Family of flies From Wikipedia, the free encyclopedia
Remove ads
The Curtotonidae or quasimodo flies[1] are a small family of small grey to dark brown humpbacked flies (Diptera) with a worldwide distribution, but with very few species in the Nearctic, Australasian/Oceanian, and Palaearctic regions. Most members of the family are found in tropical to subtropical latitudes in Africa and the Neotropics. Many remain undescribed in collections, since little work on the family has been done since the 1930s.[2]

Classification
The family has at various times been placed in the Drosophilidae, Diastatidae, and Ephydridae. In 1934 Duda proposed the family name Curtonotidae and nowadays family rank is now widely accepted.[3]

Biology
Greathead (1958) records the immature stages as scavengers within egg pods of the desert locust, Schistocerca gregaria . Cuthbertson (1936) reared an Afrotropical species, Cyrtona albomacula Curran, from human faeces in Zimbabwe. Others have been found in the burrows of warthogs and ant bears.
