Dissomphalus cuca Colombo & Azevedo sp. nov.

( Figs 34–37 )

Description. Male. Head and mesosoma black; metasoma dark castaneous. Mandible with three apical teeth; median clypeal lobe tridentate, median tooth rounded; frons strongly coriaceous, punctate; eyes glabrous. Notauli complete; pronotal disc strongly coriaceous, punctate. Tergal process with non-conspicuous depressions, dense tufts few setae weakly directed backward, tubercle absent. Posterior hypopygeal margin straight. Genitalia: paramere with rounded apex, slightly arched inward, higher than the basiparamere; aedeagal ventral ramus as long as dorsal body, apex very narrow, laminar, constricted; aedeagal dorsal body with two pairs of apical lobes, outer lobe very long, wide, curved ventrally, inner pair membranous, basal process absent; apodeme not extending beyond genital ring. Female unknown.

Remarks. This species belongs to the punctatus species-group by having the tergal process with its tufts of setae weakly directed backward and the tubercles absent. It is important to note, however, that the tergal process is not the standard found in punctatus species-group. Nevertheless, it fits into the definition of the group, even with fewer bristles. This species is not similar to any other species of its species-group, differing mainly by having the tergal process with few bristles, the aedeagal ventral ramus with the apex very narrow, and the aedeagal dorsal body with the outer lobe very long.
