Drosophila nigrosaltans Magalhães, 1962

( Fig. 6 )

Non-type material. Strain NIG ( French Guiana): 54 males dissected .

Male terminalia. The median gonocoxites is slightly grooved and presents a divergent hypandrial bristle at the ends of each side ( Fig. 6A ). The aedeagal apex is elongated and curved back ( Fig. 6B–D ); it displays scales on the ventral portion and structures like long bristles along the apex ( Fig. 6E ). The dorsal region of the aedeagus presents a protuberance, named aedeagal dorsal crest ( Fig. 6D ). The aedeagal sheath is elongated, smooth and without serrated edge ( Fig. 6D ). The ventral postgonites are thinner at the end, the middle portion of this structure is slightly serrated ( Fig. 6B–D ). The aedeagal ventral processes are thin, bifurcated and they have the ends facing outwards ( Fig. 6B–D ). Each pregonite displays two small bristles ( Fig. 6B–D ).
