The Nematocera are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae. Major families in the suborder include the mosquitoes, crane flies, gnats, black flies, and a group of families described as midges.
The Mycetophilidae are a family of small flies, forming the bulk of those species known as fungus gnats. About 3000 described species are placed in 150 genera, but the true number of species is undoubtedly much higher. They are generally found in the damp habitats favoured by their host fungi and sometimes form dense swarms.
The Lauxaniidae are a family of acalyptrate flies. They generally are small flies with large compound eyes that often are brightly coloured in life, sometimes with characteristic horizontal stripes, such as in Cestrotus species. Many species have variegated patterns on their wings, but in contrast they generally do not have variegated bodies, except for genera such as Cestrotus, whose camouflage mimics lichens or the texture of granitic rocks.
Xylomyidae is a family of flies known commonly as the wood soldier flies. They are xylophagous and are associated with dead or dying wood.
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.
Sciaroidea is a superfamily in the infraorder Bibionomorpha. There are about 16 families and more than 15,000 described species in Sciaroidea. Most of its constituent families are various gnats.
Bolitophila is the sole genus in the Bolitophilidae, a family of Diptera, with around 40 Palaearctic and about 20 Nearctic species, and three species from the Oriental region (Taiwan). They are small (6–9 mm.)
The Ditomyiidae are a small family of flies (Diptera).They are found worldwide, most species are found in the Australasian and Neotropical realms. There are only two genera in Europe Ditomyia Winnertz, 1846 and Symmerus Walker, 1848 Ditomyia is found in Central Europe Symmerus in Northern Europe Symmerus is endemic to the Palaearctic.
Allocotocera is a genus of flies in the family of Mycetophilidae. Two of the species are found in Europe.
The family Nothybidae contains only the genus Nothybus, a group of colorful and elongated flies. The family has been recently revised.
Boletina trivittata is a Palearctic species of 'fungus gnat' in the family Mycetophilidae. Members of this genus are found in a wider variety of habitats from wooded streams to wetlands and open moorland. Adults have been obtained in emergence traps in a range of situations including rotting wood and soil litter.
Symmerus is a genus of fungus gnats and gall midges in the family Ditomyiidae. There are about five described species in Symmerus.
Probolaeus is a genus of long-beaked fungus gnats in the family Lygistorrhinidae.
Ditomyia is a genus of fungus gnats in the family Ditomyiidae.
Rhipidita is a genus of fungus gnats in the family Ditomyiidae.
Nervijuncta is a genus of fungus gnats in the family Ditomyiidae.
Australosymmerus is a genus of fungus gnats in the family Ditomyiidae.
Rangomaramidae is a family of flies in the infraorder Bibionomorpha. The family, members of which are known as long-winged fungus gnats, was erected in 2002 by Jaschhof and Didham to include five new species of flies in the genus Rangomarama from New Zealand. The family was then expanded to include several other genera from across the world but preliminary studies show that the broad family, comprising several genera, is non-monophyletic.
Rangomarama is a genus of fungus gnats in the family Ditomyiidae.
