Campsicnemus is a genus of flies in family Dolichopodidae.

[4] Some species endemic to the Hawaiian islands are characterized by their lack of wings.

After the introduction of invasive ants and other alien species such as wild boar (Sus scrofa) [5] to the islands, some of these flightless species are believed extinct.

[6] The generic name is derived from the Ancient Greek καμψις ("curve") and κνημη ("tibia").

This refers to the modified mid tibia of the males, a male secondary sexual character that is very distinct in Campsicnemus.
