Differential diagnosis
Cheilosia semifasciata is characterized by the combination of bare face, bare eye, at least base of tibiae yellow, posterior margin of scutellum with setae and ventral and dorsal pile patches on katepisternum widely separated. Easily misidentified because of inconclusive pattern on Sterna II–IV, not being uniformly shiny nor pruinose: on anterior part distinctly pruinose, on posterior part usually shiny. Males can be distinguished from similar species by the distinct pruinose spots on the abdomen (two large grey pruinose spots on terga II–IV) and the females by the scutum with erect golden pile. For identification from similar but extralimital C. fasciata Schiner & Egger, 1853, see Bot & Van de Meutter (2023).
Material examined
Not collected in 2018, but collected in 2019.
GEORGIA • 1 ♂, Samegrelo-Zemo Svaneti; 43.1166° N, 42.7276° E; 1850 m a.s.l.; 14 Jun. 2019; X. Mengual leg.; ZFMK, ZFMK-DIP-00066393 = ZFMK-TIS-8008774.
Genetics
COI sequences of C. semifasciata from Europe and Caucasus cluster together with high support (BS = 100%).
Remarks
Barkalov (1993) reported a single female of C. semifasciata collected in Lars, a small town in the Republic of North Ossetia-Alania. Thus, our record is the first for Georgia.
Distribution
Europe, Caucasus (Georgia, Russia).
