New data on two rare species of Fannia (Diptera, Fanniidae)

Abstract

Two new synonymies are proposed: Fannia fasciculata Loew, 1873 = F. baihualingensis Yan, Xu, Wang & Zhang, 2019, syn. nov.; Fannia xiaoi Fan, 2000 = F. fani Wang & Wu, 2017, syn. nov. F. fasciculata is supposed to be originated from S-E Palaearctic, though it was described from Europe. Specimens previously identified as F. fani are regarded as a case of intersex males of F. xiaoi. Taxonomy and distribution of both considered species are discussed and specified. F. fasciculata and F. xiaoi were newly recorded for Russia.
