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.
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.
The Diadocidiidae are a family of flies (Diptera), containing one extant genus with over 20 species and one extinct genus. Diadocidiidae are found worldwide, except in Africa and Antarctica. They are usually considered close to the Keroplatidae, Bolitophilidae, and Ditomyiidae, and used to be included in the Mycetophilidae. They are woodland flies, found in shaded places in forests or near streams. The larvae spin silken tubes under bark or in dead logs, and feed on hymenium of Polyporaceae fungi. The average body length for adults is around 2.5–5.6 mm.
Bolitophila is the sole living genus in the Bolitophilidae, a family of Diptera in the superfamily Sciaroidea, with around 40 Palaearctic and about 20 Nearctic species, and three species from the Oriental region (Taiwan). They are small (6–9 mm.)
Bolitophila cinerea is a Palearctic species of 'fungus gnat' in the family Bolitophilidae.
Diadocidia ferruginosa is a Palearctic species of fungus gnat in the family Mycetophilidae. They live as larvae in long dry silken tubes under bark or in rotten wood and probably feed on fungal mycelia or spores. Also associated with Peniophora.
Boletina gripha is a Palearctic species of 'fungus gnats' in the family Mycetophilidae. It is found in a wide variety of habitats from wooded streams to wetlands and open moorland. Reared from brown rot of spruce stump, spruce log bearing loose bark and decaying wood of pine. Larvae have been on the surface of decaying wood covered with Resinicium bicolor, from soil in pine forest and from fruiting bodies of Suillus bovinus.
Brachypeza bisignata is a Palearctic species of 'fungus gnat' in the family Mycetophilidae. Reared from puffballs (Lycoperdales).
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.
Brevicornu foliatum 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. Larvae develop in dead wood and in soil litter, feeding probably on microfungi.
Gnoristinae is a subfamily of fungus gnats in the family Mycetophilidae. There are about 6 genera and at least 4 described species in Gnoristinae.
Lygistorrhinidae is a family of long-beaked fungus gnats in the order Diptera. There are about 7 genera and at least 30 described species in Lygistorrhinidae.
Mycetophilinae is a subfamily of fungus gnats in the family Mycetophilidae. There are more than 30 genera and 2,000 described species in Mycetophilinae.
Symmerus is a genus of fungus gnats and gall midges in the family Ditomyiidae. There are about five described species in Symmerus.
Symmerus vockerothi is a species of non-brachycera in the family Ditomyiidae.
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.
