Taxonomic notes. The type specimen of C. signifer corresponds with the type specimens of C. berlovi from Qinghai in all diagnostic characters including the morphology of the male genitalia ( Figs. 13–17 ). We therefore propose C. signifer as a junior subjective synonym of C. berlovi .

Distribution. Only known from high altitude areas of China (provinces of Gansu, Qinghai, Sichuan and Xizang) ( Hebauer 2002b, Hebauer & Ryndevich 2005, this paper). New record for the Gansu province.
