Cyclorrhapha is an unranked taxon within the infraorder Muscomorpha. They are called "Cyclorrhapha" with reference to the circular aperture through which the adult escapes the puparium...

They are similar to most of the familiar Muscomorpha with one notable exception; they do not possess a ptilinum, and therefore lack the prominent ptilinal suture on...

, a division he based on differences in the frontal region of the head. Aschiza have no ptilinum
Ptilinum
The ptilinum is an eversible pouch on the head, above the base of the antenna in schizophoran flies . It is used to force off the end of the puparium in order for the fly to emerge, and after this inflation at emergence, the ptilinum collapses back inside the head, marked thereafter only by the...
