Pelecorhynchidae is a small family of flies. All of the genera were originally placed in the family Rhagionidae, and their elevation to family rank has been controversial.[1] Other phylogenetic analyses have supported Pelecorhynchidae as a distinct clade from Rhagionidae.[2] The adults of Pelecorhynchus mostly feed on nectar of Leptospermum flowers. Larvae have been collected in the damp margins of swamp areas, where they feed on earthworms.[3]

Scientific classification


The genus Pelecorhynchus is known from Australia and Chile. The genera Glutops and Pseudoerinna are distributed in the Nearctic and eastern Palaearctic.

The Brachyceran infraorder Asilomorpha is a large and diverse group of flies, containing the bulk of the nonmuscoid Brachycera. The larvae of asilomorphs are extremely diverse in habits, as well.


Calyptratae is a subsection of Schizophora in the insect order Diptera, commonly referred to as the calyptrate muscoids (or simply calyptrates). It consists of those flies which possess a calypter that covers the halteres, among which are some of the most familiar of all flies, such as the house fly.

About 18,000 described species are in this group, or about 12% of all the flies yet described.


Carnoidea are a superfamily of Acalyptratae flies.


The Chironomoidea are a superfamily within the order Diptera, suborder Nematocera, infraorder Culicomorpha. This superfamily contains the families Chironomidae, Ceratopogonidae, Simuliidae, and Thaumaleidae. One of the more important characteristics used to define them is the form of the larval mouthparts.


The Culicoidea are a superfamily within the order Diptera. The following families are included within the Culicoidea:

Dixidae – meniscus midges

Corethrellidae – frog-biting midges

Chaoboridae – phantom midges

Culicidae – mosquitoes


The Culicomorpha are an infraorder of Nematocera, including mosquitoes, black flies, and several extant and extinct families of insects.


The Lauxanioidea are a superfamily of flies that includes the two large families, the Lauxaniidae and Chamaemyiidae, and the small family Celyphidae. Generally, they are small to medium, densely populated, coloured flies. The Chamaemyiidae and Cremifaniidae live as parasites on insects. The family Celyphidae look like beetles.

Some authors also recognize the family Cremifaniidae, but most place this in the Chamaemyiidae.


Muscoidea is a superfamily of flies in the subsection Calyptratae. Muscoidea, with approximately 7000 described species, is nearly 5% of the known species level diversity of the Diptera, the true flies. Most muscoid flies are saprophagous, coprophagous or necrophagous as larvae, but some species are parasitic, predatory, or phytophagous.


Oestroidea is a superfamily of Calyptratae including the blow flies, bot flies, flesh flies, and their relatives.The superfamily includes the families:


Mesembrinellidae (formerly included in Calliphoridae)



Rhiniidae (formerly included in Calliphoridae)






Oreoleptidae is a family of flies (insects in the order Diptera). The family was established in 2005 on the basis of the type species Oreoleptis torrenticola placed in the monotypic genus Oreoleptis. The only known species was collected from the Rocky Mountains where the larvae grow in torrential streams. Larvae have also been found in groundwater wells. The larvae are similar to those of Athericidae and Tabanidae but with long crocheted false-legs (prolegs) arising from abdominal segments 2-7. The larvae have hollow mandibular hooks.

The aberrant larvae had been collected in the past in the United States and considered as Athericids but entomologists had been unable to identify the adult stage until 2005 when adults were reared from larvae. The adults were found very similar to Pelecorhynchidae when identifying using the key in McAlpine's 1981 Manual of Nearctic Diptera but they stand apart due to the aedeagal tines and other male reproductive parts which indicate a clear similarity to the Athericidae and Tabanidae. The adults are dull grey with stylate antennae. The wing has cell r1 open.The name is said to be derived from Greek oreos (mountain) and leptos (thin, delicate). The proper word for "mountain" is oros (ὄρος) in ancient Greek.


Pelecorhynchus is a genus of flies from the family Pelecorhynchidae. The adults mostly feed on nectar of Leptospermum flowers.

Pseudoerinna is a genus of flies in the family Pelecorhynchidae. There are at least two described species in Pseudoerinna.

Pseudoerinna jonesi

Pseudoerinna jonesi is a species of fly in the family Pelecorhynchidae.


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.


Superfamily Tabanoidea are insects in the order Diptera.


The Brachyceran infraorder Tabanomorpha is a small group that consists primarily of two large families, the Tabanidae (horse and deer flies) and Rhagionidae (snipe flies), and an assortment of very small affiliated families, most of which have been (or could be, or sometimes are) included within the Rhagionidae. The Tabanomorpha is one of the two Brachyceran groups outside the Hippoboscoidea that contain blood-feeding (hematophagous) species, though they are not important disease vectors.

The larvae of tabanomorphs are primarily found in aquatic or semi-aquatic habitats, and are predatory. They often have "warts" or other body projections that may resemble the prolegs of caterpillars.


The Tephritoidea are a superfamily of flies. The following families are included:

Pallopteridae — flutter flies

Piophilidae — skippers

Platystomatidae — signal flies



Tephritidae — fruit flies

Ulidiidae (Otitidae) — picture-winged fliesThe Tachiniscinae, formerly ranked as the family Tachiniscidae, are now included in the Tephritidae.


Tipuloidea is a superfamily of flies containing the living families Cylindrotomidae, Limoniidae, Pediciidae and Tipulidae, and the extinct families Architipulidae and Eolimnobiidae.At least 15,300 species of crane flies have been described, most of them (75%) by the specialist Charles Paul Alexander.


The Tipulomorpha are an infraorder of Nematocera, containing the crane flies, a very large group, and allied families.

One recent classification based largely on fossils splits this group into a series of extinct superfamilies (below), and includes members of other infraorders, but this has not gained wide acceptance.
