Las larvas de dipteros Cyclorrhapha no poseen cabeza distintiva, en su lugar poseen un pseudocefalo el cual contiene los organos sensoriales, faringe y aparato depredador (Tinkeu y Hance 1998).
Observations on the antennal morphology in Diptera, with particular reference to the articular surfaces between segments 2 and 3 in the Cyclorrhapha.
The phylogenetic classification of Diptera Cyclorrhapha, with special reference to the structure of the male postabdomen.
The Diptera are divided into three suborders: Nematocera (small, delicate insects with long, multisegmented antennae), Brachycera (compact, robust flies with short, stylate (pointed) antennae), and Cyclorrhapha (compact, robust flies with short, aristate (flagellum-like) antennae).
Cyclorrhapha constitute the essential of Brachycera species trapped.
The frequency of translocations in aedine chromosomal evolution appears elevated as in chironomids (aedines and chironomids belong to the suborder Orthorrhapha or lower diptera); in contrast, translocations in Drosophila (a member of the suborder Cyclorrhapha or higher diptera) have been rare (three translocations in 6400 structural changes in 300 species studied) (White 1978).
