03C087F1FF91196AFF7DB58DFD83FEEB.taxon	discussion	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.	en	Ba, Yi-Bin, Ren, Guo-Dong (2013): Two new species and one new combination of Stenosini (Coleoptera: Tenebrionidae) from Xizang, China.
