Cyclorrhapha
Template:Short description Template:Automatic taxobox Cyclorrhapha is an unranked taxon within the infraorder Muscomorpha. They are called "Cyclorrhapha" ('circular-seamed flies')<ref>Template:Cite book</ref> with reference to the circular aperture through which the adult escapes the puparium.<ref>Template:Cite book</ref> This is a circumscriptional name that has significant historical familiarity, but in the present classification, this name is synonymous with the more recent "Muscomorpha".<ref>Template:Cite journal</ref>
Cyclorrhapha underwent major adaptive radiation that led to the creation of over 72 000 species. These species share multiple attributes such as the 360-degree rotation of the male terminalia.<ref>Template:Cite journal</ref>
Cyclorrhapha exhibits significant morphological and molecular diversity, including notable changes in anterior egg development, as exemplified by the role of the exuperantia (exu) gene in Anastrepha fraterculus, a species of great agricultural importance.<ref>Oliveira, J.
