Distribution. The eastern Palaearctic Gyrophaena (s.str.) permixta is known from Far Eastern Russia (Maritime Province ( Fig. 303 )) and China (Heilongjiang, Jilin, Sichuan, Yunnan)

Remarks. Gyrophaena permixta was originally described from Sichuan, China. Later, Pace (2010) recorded it from northern Yunnan. Gyrophaena bifurcata was originally described from Jilin and Heilongjiang. Assing (2005) noticed that this species is characterized by the morphology of the aedeagus and by the modification of the male abdominal tergite VII and VIII, but did not compare this species with other congeners. Based on the study of material from Maritime Province (see above) and original descriptions of both G. permixta and G. bifurcata , the senior author concluded that all these specimens are conspecific in external and internal morphology. Thus, G. bifurcata was synonymized with G. permixta .

Habitus as in Fig. 242 . Aedeagus as in Fig. 243 . Paramere as in Fig. 244 . Male abdominal tergite VIII as in Fig. 245 . Male abdominal sternite VIII as in Fig. 246 . Female abdominal tergite VIII as in Fig. 247 . Female abdominal sternite VIII as in Fig. 248 . Spermatheca as in Fig. 249 .

It is here recorded for the fauna of Russia for the first time.
