description: Dissomphalus carmenae Brito & Azevedo, sp. nov.
(Figs 1C, 3D)
Diagnosis. This species is easily recognized by having the harpe with apex short and twice longer than gonostipes, basivolsella without protuberance, the aedeagal dorsal valve narrow and the basal cover plate entirely narrow in V-shaped.
Description. Head. Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate short tooth; median clypeal carina low in profile, complete or nearly so, straight in profile or nearly so. Frons coriaceous, punctures small and dense. Vertex crest weakly incurved. Dorsal pronotal area with anterior margin ecarinate. Tergal process lateral, consisting of tuft with few setae, without depression. Genitalia. Harpe entirely wide, apical margin rounded, 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 anterior to apex of dorsal one, wide, abruptly narrowing apicad; inner margin slightly sinuous; outer margin incurved, parallel; aedeagal dorsal valve narrow, with pair of apical lobe; outer lobe long, wide, apical margin rounded and posterad; apex of inner median filament anterior to apex of lobe, directed posterad; basal cover plate entirely narrow, posterior margin strongly incurved medially; apodeme extending beyond genital ring.

Distribution. Brazil (Minas Gerais, Mato Grosso, Pará, Rondônia).
Etymology. This species is named after the engineer Carmen Velasco Portinho, the first woman in the country to obtain the title of urban planner.
Remarks. It is similar to D. martae sp. nov. by having the aedeagal dorsal valve narrow, basal cover plate narrow, and the basivolsella without protuberance. However, 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, whereas 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.
