Grass Flies (Diptera, Chloropidae) of Crimean Peninsula

Abstract

The fauna of grass flies (Diptera: Chloropidae) of the Crimean Peninsula is reviewed for the first time. The study is based on examination of the collection of the Zoological Institute, Russian Academy of Sciences (St. Petersburg), which includes the material collected in Crimea by the authors, the collections of the Zoological Museum of the M. V. Lomonosov Moscow State University and V. I. Vernadsky Crimean Federal University (Simferopol). The annotated list includes 92 species in 34 genera and three subfamilies. Most of the species (61) are recorded from Crimea for the first time. Six species, Chlorops horridus Becker, Ch. puncticornis Loew, Dicraeus (Oedesiella) beschovskii Nartshuk, Lasiosina chandleri Ismay, Meromyza meigeni Nartshuk and Oscinimorpha longirostris (Loew) are recorded for the first time from Russia and Eastern Europe. The characters for distinguishing Oscinimorpha arcuata Duda from O. longirostris (Loew), i.e., the structure of head and the male genitalia, are provided. The boreo-montane species Oscinella vastator (Curtis) and Meromyza curvinervis (Zetterstedt) are found on the Chatyrdag Mountain and Yaila (mostly forestless plateau in the Crimean Mountains). Species with southern European, Mediterranean and Macaronesian-Mediterranean ranges were recorded mostly on the South Coast of Crimea. The Crimean fauna of Chloropidae is compared with the faunas of Sardinia and Turkey.
