Dissomphalus acutipupu Colombo & Azevedo sp. nov.

( Figs 30–33 )

Description. Male. Head, mesosoma and metasoma black. Mandible with three apical teeth; median clypeal lobe tridentate, median tooth pointed; frons strongly coriaceous, punctate; eyes glabrous. Notauli complete; pronotal disc strongly coriaceous, punctate. Tergal process with circular depression, margins not angulate, dense tufts setae directed backward, tubercle absent. Posterior hypopygeal margin weakly concave. Genitalia: paramere with rounded apex, arched inward, constricted, very wide, specially basally, higher than the basiparamere, bifurcated in ventral view; basivolsella with projection, wide; digitus wide; volsella sickle-shaped; aedeagal ventral ramus longer than dorsal body, apex strongly narrow, laminar, medium rounded expansion; aedeagal dorsal body with two pairs of apical lobes, outer lobe with dorsal margin folded across its length, apical margin weakly serrated, ventral margin weakly serrated, inner projection present, inner lobe membranous; basal process absent; apodeme extending beyond genital ring. Female unknown.

Remarks. This species belongs to the punctatus species-group by having the tergal process with tufts of setae directed backward and the tubercles absent. It is similar to Dissomphalus jurupari sp. nov., by having the median clypeal lobe tridentate, the paramere very wide, especially basally, higher than the basiparamere, and the basal process absent. However, D. acutipupu sp. nov., has the mandible tridentate and the posterior hypopygeal margin weakly concave, whereas D. jurupari sp. nov. has the mandible bidentate and the posterior hypopygeal margin straight.
