Carnoidea Conopoidea Diopsoidea Ephydroidea Lauxanioidea Lonchaeoidea Nerioidea Opomyzoidea Sciomyzoidea Sphaeroceroidea Tephritoidea The Acalyptratae or Acalyptrata are a subsection of the Schizophora, which are a section of the order Diptera, the "true flies".

All forms of the name refer to the lack of calypters in the members of this subsection of flies.

It was first used by Pierre-Justin-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.

[1] 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 classification of the Acalyptratae has varied over time, and the below list is likely to change in future.
