Cyamops alessandrae male
Cyamops alessandrae
Scientific classification
  • Periscelidinae
  • Stenomicrinae


Aulacigastrids are small black flies.The head is rounded. Postvertical bristles present and diverging. Ocellar bristles are present, there are two orbital bristles on each side of frons, the anterior orbital bristle directed forward and towards median line.There is one pair of frontal bristles, curving backward.Interfrontal bristles are absent. Vibrissae (a row of vibrissa-like bristles) are well developed.On the mesonotum there are two pairs of dorsoscentral bristles. The costa is continuous (not interrupted), the subcosta is incomplete. The posterior basal wing cell and discoidal wing cell are fused and the anal vein does not reach the margin of the wings. The wing is clear or with infuscated spots.Tibiae without dorsal preapical bristle. Genera include Cyamops ...

The Acalyptratae or Acalyptrata are a subsection of the Schizophora, which are a section of the order Diptera, the "true flies". In various contexts the Acalyptratae also are referred to informally as the acalyptrate muscoids, or acalyptrates, as opposed to the Calyptratae. All forms of the name refer to the lack of calypters in the members of this subsection of flies. An alternative name, Acalypterae is current, though in minority usage. It was first used by Justin Pierre Marie Macquart in 1835 for a section of his tribe Muscides; he used it to refer to all acalyptrates plus scathophagids and phorids, but excluding Conopidae.

The confusing forms of the names stem from their first usage; Acalyptratae and Acalyptrata actually are adjectival forms in New Latin. They were coined in the mid 19th century in contexts such as "Muscae Calyptratae and Acalyptratae" and "Diptera Acalyptrata", and the forms stuck.The Acalyptratae are a large assemblage, exhibiting very diverse habits, with one notable and perhaps surprising exception: no known acalyptrates are obligate blood-feeders (hematophagous), though blood feeding at various stages of the life history is common throughout other Dipteran sections.


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.


Asteiidae is a small but widespread family of acalyptrate flies or Diptera. About 130 species in 10 genera have been described worldwide. They are rarely collected.


Aulacigastridae is a very small family of flies known as sap flies. The family Stenomicridae used to be included within this family, but was moved by Papp in 1984. They are found in all the Ecoregions.


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


Cyamops is a genus of flies.

Cyamops halteratus

Cyamops halteratus is a species of fly in the family Periscelididae.

Cyamops nebulosus

Cyamops nebulosus is a species of fly in the family Periscelididae.


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)






The Opomyzoidea are a superfamily of flies.


Periscelis is a genus of flies in the family Periscelididae. There are about 14 described species in Periscelis.

Periscelis occidentalis

Periscelis occidentalis is a species of fly in the family Periscelididae.


Stenomicra is a genus of flies in the family Periscelididae. There are at least 20 described species in Stenomicra.

Stenomicra angustata

Stenomicra angustata is a species of fly in the family Periscelididae.


Superfamily Tabanoidea are insects in the order Diptera.


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.


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.
