Achradocera is a genus of flies in the family Dolichopodidae. It is distributed in the Nearctic and Neotropical realms as well as in Polynesia. Several Afrotropical species were also placed in the genus, but in 2018 they were transferred to Chrysotus. Achradocera was formerly considered a subgenus of Chrysotus, but was restored as a separate genus by Harold E. Robinson (1975).
Adult males of Achradocera can be recognised by several secondary sex characteristics: their antennae have the first flagellomere elongated and swollen at the base with a narrow tip, and they have rows of thickened setae underneath the eyes.
