Skeleton and musculature of the male genitalia in the family Nothybidae (Diptera)

Аннотация

Sclerites and musculature of the male genitalia of Nothybidae (Diptera) were studied for the first time. Symmetry of the genital and pregenital sclerites, similar to that in Psilidae, was revealed. The muscles of the male genitalia of Nothybus resemble the apomorphic plan of Cyclorrhapha (Sciomyzidae, Scathophagidae and Calliphoridae) due to the splitting of the hypandrium and hypandrial muscles.
