Achradocera is a genus of flies in the family Dolichopodidae. ^[2] It is distributed in the Nearctic and Neotropical realms as well as in Polynesia. ^[3] Several Afrotropical species were also placed in the genus, but in 2018 they were transferred to Chrysotus . ^[4] Achradocera was formerly considered a subgenus of Chrysotus , but was restored as a separate genus by Harold E. Robinson (1975). ^[3]

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. ^[3]
