Dissomphalus leliae Brito & Azevedo , sp. nov.

( Figs 1C , 5A )

Diagnosis. This species is easily recognized by having the aedeagal dorsal body long, with the lateral margins slightly incurved medially, the apodeme extending far beyond the genital ring and the basal cover plate narrow and very incurved medially.

Description. Head. Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina high in profile, complete or nearly so, straight in profile or nearly so. Frons coriaceous, punctures large and sparse. Vertex crest straight or nearly so. Dorsal pronotal area with anterior margin coarse. Tergal process submedian, consisting of tuft with few setae, without depression. Posterior hypopygeal margin incurved medially. Genitalia. Harpe entirely wide, apical margin rounded, and abaxial margin not projected; gonostipes shorter than harpe, ventral margin not excavated until outer margin of basivolsella; digitus short, basidorsal corner strongly projected; basivolsella with wide, well-defined protuberance, without spines; aedeagal ventral valve with apex anterior to apex of dorsal one, wide, progressively narrowing apicad; inner margin excavated; outer margin slightly sinuous, slightly curved laterad; aedeagal dorsal valve bottle-shaped or nearly so, with two pairs of apical lobe; outer lobe 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 slightly incurved medially; apodeme extending beyond genital ring.

Distribution. Bolivia, Brazil (Amazonas, Pará), Ecuador.

Etymology. This species is named after the anthropologist Lélia Gonzalez, one of the main authors of black feminism in Brazil.

Remarks. It is similar to D. guidonae sp. nov. by having the harpe narrow and weakly incurved apically, the outer lobes long, and the apex of inner median filament almost aligned with apex of aedeagal dorsal lobes. However, D. leliae sp. nov. has the basivolsellar protuberance well-defined, the basal cover plate incurved medially, and the aedeagal dorsal outer lobes long, whereas D. guidonae sp. nov. has basivolsella without protuberance, the basal cover plate not incurved medially, and the outer lobes not too long.
