Generic Combinations
- Microdon chalybeus Ferguson, 1926.
- Oligeriops chalybeus (Ferguson, 1926) [Cheng & Thompson, 2008 state: Hull in describing Oligeriops does not provide any diagnostic information, only a description. In his key to world genera of Microdontinae (Hull 1949), he uses two characters, the "greatly reduced" size of the eyes, hence, the larger gena, vertex and occiput, and the shape of the basoflagellomere. As noted by Ferguson (1926: 171) in respect to another Australian species with an unusual basoflagellomere (,em>alcicornis Ferguson, type of Cervicorniphora), "the antennae are most variable in the genus" Microdon. He later emphasized this variation by illustrating the antennae of most Australian Microdon species. From those illustrations one can see that at least the antennal structure of ,em>chalybeus is not unique, but common among Australian species]. —
