Cyclorrhapha

Lonchoptera lutea, copyright Saxifraga.


Belongs within: Neoneura.
Contains: Syrphoidea, Schizophora, Platypezoidea.

The Cyclorrhapha are a clade of flies in which the larvae have developed the familiar 'maggot' form, with the head desclerotised and invaginated into the body. The earliest cyclorrhaphans are known from the Cretaceous (Grimaldi & Engel 2005). Living cyclorrhaphans include Lonchoptera, a cosmopolitan genus of small, slender flies with apically pointed wings. The biology of Lonchoptera is largely unknown though adults may sometimes be found in large numbers in humid habitats (Petersen 1987). Possible fossil members include Chimeromyia, a genus of slender flies known from Lebanese amber. The name of this genus refers to its members combining features of the Cyclorrhapha with those of its living sister group, the Empidoidea (Grimaldi & Cumming 1999).

Synapomorphies (from Grimaldi & Engel 2005): Face with pair or more of thick vibrissae; abdominal plaques lost in adults; embryos not developing in amnion; larvae saprophagous 'maggots' with maxilla absent, head desclerotised and invaginated; pupariation in ecdysed cuticle of last larval instar; arista with two small basal segments; proboscis retractile, withdrawn at rest into large oral cavity; female terminalia without acanthophorite spines.
