New and Little-Known Ulidiidae (Diptera, Tephritoidea) from Europe
New and Little-Known Ulidiidae (Diptera, Tephritoidea) from Europe. Kameneva E. P. — Improved keys to European species of Tetanops and Ulidia are provided. The shape of projections of the phallus glans is found to be essential to distinguish species in the genus Ulidia. Ulidia erythrophthalma (Meigen, 1826), U. albidipennis Loew, 1845, U. nigripennis Loew, 1845, U. parallela Loew, 1845 and U. atrata Loew, 1868 are shown to be separate species and redescribed with the use of genitalic characters. The following synonymy is established: Homalocephala albitarsis Zetterstedt, 1838 = Ortalis diopsides Walker, 1849, syn. n. = Ortalis costalis Walker, 1849, syn. n. Homalocephala apicalis (Wahlberg, 1838) = Psairoptera biseta Frey, 1909, syn. n. = Psairoptera similis Cresson, 1924, syn. n.; Homalocephala mamaevi Krivosheina et Krivosheina, 1995 is recorded for the first time from Europe (Austria, Sweden). Euxesta stigmatias Loew, 1873 is recorded for the first time in the Palaearctic Region based on a single unintentionally introduced specimen from Bulgaria. New finds of other ulidiid species in European countries are listed. Several species previously known only from Europe are recorded from Asia.
