Drosophila septentriosaltans Magalhães, 1962

(Fig. 5)

Non-type material. Strains PLR (French Guiana): 15 males dissected; A (French Guiana): 20 males dissected; and SEP (French Guiana): 40 males dissected .

Male terminalia. The surstyli have fewer teeth than other species of this subgroup, with 15 to 16 surstylar teeth irregularly arranged throughout the internal region (Fig. 5A, C). The hypandrium presents enlarged and slightly convergent median gonocoxites, with a small hypandrial bristle at the ends of each side (Fig. 5A). The aedeagal apex is covered by scales (Fig. 5B–D), but the frontal region is smooth, where the phallotrema is found (opening through which sperm passes) (Fig. 5B). The aedeagal sheath as well as in the D. austrosaltans species has serrated and strongly chitinized crests, however it presents only five of these and the lateral crests are more protruding which results in a groove on the dorsal region (Fig. 5C, D). The ventral postgonites are like D. austrosaltans, but shorter (Fig. 5D). The aedeagal ventral processes are smaller than in the other species, they appear as a protuberance that iis in continuity with the pregonites, and they are located just below the ventral postgonites (Fig. 5D). The pregonites are long and curved backward, with the presence of two small bristles in each (Fig. 5D).
