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.Anaeropsis
Anaeropsis is a genus of stilt-legged fly. It is found in New Guinea.Calobatina
Calobatina is a genus of stilt-legged flies in the family Micropezidae. There are at least two described species in Calobatina.Cardiacephala
Cardiacephala is a genus of flies in the family Micropezidae.
Names brought to synonymy
Cardiacephala elegans is a synonym for Plocoscelus podagricus.Compsobata
Compsobata is a genus of stilt-legged flies in the family Micropezidae. There are at least 20 described species in Compsobata.Cypselosomatidae
The Cypselosomatidae are a family of true flies (Diptera) closely related to the Micropezidae. Eleven living genera and one fossil genus are described, 8 of which are in the subfamily Pseudopomyzinae; this group was formerly ranked as a family, but they have been treated as a subfamily of Cypselosomatidae since 2007. Some species are believed to be associated with bat guano.Diopsoidea
The Diopsoidea are a small but diverse cosmopolitan superfamily of acalyptrate muscoids, especially prevalent in the tropics. Some flux exists in the family constituency of this group (e.g., the Megamerinidae are sometimes placed here, but may also be placed in the Nerioidea), and the final classification is likely to require the use of molecular systematics.Grallipeza
Grallipeza is a genus of stilt-legged flies in the family Micropezidae. There are at least 40 described species in Grallipeza.Megamerinidae
The Megamerinidae are a family of flies (Diptera) with about 11 species in the genera Protexara Yang, Megamerina Rondani, and Texara Walker. They are marked by an elongated, basally constricted abdomen. The family is typically placed in the superfamily Diopsoidea (but may be placed in Nerioidea by some authors).Metopochetus
Metopochetus is a genus of stilt-legged flies. Crus is a subgenus. Species within Metopochetus are:
Micropeza is a genus of stilt-legged flies in the family Micropezidae.Muscomorpha
The Brachyceran infraorder Muscomorpha is a large and diverse group of flies, containing the bulk of the Brachycera, and, most of the known flies. It includes a number of the most familiar flies, such as the housefly, the fruit fly, and the blow fly. The antennae are short, usually three-segmented, with a dorsal arista. Their bodies are often highly setose, and the pattern of setae is often taxonomically important.
The larvae of muscomorphs (in the sense the name is used here; see below) have reduced head capsules, and the pupae are formed inside the exoskeleton of the last larval instar; exit from this puparium is by a circular line of weakness, and this pupal type is called "cyclorrhaphous"; this feature gives this group of flies their traditional name, Cyclorrhapha.Neriidae
The Neriidae are a family of true flies (Diptera) closely related to the Micropezidae. Some species are known as cactus flies, while others have been called banana stalk flies and the family was earlier treated as subfamily of the Micropezidae which are often called stilt-legged flies. Neriids differ from micropezids in having no significant reduction of the fore legs. Neriids breed in rotting vegetation, such as decaying tree bark or rotting fruit. About 100 species are placed in 19 genera. Neriidae are found mainly in tropical regions, but two North American genera occur, each with one species, and one species of Telostylinus occurs in temperate regions of eastern Australia.Nerius
Nerius is a genus of cactus flies in the family Neriidae.Plocoscelus
Plocoscelus is a genus of flies in the family Micropezidae. Species are found in Central and South Americas.Plocoscelus podagricus
Plocoscelus podagricus is a species of fly in the family Micropezidae. It is found in Brazil and Peru.Rainieria
Rainieria is a genus of stilt-legged flies in the family Micropezidae. There are at least 20 described species in Rainieria.Taeniaptera
Taeniaptera is a genus of stilt-legged flies in the family Micropezidae. There are at least 3 described species in Taeniaptera.Taeniapterinae
Taeniapterinae is a subfamily of flies in the family Micropezidae. There are at least 9 described species in Taeniapterinae.
