Pseudethas ( Pseudethas) convexigenus ( Ren & Shi, 2006) comb. nov.

Indochillus convexigena Ren & Shi, 2006: 182 , Figs 13 –22, 24.

Type material examined. HOLOTYPE: J, ‘ CHINA: XIZANG: Lhasa , 23.viii.2003, Ren Guodong leg.’ ( MHBU) . PARATYPES: 5 JJ 4 ♀♀, same label data as holotype ( MHBU).

Discussion. The status of Indochillus convexigena Ren & Shi, 2006 was questioned by FOUQUÉ (2008). The species should be transferred to the subgenus Pseudethas of the genus Pseudethas based on the following characters: elytral surface flattened, lateral margins of elytra parallelsided; base of elytra wider than pronotal base; epipleura of elytra with one row of punctures; males possessing small tooth on inner side of meso- and metatibiae; tempora convex laterally behind eyes; shallow median depression present on disc of pronotum. The species is similar to Pseudethas ( Pseudethas) ladakhensis Kaszab, 1978 ( KASZAB et al. 1978), but differs from the latter as follows: punctures of pronotum sparser; humeral angles of elytra rounded and not expending outwards; and antennae being more slender.

Distribution. China: Xizang (Lhasa).
