First data on males of the saw-fly genus Pseudarge Gussakovskij, 1935 (Hymenoptera, Argidae) from Middle Asia

Species of argid saw ies of the small genus Pseudarge Gussakovskij, 1935 were known for a long time only from females. The article provides for the rst time illustrated descriptions of males of two Middle Asian species, Pseudarge rubicunda Gussakovskij, 1935 and Ps . ushinskii Gussakovskij, 1935, and also provides characters from the description of the male Pseudarge eversmanni Gussakovskij, 1935 by V. M. Yermolenko, which was overlooked by the authors of the genus revision. Photo illustrations are given for these three species (including habitus of primary types and genital structures of both sexes), as well as an amended identi cation key. Intraspeci c variability and di erentiating characters of the species of this genus are discussed.
