Dolichopodidae, the long-legged flies, are a large, cosmopolitan family of true flies with more than 7,000 described species in about 230 genera. The genus Dolichopus is the most speciose, with some 600 species.
Hybotidae, the typical dance flies, are a family of true flies. They belong to the superfamily Empidoidea and were formerly included in the Empididae as a subfamily.
Antyx is a genus of flies in the family Dolichopodidae from the Australasian realm. The genus was originally placed in the subfamily Sympycninae, but it was later found to be closer to the Neurigoninae and was placed as incertae sedis within the family. In the World Catalog of Dolichopodidae by Yang et al. (2006), the new subfamily Antyxinae was proposed, in which Antyx is the only genus. However, the validity of this new subfamily was later criticized by Sinclair et al. (2008). According to them, the subfamily's erection by Yang et al. (2006) was not justified by their phylogenetic analysis, and the genus would have been better placed as incertae sedis until a later phylogenetic study determines its placement.
Phacaspis is a genus of flies in the family Dolichopodidae. It is known from Southeast Asia and Papua New Guinea. Flies in the genus are small, with metallic green coloring. They are marine, and are commonly found on mudflats in front of mangroves.
Teuchophorus is a genus of flies in the family Dolichopodidae.
Kowmunginae is a subfamily of flies in the family Dolichopodidae. It was proposed in the World Catalog of Dolichopodidae by Yang et al. (2006) to include two genera previously placed as incertae sedis within the family. However, the validity of this new subfamily was later criticized by Sinclair et al. (2008). According to them, the subfamily's erection by Yang et al. (2006) was not justified by their phylogenetic analysis, and the genera included would have been better placed as incertae sedis until a later phylogenetic study determines their placement.
Parathalassiinae is a subfamily of flies in the family Dolichopodidae. It is part of an extended concept of the family, Dolichopodidae sensu lato, and forms a monophyletic group with Dolichopodidae sensu stricto. It was once placed provisionally in the subfamily Microphorinae as the tribe Parathalassiini.
Neothalassius is a genus of flies in the family Dolichopodidae from Chile. It was recorded by Brooks & Cumming (2011) from the region, but was undescribed until 2016.
Chimerothalassius is a genus of flies in the family Dolichopodidae. It contains five described species, two from New Zealand, two from New Caledonia and one from the Caribbean. It also contains three undescribed species, two from New Zealand and one from Costa Rica.
Chersodromia is a genus of flies in the family Hybotidae.
Parathalassius is a genus of flies in the family Dolichopodidae. It is found along sandy sea coasts in both the Palaearctic and Nearctic realms. The name "Parathalassius" is of Greek origin, and can be translated as "near the sea".
Amphithalassius is a genus of flies in the family Dolichopodidae. It is found along sandy sea coasts in South Africa. It contains two described species, and three undescribed species known only from females. It is closely related to Plesiothalassius.
Plesiothalassius is a genus of flies in the family Dolichopodidae. It is found along sandy sea coasts in South Africa. It contains three described species. It is closely related to Amphithalassius.
Microphorinae is a subfamily of flies in the family Dolichopodidae. It is part of an expanded concept of the family, Dolichopodidae sensu lato, though it was previously considered a family of its own.
Avenaphora is an extinct genus of flies in the family Dolichopodidae. It is known from the Cretaceous of Lebanon and France.
Microphor is a genus of flies in the family Dolichopodidae, subfamily Microphorinae.
Schistostoma is a genus of flies in the family Dolichopodidae, subfamily Microphorinae.
Microphorella is a genus of flies in the family Dolichopodidae. It is currently considered both paraphyletic and polyphyletic, and several species groups may need to be recognised as subgenera or genera.
Thalassophorus is a genus of flies belonging to the family Dolichopodidae. It is known from Japan and North America.
