The Bibionomorpha are an infraorder of the suborder Nematocera. One of its constituent families, the Anisopodidae, is the presumed sister taxon to the entire suborder Brachycera. Several of the remaining families in the infraorder are former subfamilies of the Mycetophilidae, which has been recently subdivided. The family Axymyiidae has recently been removed from the Bibionomorpha to its own infraorder Axymyiomorpha.
Camillo Rondani was an Italian entomologist noted for his studies of Diptera.
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.
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 Cecidomyiinae, commonly known as gall midges or gall gnats, is the largest subfamily in Cecidomyiidae with over 600 genera and more than 5000 described species. This subfamily is best known for its members that induce galls on plants, but there are also many species that are fungivores, parasitoids, or predators as maggots.
The Lasiopteridi is a supertribe of flies from the family Cecidomyiidae. They are often called gall midges or gall gnats.
Contarinia is a genus of midges, small flies in the family Cecidomyiidae. There are over 300 described species in the genus.
Exoprosopini is a tribe of bee flies in the family Bombyliidae. There are more than 20 genera and 760 described species in Exoprosopini.
Micromyinae is a subfamily of wood midges, insects in the family Cecidomyiidae. Its members were formerly included in subfamily Lestremiinae. There are at least 55 genera and more than 650 described species in Micromyinae. All species in this subfamily are mycophageous.
Mycophila is a genus of wood midges, insects in the family Cecidomyiidae. There are seven described species in Mycophila. The genus was established by Ephraim Porter Felt in 1911.
Porricondylinae is a subfamily of gall midges and wood midges in the family Cecidomyiidae.
Sitodiplosis is a genus of flies belonging to the family Cecidomyiidae.
Allarete is a genus of midges in the family Cecidomyiidae. There are twelve described species in this genus. It is known from the holarctic, afrotropical, and oriental regions. The genus was first described by Arthur Earl Pritchard in 1951.
Anarete is a genus of midges in the family Cecidomyiidae. There are 38 described species. The genus was established by Irish entomologist Alexander Henry Haliday in 1833 and has a cosmopolitan distribution.
Conarete is a genus of midges in the family Cecidomyiidae. There are 13 described species in this genus. It was established by Arthur Earl Pritchard in 1951.
Lestremia is a genus of midges in the family Cecidomyiidae. There are 18 described species in this genus. It was established by French entomologist Pierre-Justin-Marie Macquart in 1826.
Wasmanniella is a genus of midges in the family Cecidomyiidae. The three described species are known from the holarctic and oriental regions. The genus was established by French entomologist Jean-Jacques Kieffer in 1898.
Neurolyga is a genus of wood midges, insects in the family Cecidomyiidae. The 28 described species occur in the holarctic region. The genus was established by Italian entomologist Camillo Rondani in 1840.
Polyardis is a genus of midges in the family Cecidomyiidae. The ten described species are found in the Holarctic and Australasian realms. The genus was first described by entomologist Arthur Earl Pritchard in 1947.
