Ocypus (Pseudocypus) imurai Smetana, 2005b , 308.

Type material. Holotype (male) and allotype (female): CHINA: Sichuan: " China: Sichuan, Hongyaxian , Near the summit of Wawu-shan , alt. 2600–2650 m, 25.V.–2.VI. 2004, Y. Imura & Y. Nagahata leg.” Holotype in the collection of the National Science Museum (Natural History), Tokyo; allotype in ASC.

Paratypes: CHINA: Sichuan: same data as holotype, 9 ♂♂, 13 ♀♀ in ASC .

Diagnosis. Ocypus imurai shares most character states with O. sericeomicans and differs from it mainly by the differently shaped aedoeagus and tergite 10 of female genital segment.

Description. Apex of abdomen becoming indefinitely paler in most specimens.

Male. Medioapical emargination of sternite 8 narrower, less deep and more arcuate. Sternite 9 of genital segment similar to that of O. sericeomicans , but narrower and longer, distinctly emarginate apically ( Fig. 45). Tergite 10 longer and narrower, arcuate apically ( Fig. 46). Aedoeagus ( Figs. 47–50) similar to that of O. sericeomicans , but markedly larger, with triangular apical portion wider, on face adjacent to paramere with Vshaped carina close to apex ( Fig. 47); paramere markedly longer, apical portion much less asymmetrical with apex minutely sinuate ( Figs. 49, 50), apex reaching distinctly closer to apex of median lobe; sensory peg setae on underside of paramere markedly more numerous, apical setae situated as in Fig. 50.

Female. Tergite 10 of genital segment of different shape, sparsely setose, with slightly differentiated apical portion, and strongly sclerotized portion reduced to very apex ( Fig. 51).

Length 14.0–18.0 mm.

Geographical distribution. Ocypus imurai is at present known only from the type locality in Wawu Shan, Ebian county , Sichuan .

Bionomics. The specimens of the original series were taken from pitfall traps set in a secondary Abies forest with Rhododendron and Sasa undergrowth.

Recognition and comments. Ocypus imurai may be easily distinguished from O. sericeomicans by the different aedoeagus, particularly by the markedly different paramere, as well as by the distinctive shape of tergite 10 of the female genital segment.
