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.
