superfamily SUPERFAMILY is a database and search platform of structural and functional annotation for all proteins and genomes. It classifies amino acid sequences into known structural domains, especially into SCOP superfamilies. Domains are functional, str ...

Acalyptratae 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 ...

flies Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced ...

Description

In general, carnoids are small flies no more than a few millimetres long. Carnoidea is a poorly defined superfamily. In 1989, ten

were described for the group, but most of these have later been challenged. As of 2006, the following synapopmorphies were described: uppermost fronto-orbital bristle(s) of the head is exclinate; phallus of the male is flexible, unsclerotized, simple and elongate; and phallus is microtrichose.

Milichiidae are also scavengers and most occur in a range of habitats, though some are restricted to ant nests, bee nests or bat dung in caves. Chloropidae are more varied in their larval ecology, including scavengers,

Phylogeny

Australimyzidae and Inbiomyiidae are
