Campsicnemus is a genus of flies in family Dolichopodidae. There are more than 290 described species, made up of 34 Palearctic, 22 Nearctic, seven Afrotropic, 170 Australasian and Oceanian, and seven Indomalayan species.[1] 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) [2] to the islands, some of these flightless species are believed extinct.[3]
The generic name is derived from the Ancient Greek Greek, Ancient (to 1453);: καμψις ("curve") and Greek, Ancient (to 1453);: κνημη ("tibia"). This refers to the modified mid tibia of the males, a male secondary sexual character that is very distinct in Campsicnemus.
