Abstract

The Drosophila saltans group is the larger groups of Sophophora subgenus and consists of 21 criptical species. With base in morphologic characters he was subdivided in 5 subgroups: cordata, elliptica, parasaltans, saltans and sturtevanti. Evolutionary or genetics differentiation studies of the saltans group have been being based on morphologic analyses, chromossomical, biochemical, of the reproductive isolation, of the sequences comparison of structural genes and of transposons elements. The main and more complete work in the taxonomic and morphology area this group was accomplished by Magalhães (1962). The structures of terminalia masculine of this group are very complex and rich in details, getting sometimes difficult identify the species comparing the with the outlines introduced at work of Magalhães, because some terminalia of different species are very similar. Having in mind that the correct recognition of the species is essential for the accomplishment of the researches, at project present intend to realized an analysis detailed of the structures of terminalia masculine of 10 species included in the 5 subgroups of the saltans,group with the aim of contributing with a more informative photographic documentation and with morphologic details that help to identification them more easily .
