Distribution
According to Kataev and Schmidt (2006)[1], 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[1]), 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.
