The Curtotonidae or quasimodo flies 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.

Genera and Species
Distribution
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.
Fossils
Only one fossil species of Curtonotidae is known, Curtonotum gigas Théobald, from Oligocene deposits in France.
