Abstract

The structure of the male terminalia sclerites has been studied in three economically significant species of fruit flies of the genus Ceratitis: C. capitata (Wiedemann, 1824), C. cosyra (Walker, 1849), and C. rosa Karsch, 1887. The structure of the male terminalia is generally similar in these species, with differences found in the shape of some structures of the genitalia: the left laterobasal part and the median outgrowth of the hypandrium, the phallapodeme, the apicodorsal rod of the glans, the ejaculatory apodeme, epandrium, and subepandrial sclerites. Some of these characters (the shapes of the dorsal part of the epandrium and the ejaculatory apodeme, the shape and size of the apicodorsal rod of the glans, in the lateral view) are noticeable on the preparation of the genitalia without separating the sclerites from each other, which is important to simplify the diagnostics in the practice of phytosanitary laboratories. The sclerites traditionally called medial or inner surstyli, or the medial side of surstyli, have been shown to be outgrowths of the subepandrial sclerite with prensisetae and thus not to be homologous to the surstyli.
