Remarks. This species was first recorded in Russia (Mamaev 1976) and is newly recorded from China (Zhejiang, Sichuan). It has long setae of subequal length on the flagellomeres. The ventral mesial margin of the gonocoxa has two groups of weak setae. It can be distinguished by a gonostylus with two subapical megasetae. The four specimens examined do not show distinct intraspecies variation, but the materials from Zhejiang have stronger megasetae and a more sclerotized body.
