL: 1.16-1.23, 1.19; ML: 1.21-1.28, 1.24; HW/HL: 1.18-1.19, 1.19; PW/HW: 1.21-1.27, 1.24; PL/PW: 0.89- 0.95, 0.93; EL/PL: 0.64-0.71, 0.67; HTiL/HTaL: 1.10-1.32, 1.27.

External (Fig. 15) and sexual characters similar to those of Q. hebes , except as follows:

Body on average smaller (see measurements; little overlap).

3: aedeagus (Figs 27, 40, 49, 56) distinctly smaller than in Q. hebes (see measuments ML and Fig. 58 ; no overlap); median lobe apically more acute and not curved dorsad in lateral view; paramere constricted medially.

♀: tergite X (Fig. 20) apically with conspicuously small posterior excision.

C o m p a r a t i v e n o t e s: Among the species with additional punctures near the posterior frontal puncture on the head and with more strongly dilated protarsomeres I-IV, Quedius carpathius is characterized by relatively small body size, a small pronotum, short tibiae, and particularly by the shape of the aedeagus (paramere constricted medially) and by the smaller posterior excision of the female tergite X.

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: Currently available evidence suggests that Q. carpathius is endemic to Karpathos ( Map 1 ). Previously, ten endemic species of Staphylinidae (three of them undescribed) belonging to eight genera were known to occur in this island ( ASSING 2016a). The type specimens were collected in five localities, four of them in the north of Karpathos, at altitudes between 250 and at least 450 m. The female paratype was found under a stone in a dry ruderal habitat. The remaining specimens may have been collected from under stones, too. One specimen taken at the end of April is teneral.
