Cyclorrhapha is an unranked taxon within the infraorder Muscomorpha. They are called "Cyclorrhapha" ('circular-seamed flies') with reference to the circular aperture through which the adult escapes the puparium.[citation needed] This is a circumscriptional name that has significant historical familiarity, but in the present classification, this name is synonymous with the more recent "Muscomorpha";[citation needed]
