Distribution. Gyrophaena (s.str.) discoidea is known from Far Eastern Russia (Maritime Province ( Fig. 295 )) and China (Shaanxi).

Remarks. Gyrophaena discoidea was originally described from Shaanxi, China. Based on the general shapes of the aedeagus, R. Pace compared it with the Nepalese G. narendra Pace, 1989 . Besides that, the shape of aedeagus of G. discoidea is also similar to the Palaearctic G. (s.str.) gentilis Erichson, 1839 , but clearly differs from it by the shape of the posterior portion of the male abdominal sternite VIII with two strong, moderately long and wide, curved apical projections on the apical margin.

Habitus as in Fig. 194 . Aedeagus as in Fig. 195 . Paramere as in Fig. 196 . Male abdominal tergite VIII as in Fig. 197 . Male abdominal sternite VIII as in Fig. 198 . Female abdominal tergite VIII as in Fig. 199 . Female abdominal sternite VIII as in Fig. 200 . Spermatheca as in Fig. 201 .

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