Abstract

A review of the Palaearctic genus Psacadina Enderlein, 1939 is given. Diagnostic characters of Psacadina species offered in previous publications by Rozkosny (1987), Vala (1989) and Rivosecchi (1992) are discussed. The author came to the conclusion that using the shape of surstylus as the main diagnostic character leads to difficulties, while the form of sternite 5 makes it possible to make an unambiguous diagnosis. The diagnostic value of the wing pattern is confirmed. A new identification key for both sexes of Psacadina is proposed. Two new synonyms are proposed: Psacadina zernyi Mayer, 1953 = P. verbekei Rozkosny, 1975, syn. nov. and P. vittigera Schiner, 1864 = P. disjecta Enderlein, 1939, syn. nov. Distribution of Psacadina species in the eastern part of Palaearctic is significantly clarified.
