Comparative remarks. Ito (2002) described C. kasaharai as a taxomomically rather isolated species from Hubei somewhat similar to C. schaubergeri Jedlička from Sichuan. Kataev et al. (2012) treated C. kasaharai together with C. shunichii Ito and C. fugongensis Kataev et Kavanaugh , both the latter from Yunnan, as belonging to the kasaharai species group. Members of this group are morphologically very similar to species of the irvinei group, but are distinguished from them in having not fused elytra, presence of a parascutellar setigerous pore, and presence of a basal parascutellar striole (the latter is rudimentary present in some specimens of the irvinei group). Conceivably the kasaharai species group should also include C. schaubergeri . This species is distinguished by the presence of additional lateral setigerous pores of pronotum. Chydaeus kasaharai is readily distinguished from C. shunichii and C. fugongensis by having tarsi pubescent dorsally and head and elytra distinctly punctate.
Distribution. Described from the series collected in Dashennongjia Mountain, western Hubei, China ( Ito 2002). Additional material suggests that this brachypterous species seems to be endemic to the eastern part of Daba Shan Mountain Range.
