Male terminalia. This species has epandrial extensions, aedeagus shape and pregonites very similar to the D. emarginata ( Fig. 14B, D, E ). The epandrial ventral processes are short and parallel ( Fig. 14D ). Each surstylus has the smallest number of surstylar teeth, with an average of 20 chitinous teeth, irregularly arranged throughout the internal region, plus 6 thinner primary teeth arranged in a row and a tuft of surstylar bristles ( Fig. 14A, D ). The hypandrium is very similar to that of D. emarginata , however the median gonocoxites are divergent at the end ( Fig. 14C, D ). The most notable characteristics that differ in relation to D. emarginata are found in the aedeagus, due to the presence of a ventral protuberance, named aedeagal ventral crest and the central axis of the aedeagus has a long ventral protuberance ( Fig. 14B, E ). The phallapodeme is longer ( Fig. 14E ).
