Subgenus Calomycomya Väisänen, 1984

The male mid-coxal spur is present only in Calomycomya and Mycomya s. str., though several species of Mycomya s. str. have lost it secondarily. The subgenus Calomycomya is also characterized by the bare abdominal tergite 8 of the male (Väisänen 1984: figs. 867, 885), while it is setose in Mycomya s. str. The tergal part of the male hypopygium has always a characteristic fork-like, bilobed median structure with a few apical setae (e.g. Väisänen 1984: fig. 871) and various thin lateral lobes (also a few longer apical and subapical setae in Nearctic M. yunga Väisänen, M tolteca Väisänen and M. amica Väisänen ). Unlike in mostly dark and dull-colored Mycomya s. str., the coloration in the subgenus Calomycomya is usually vivid yellow and dark brown, the ocellar prominence is distinctly darker than posterior parts of the head, and the abdominal tergites are yellow with posterior margins dark.

The subgenus is known previously from the Palaearctic, Nearctic and Neotropical regions (Väisänen 1984).
