Drosophila lusaltans Magalhães, 1962

( Fig. 3 )

Non-type material. Strain B 44 ( Petionville , Haiti): 20 males dissected .

Male terminalia. The hypandrium presents rounded and convergent median gonocoxites, with a divergent median hypandrial bristle at the end of each side ( Fig. 3A, D ). The aedeagal apex ( Fig. 3A–D ) is very similar to that of D. saltans , it also has bristles; however, this species displays an apical groove that isolates two lateral protuberances on the aedeagal apex ( Fig. 3B ). The aedeagal sheath is smooth, with a serrated edge and it presents a tuft of bristles in the dorsal region ( Fig. 3B, C ). The aedeagal ventral processes, ventral postgonites and pregonites are very similar to D. saltans ( Fig. 3B, C ).
