Aedeagus (Fig. 878 and 879 in Spencer & Steyskal 1986 ): basiphallus slightly sclerotized; mesophallus elongated, wider basally; reniform sclerite present between mesophallus and distiphallus; distiphallus short, forming two lobes and with paired distal processes.

Calycomyza platyptera has already been associated to 19 genera of host-plants belonging to the Asteraceae family ( Benavent-Corai et al. 2005 ; Eiseman & Lonsdale 2018 ), forming blotches on the surface of the leaf. The yellowish fronto-orbital plate, white calypter and fringe, legs completely brown and the tubular aedeagus are helpful to distinguish C. platyptera from many others species of Calycomyza . Among species of this genus with a tubular aedeagus, especially that mining Asteraceae , C. platyptera has an aedeagus similar to C. obscura Spencer , C. promissa (Frick) , C. minor (Spencer) e C. solidaginis (Kaltenbach) , distinguished by the sclerotized extensions present apically in the distiphallus. This set of characteristics are useful to distinguish C playtera from others species of Calycomyza .
