Remarks.

Based on the description and figures by Matsumura (1914) and Anufriev (1987), this species can be distinguished from other species in this genus by the following characters: Pygofer has a lateral margin with a subtriangular outline; in dorsal view, asymmetrical, wider than long, with a triangular medioventral process. Anal segment in lateral view slender; in dorsal view asymmetrical, longer than broad, with convex lateral margins, rounded apically. Genital styles symmetrical, in lateral view with hook-shaped apex. Aedeagus has 3 spinose processes, in dorsal view, periandrium narrows near middle, with 2 spinose processes. A spine is implanted on the left side near the mid-length of the periandrium, which gently curves from the left side to right side, apex not reaching the right lateral margin of the periandrium. Another spine arises near the base of flagellum, not touching the shaft apically, apex curved and directed cephalad. Flagellum with a stout and long spine extending from the middle, this spine is about half as long as the longest spinose process, directed cephalad. Flagellum reaches the base of the periandrium.
