According to Kataev and Schmidt (2006) , Chydaeus semenowi is widely distributed over the Himalaya from Uttar Pradesh (India) to Bhutan, at elevations of 2400-3800 m. This species is recorded here from China (southern Xizang and northwestern Yunnan) for the first time ( Fig. 59 ). Habitat. Specimens were collected in roadside and road cut open areas, hidden under stones and other debris during daylight hours and active on the soil surface at night ( Figs 71 ). Remarks. Chydaeus semenowi , a member of the semenowi group ( Kataev and Schmidt 2006 ), is the most frequently encountered Himalayan species of Chydaeus . Specimens examined from southern Tibet are very similar in their morphology to other specimens from the Himalaya, but those from Yunnan are characterized by a smaller denticle at the apex of each pronotal basal angles, so they may represent a distinct geographical form.
