Esser, Jens & R, Palaearctic, 2017, Two new species of Cryptophagus HERBST, 1792 (Coleoptera: Cryptophagidae) from China, Linzer biologische Beiträge 49 (2), pp. 1129-1132 : 1131-1132

Cryptophagus schuelkei nov.sp.

T y p e m a t e r i a l: Holotype 3: " China, N-Yunnan (C03-12), Zhongdian Co.: pass 28 km ESE Zhongdian, 3700-3750 m, 27°43.9’N; 98°58.2’E, leg. Schülke, 22.8.2003 " [cES].

Paratype: 1♀ with the same data than the holotype [cES].

E t y m o l o g y: The specific epithet points on Michael Schülke (Berlin), who collected all specimens of this species.

D e s c r i p t i o n: Male, hind wings absent, 2 mm. Reddish-brown, shining ( fig. 3 ). Eyes small but convex with only a small number of ommatidia. Pronotum 1,5 times broader than long, broadest before the middle tooth, margin strongly concave between anterior angles (callosities) and convex between middle tooth and posterior angles. Margin is forming a transparent lamella between posterior angles and the middle tooth, the outer margin is convex, the inner margin straight. Anterior callosities small, forming a hook-shaped tooth oriented backwards. Front margin straight, hind margin slightly rounded. Pronotum strongly and moderately dense punctate, surface convex, margin not depressed. Elytra elongate, oviform, with moderately long and more or less decumbent hairs. No humeral callus developed, with a longish callosity next to the suture. Elytra in the anterior third strongly but less dense punctate than on pronotum. Legs stout, tarsi five-segmented, posterior tarsi four-segmented (only in male), anterior tarsomeres 1-4 moderately widened (only in male). Antennae stout, club well developed, segments 1, 2, 4-8 moniliform, segment 1 and 2 broader than the remaining, segment 3 longer than broad, 9 and 10 transverse, 10 broader than 9, segment 11 oval and asymmetric. Parameres as in fig. 4

C o m m e n t Resembles to Cryptophagus puetzi nov.sp. ( fig. 1, 2 ) and is distinguishable by the shape of pronotum, parameres and distribution (Sichuan). C. schuelkei nov.sp. is also more shining. Cryptophagus hongguanus ESSER, 2017 (ESSER 2017b) differs in shape of pronotum and parameres more rounded. It is known from China, province Qinghai.
