Chloropidae, probably Oscinellinae.

Chloropidae, Rhodesiellinae: Rhodesiella plumiger (Meigen, 1830), female [misspelling: plumigera]. All four European species of the genus Rhodesiella Adams, 1905 are rarely collected: R. plumiger, R. fedtshenkoi Nartshuk, 1978, R. rotundata Nartshuk, 1991 and an undescribed species close to and partly mixed up with fedtshenkoi. The genus can easily be identified on the photographs: body black, bare eyes large and oval, with long axis vertical, gena (= jowl) much narrower than depth of 3rd antennal segment, orbital setae long and proclinate, outer vertical bristle (vti) longer than inner (vti), distinct vibrissa, ocellar triangle extending to tip of frons, ocellar bristles procurved and divergent, postocellar bristles upright and convergent, anepisternum (= mesopleuron) densely covered with hairs, arista haired. Different from the multitude of Oriental , Afrotropical, Australasian and the five species in Xizang (Tibet), Palaearctic China this species has a short scutellum [for which Cherian (2002) erected the synonymized genus Neorhodesiella]. The dark femora distinguish it from R. fedtshenkoi. In the two keys for European Rhodesiella (Duda in Lindner 1932-1933; Nartshuk & Andersson 2013 [as Aspistyla]) the colour of the 3rd antennal segment is not mentioned. But specimens of R. plumiger collected by me in Germany and the Mediterranean exactly agree with the two photos.
