The Nematoceran family Axymyiidae is the sole member of the infraorder Axymyiomorpha, though it is often included within the infraorder Bibionomorpha in older classifications. It is known from only nine species in four genera, plus eight fossil species.
The Curtotonidae or quasimodo flies are a small family of small grey to dark brown humpbacked flies (Diptera) with a worldwide distribution, but with very few species in the Nearctic, Australasian/Oceanian, and Palaearctic regions. Most members of the family are found in tropical to subtropical latitudes in Africa and the Neotropics. Many remain undescribed in collections, since little work on the family has been done since the 1930s.
Rhagionidae or snipe flies are a small family of flies. They get their name from the similarity of their often prominent proboscis that looks like the beak of a snipe.
Clusiidae or "druid flies" is a family of small, thin, yellow to black acalyptrate flies with a characteristic antenna and with the wing usually partially infuscated. They have a cylindrical body. The head is round, the vertical plate reaches the anterior margin of the frons and the vibrissae on the head are large. The costa is interrupted near subcosta and the latter developed throughout length. Larvae are found in the bark of trees, the flies on trunks. The larvae are notable for their ability to jump. Males of many species in the subfamily Clusiodinae have been observed while engaged in lekking behaviour. There are hundreds of species in 14 genera found in all the Ecoregions, although most species occur in tropical regions. The type genus is Clusia Haliday, 1838.
Hover flies of the genus Microdon are unusual among the Diptera. Like other members of the subfamily, they are myrmecophiles, meaning they inhabit the nests of ants.
Superfamily Tabanoidea are insects in the order Diptera.
Tephritis is a genus of flies. It contains around 170 described species, making it the sixth largest genus in the family Tephritidae. Many more undescribed species are known from specimen collections. Tephritis occur throughout much of the world, but most are Palearctic. They can be found in a wide range of climate types, from hot semidesert to tundra. Most species inhabit the inflorescences of plants from several tribes in the family Asteraceae, and a few species cause galls to form.
Nepalomyia is a genus of flies in the family Dolichopodidae.
Cornelius Becker Philip (1900–1987) was an American entomologist, noted for assigning comedic names to species he described.
Tabaninae is a subfamily in the family Tabanidae commonly known as horse flies. There are more than 3000 described species in Tabaninae.
Lygistorrhininae, commonly called long-beaked fungus gnats is a subfamily of flies in the Diptera family Keroplatidae. The groups was long treated as a separate family, but molecular phylogenetic analysis has shown it to belong to Keroplatidae. There are about 7 genera and at least 30 described species in Lygistorrhininae.
Limnellia is a genus of shore flies in the family Ephydridae.
Bezzia is a genus of biting midges in the family Ceratopogonidae. There are more than 310 described species in Bezzia.
Lasia is a genus of small-headed flies in the family Acroceridae. There are about 19 described species in Lasia, which are distributed in the New World.
Dolichopus sincerus is a species of long-legged fly in the family Dolichopodidae.
Wohlfahrtia is a genus of flesh flies in the family Sarcophagidae. There are at least 20 described species in Wohlfahrtia.
Diogmites texanus is a species of robber flies in the family Asilidae.
Stilobezzia is a genus of predaceous midges in the family Ceratopogonidae. There are more than 330 described species in Stilobezzia.
Alluaudomyia is a genus of predaceous midges in the family Ceratopogonidae. There are more than 180 described species in Alluaudomyia.
Heteromyia is a genus of biting midges in the family Ceratopogonidae. There are about 17 described species in Heteromyia.
