Mycomya klossi
Mycomya klossi is smaller (wing length 2.5 mm) than the other Oriental species of the subgenus, very pale, and with relatively conspicuous wing markings compared to the other Mycomya species, resembling those in the genus Neoempheria. The long, apically rounded shape of the sternal lateral appendage, with dense setosity, is diagnostic to M. klossi. It is closely related to M. paraklossi, another yellowish species, with only the posterior margins of abdominal tergites 1–5 brown and large setose sternal lateral appendages. However, M. paraklossi is bigger than M. klossi and the subapical part of its sternal lateral appendage is much wider that the basal part. Mycomya aonyx Väisänen from Myanmar is also quite similar to M. klossi, but its sternal lateral appendage is D-shaped (Väisänen 2013a: fig. 4B) and not as symmetrically rounded as in M. klossi, it lacks the conspicuous wing markings, and it has a darker coloration, with abdominal tergites 1–5 brownish to brown, sometimes with yellowish anterolateral spots.
