| Popis: | Drosophila emarginata Sturtevant, 1942 (Fig. 13) Non-type material. Strain JD (Vera Cruz, Mexico): 10 males dissected. Male terminalia. The epandrial ventral processes are divergent (Fig. 13D). The epandrial extensions are located below the surstyli and they present flattened shape at their end (Fig. 13D). Each surstylus has 30 to 35 surstylar teeth, irregularly arranged throughout the internal region, plus 6 thinner primary teeth arranged in a row and a tuft of long surstylar bristles (Fig. 13D). The hypandrium is elongated and thin; the median gonocoxites converge at the end and have hypandrial bristles (Fig. 13A). The aedeagus appears sickle-like (Fig. 13C). The central axis of the aedeagus has a cleft on the dorsal region covered with scales (Fig.13B). The aedeagal apex has a hook shape, with a bipartite and pointed termination (Fig. 13B, C). The aedeagus presents a pair of large and long lateral postgonites (Fig. 13B, C), which are in continuity with the phallapodeme and extend along the entire length of the central axis. The pregonites are fused at the end and have no bristles (Figs. 13C).
