Distribution. China: Gansu ( Egorov, 1989).

Remarks. This species was described from Amdos highland, Gansu [including Gannan and parts of Tianzhu] with three specimens (2♂♂, 1♀), posterior angles of pronotum rectangular and sharp, median depression on dorsal surface of parameres extended to base in the original description. In this study, eight specimens were examined and their posterior angles rectangular but not sharp ( Fig. 2 : A), median depression also not extended to base ( Figs. 2 : I, 7). According to the locality, body size and other diagnostic characters of these specimens are almost same as P. amdoensis , we regarded them as variability of this species.
