Dissomphalus saci Colombo & Azevedo sp. nov.

( Figs 21–24 )

Description. Male. Head and mesosoma black; metasoma light castaneous. Mandible with three apical teeth; median clypeal lobe tridentate, median tooth pointed; frons strongly coriaceous; eyes glabrous. Notauli complete; pronotal disc strongly coriaceous. Metasomal tergite II with tergal process with non-conspicuous lateral depressions, tubercle present, pit on top, tuft of setae present. Posterior hypopygeal margin straight. Genitalia: paramere with serrated apex, slightly arched inward, wide, higher than the basiparamere; aedeagal ventral ramus as long as dorsal body, apex inverted, laminar, medium constriction; aedeagal dorsal body with two pairs of apical lobes, dorsal margin wide, apical and ventral margins weakly serrated, inner pair membranous, weakly setose, apex rounded in ventral view, basal process present, tooth-shaped; apodeme not extending beyond genital ring. Female unknown.

Remarks. This species belongs to conicus species-group by having metasomal tergite II with one pair of lateral depressions, with tubercle, with pit on top and tuft of setae. It is similar to D. umbilicus Azevedo by having the posterior hypopygeal margin straight and metasomal tergite II with tubercle pit-topped, tuft of setae. However, D. saci sp. nov. has the mandible tridentate, the median clypeal lobe tridentate, and the aedeagal ventral ramus as long as the dorsal body, whereas D. umbilicus has the mandible bidentate, the median clypeal lobe trapezoidal, and the aedeagal ventral ramus longer than the dorsal body.
