REMARKS. In this paper, we also consider species of the genus Megaphthalmoides Ringdahl, 1936 in the genus Megaphthalma . In our opinion, all the characters indicated by Ringdahl [1936:179] for the division of Megaphthalma and Megaphthalmoides are variable in genera Cleigastra [,Krivosheina, 2015, 2016], Gimnomera [ Ozerov, 2019a], Cordilura [ Ozerov, Krivosheina, 2020b], Microprosopa [ Ozerov, 2017], Scathophaga [ Ozerov, Krivosheina, 2021], Trichopalpus [ Ozerov, 2019c] and can not be used in the supraspecific taxonomy of the family. The name Megaphthalmoides is a new jounior synonym of Megaphthalma .

Two species have been recorded in Russia, M. pallida (Fallén, 1812) and M. unilineata (Zetterstedt, 1838) .

M. pallida was recorded in Russia from European part from forest zone by Gorodkov [1970] without indicating specific locality and from Far East [ Ozerov, 2009; Ozerov, Krivosheina, 2014b].

M. unilineata was noted from Kola Peninsula and West Siberia [ Gorodkov, 1970, 1986] without indicating specific locality and from Far East [ Ozerov, Krivosheina, 2014b].
