Asiorrhina is a genus of long-beaked fungus gnats in the family Lygistorrhinidae.
The Blephariceromorpha are an infraorder of nematoceran flies, including three families associated with fast-flowing, high-mountain streams, where the larvae can be found.
Orthorrhapha is a circumscriptional name which historically was used in entomology for an infraorder of Brachycera, one of the two suborders into which the order Diptera, the flies, are divided. As the group was paraphyletic, it has not been used in classifications in the last decade, and is effectively obsolete. However, many catalogs, checklists, and older works still contain the name. The taxa that used to be in the Orthorrhapha now comprise all of the infraorders in Brachycera excluding the Muscomorpha.
The Nematocera are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae. This group is paraphyletic and contains all flies but species from suborder Brachycera, which includes more commonly known species such as the housefly or the common fruit fly. The equivalent clade to Nematocera is the whole Diptera, with Brachycera as a subclade. Families in Nematocera include mosquitoes, crane flies, gnats, black flies, and multiple families commonly known as midges. The Nematocera typically have fairly long, fine, finely-jointed antennae. In many species, such as most mosquitoes, the female antennae are more or less threadlike, but the males have spectacularly plumose antennae.
The Nymphomyiidae are a family of tiny (2 mm) slender, delicate flies (Diptera). Larvae are found among aquatic mosses in small, rapid streams in northern regions of the world, including northeastern North America, Japan, the Himalayas, and eastern Russia. Around a dozen extant species are known, with two fossil species found in amber, extending back to the Mid Cretaceous. Under an alternative classification, they are considered the only living representatives of a separate, suborder called Archidiptera which includes several Triassic fossil members. The family has characteristics associated with the Nematocera as well as the Brachycera. The antennae are shortened as in the Brachycera and these flies are long, having a snout with vestigeal mouthparts, non-differentiated abdominal segments with large cerci. The wings are narrow and hair-fringed and have very weak venation. They are known to form cloud-like swarms in summer and the short-lived non-feeding adults have wings that fracture at the base shortly after mating.
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.
Mycetophilidae is 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.
Bengalia is a genus of blow flies in the family Calliphoridae with one authority considering the genus to belong to a separate family Bengaliidae. These bristly and, unlike the greens and blues of most calliphorids, dull coloured flies, are especially noted for their relationship to ants. Little is known of their biology and life-cycle, although adults of many species are kleptoparasitic on ants and will snatch food and pupae being carried by ants or feed on winged termites. The apt name “Highwayman Fly” was given by an early observer of their way of robbing ants. Very little is known about their breeding habits. The genus is found in the Afrotropical and oriental region with one species from Australia possibly a recent introduction.
Stomorhina is a genus of flies in the family Rhiniidae.
The Perissommatidae are a family of flies (Diptera) that was proposed in 1962 by Donald Colless based on the species Perissomma fusca from Australia. The family now includes five extant species within the single genus Perissomma, four from Australia and one from Chile. The Perissommatidae are unusual as they appear to have four compound eyes. They have a small slender body less than 2 mm in length. Their wings are large in comparison to their bodies and subsequently their flight is weak. Preferring high-altitude forest environments, adults only fly in the winter. The larvae live in decaying leaf litter in wet sclerophyll or cool rain forests. Some species are suspected to be associated with fungi. In the case of Perissomma macalpinei, numbers of adults have been observed congregating in clumps of foliage and rising in short, zigzag flights in the sunlight above the foliage for short periods before descending.
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).
Lygistorrhininae, commonly called long-beaked fungus gnats is a subfamily of flies in the Diptera family Keroplatidae.
Lygistorrhina is a genus of long-beaked fungus gnats in the family Lygistorrhinidae. There are at least 20 described species in Lygistorrhina.
Blagorrhina is a genus of long-beaked fungus gnats in the family Lygistorrhinidae.
Gracilorrhina is a genus of long-beaked fungus gnats in the family Lygistorrhinidae.
Labellorrhina is a genus of long-beaked fungus gnats in the family Lygistorrhinidae.
Loyugesa is a genus of long-beaked fungus gnats in the family Lygistorrhinidae.
Probolaeus is a genus of long-beaked fungus gnats in the family Lygistorrhinidae.
Polleniidae is a family of flies in the order Diptera. There are at least 6 genera and more than 190 described species placed definitively in Polleniidae, and other genera whose placement here is considered uncertain. The largest genus is Pollenia, with close to 190 species of flies commonly called "cluster flies".
