(Figs 1C, 5H)
Diagnosis. This species is easily recognized by having the apex of harpe short, the basivolsella without protuberance, the aedeagal dorsal valve narrow with lobes very long and expanded dorsally and basal cover plate in V-shaped.
Description. Head. Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one rounded tooth; median clypeal carina low in profile, incomplete apically. Frons coriaceous, punctures small and sparse. Vertex crest weakly incurved. Dorsal pronotal area with anterior margin ecarinate. Tergal process submedian, consisting of tuft with few setae, without depression. Posterior hypopygeal margin weakly outcurved. Genitalia. Harpe slightly wide basally, apical margin truncate, abaxial margin not projected; gonostipes shorter than harpe, ventral margin not excavated until outer margin of basivolsella; digitus short, basidorsal corner poorly projected; basivolsella without protuberance, without spines; aedeagal ventral valve with apex aligned with apex of dorsal one, evenly narrow; inner margin straight; outer margin sinuous, parallel; aedeagal dorsal valve narrow, with pair of apical lobe; aedeagal dorsal valve narrow, with two pairs of apical lobe; outer lobe very long, narrow, apical margin rounded and posterad; apex of inner median filament anterior to apex of lobe, directed posterad; basal cover plate entirely narrow, posterior margin broadly rounded; apodeme extending beyond genital ring.

Distribution. BRAZIL (Acre, Amazonas, Mato Grosso, Pará).
Etymology. This species is named after the biologist Marta Vannucci, the first woman in the Brazilian Academy of Science.
Remarks. It is similar to D. carmenae sp. nov. by having the aedeagal dorsal valve narrow, the aedeagal dorsal lobes wide, the basal cover plate narrow, and the basivolsella without protuberance. However, D. martae sp. nov. has the aedeagal dorsal lobes expanded dorsally, the apex of the harpe slender, and posterior margin of the basal cover plate broadly incurved, whereas D. carmenae sp. nov. has the aedeagal dorsal lobes not expanded dorsally, the apex of the harpe truncate, and the basal cover plate V-shaped.
