Tetrachaetus
Tetrachaetus is a genus of flies in the family Dolichopodidae, found in New Zealand. The genus was originally named by Octave Parent in 1933. However, as the genus was not designated a type species, this name was unavailable until 1989, when Daniel J. Bickel and C. E. Dyte designated Tetrachaetus bipunctatus as the type species.
