Medvedev, 1998: 574–575; Medvedev, 2001: 119, 216, 327; Shi & Ren, 2007: 34; Liu & Ren, 2009: 447.

Remarks. Medvedev (1998) described this species based on 2 males labeled: Holotype: male, China, Sichuan, Songpan, 1894 (M.M. Berezovskii). Paratype: male “Sze-tchuan, 26. VII. 1885, G. Patanin [G. Potanin]”. On 21 July 2009, a few specimens of this species were collected by the authors from the type locality. Although the types were unavailable in our study, we are confident in our identification, permitting us to describe the formerly unknown female of this species here.
