New records of Dolichopodidae (Diptera) from the North-Western Caucasus and adjacent territories and a new synonym

During the recent years, several surveys were conducted by the Kuban State University, All-Russian Institute of Plant Protection, Institute of Cytology and Genetics SB RAS (Novosibirsk), and Zoological Museum of Moscow State University in the North-Western Caucasus and on the adjacent territories, mainly in the Russian Republic of Adygea and Krasnodar Krai. In all, 102 Dolichopodidae species were collected and identified, including Dolichopus calinotus Loew, 1871, Lamprochromus kowarzi Negrobov et Tshalaja, 1988, Medetera parenti Stackelberg, 1925, Nematoproctus distendens (Meigen, 1824), Neurigona pallida (Fallén, 1823), Poecilobothrus annulitarsis Kazerani, Pollet, Khaghaninia, 2017, Sciapus albifrons (Meigen, 1830), Sybistroma discipes (Germar, 1821), and Thrypticus bellus Loew, 1869 new for the Krasnodar Krai; Dolichopus salictorum Loew, 1871 and Medetera petrophila Kowarz, 1877 new for Adygea; and Rhaphium antennatum (Carlier, 1835) new for Rostov Oblast. Argyra atriceps Loew, 1857, Dolichopus strigipes Verrall, 1875, Gymnopternus silvestris (Pollet, 1991), Medetera lamprostomoides (?) Negrobov, 1972, Nematoproctus praesectus Loew, 1869, and Rhaphium nasutum (Fallén, 1823) are found in the Caucasus and Krasnodar Krai for the first time, while Poecilobothrus basilicus (Loew, 1869) and Medetera media Parent, 1925 are the first reports for Russia. The former Mongolian endemic Dolichopus brunneilineatus Negrobov, 1976 was unexpectedly revealed in the Krasnodar Krai near Novorossiysk. Campsicnemus armeniacus Negrobov et al., 2017 was placed in synonymy with Campsicnemus varipes Loew, 1859. Campsicnemus simplicissimus sensu Parent (1938) was found to be different from C. simplicissimus (Strobl, 1906). Most of the collected species are widespread across southern band of the Palaearctic Region.
