Two common misidentifications are corrected: Brachyopa testecea of Stackelberg is a complex of two species, te stecea Fallén and B. obscura, n.sp. (U.S.S.R., Leningrad Obl., Yashchera); and Orthonevra intermedia of Stackelberg is O. stackelbergi n.sp. (U.S.S.R., Leningrad Obl., Yashchera). A lectotype is designated for Orthonevra intermedia (Lundbeck), and rossica Stackelberg is synonymized with that species.
