Drosophila saltans Sturtevant, 1916

(Fig. 2)

Non-type material. Strain S 4 (San Jose, Costa Rica): 60 males dissected .

Male terminalia. The hypandrium of this species is very similar to that of D. prosaltans, however, the median gonocoxites, where the hypandrial bristles are inserted, are more rounded, in addition to being smoother and slightly grooved (Fig. 2A, B). In the phallus, the aedeagal apex (Fig. 2A–E) is more flattened than D. prosaltans; it displays longer bristles-like structures (Fig. 2E), instead of scales ( D. prosaltans), projecting a punctiform region due to the number of long bristles. The aedeagal sheath is smooth, with a strongly serrated edge (Fig. 2C–E). The aedeagal ventral processes (Fig. 2B, C, E) are short and curved backward. The ventral postgonites are long and extend in parallel across the ventral region of the aedeagus (Fig. 2B, C, E). The pregonites are elongated and curved inward; they extend from the insertion of the phallapodeme to the middle ventral region of aedeagus and each pregonite carries two smaller bristles (Fig. 2C).
