Rhamphomyia helleni: Melander, 1928: 194 (catalogue). Rhamphomyia (Pararhamphomyia) fuscula helleni: Frey, 1955a: 480 (revision). Notes on synonymy. Frey (1922) described this species in his keys to Rhamphomyia, based on an unknown number of male and female syntypes (Frey 1955a). Frey (1955a) classified R. helleni as a subspecies of R. fuscula. He apparently considered R. helleni as a northern and eastern form of R. fuscula differing in shape and thickness of the phallus and slightly shorter body size and wing length.
