Drosophila prosaltans Duda, 1927

( Fig. 1 )

Non-type material. Strains P 1 (Picinguaba, São Paulo, Brazil): 15 males dissected; P2 (Matão, São Paulo, Brazil): 20 males dissected; and P3 (Cantareira, São Paulo, Brazil): 20 males dissected .

Male terminalia. The hypandrium presents a median gonocoxite with a long hypandrial bristle at the end of each side and the lateral gonocoxites are slightly pointed at the extremities ( Fig. 1D ). In the phallus, the apex of the aedeagus is flattened, strongly sclerotized, and covered with sharp scales ( Fig. 1A–C ). The aedeagal sheath ( Fig. 1A, C, D ) is smooth with “pleats” connected to a serrated edge and it presents spicules-like structures in the dorsal region ( Fig. 1C ). The aedeagal ventral processes are long and curved back. ( Fig. 1B, D ). The ventral postgonites extend through the ventral region of the aedeagus to its apex ( Fig.1B, D ). The pregonites are short, with a bristle on each pregonite ( Fig. 1B ).
