Acta Entomologica Musei Nationalis Pragae 38: 415-524, 1970
Abstract: The present paper is a revision of Palaearctic species of the genus Tachydromia
Meigen, 1803 (= Sicodus Raf., 1815, Tachista Loew, 1864) based on study of the
type material and many collections of European Museums and Institutions. At the
present time there are known on the whole 45 species of this genus in the
Palaearctic region. Some new synonymy is established: Tachysta styriaca var.
semifasciata Strobl, 1893 is synonym of T. ornatipes (Becker, 1890); Tachysta
connexa var c Strobl, 1893 is synonym of T. arrogans (Linnaeus, 1761); Tachista
barbata Oldenberg, 1920 is synonym of T. styriaca (Strobl, 1893); Sicodus
submorio Collin, 1961 is synonym of T. costalis (von Roser, 1840). A lectotype
is designated for Tachydromia denticulata (Oldenberg, 1912), T. aliterpicta
(Becker, 1889), T. ornatipes (Becker, 1890), T. styriaca (Strobl, 1893) and T.
tuberculata (Loew, 1864). Two forms, Tachysta interrupta v. obsoleta Strobl,
1910 and Tachysta arrogans v. productipes Strobl, 1910, are raised to specific
rank and five species are described here as new to science: Tachydromia parva,
sp. n., T. pseudointerrupta, sp. n., T. elbrusensis, sp. n., T. anderssoni, sp.
n. and T. caucasica, sp. n.
