Dissomphalus torem Colombo & Azevedo   sp. nov.

( Figs 60–65 View FIGURES 56–70 )

Description. Male. Head and mesosoma black; metasoma dark castaneous. Mandible with three apical teeth; median clypeal lobe trilobate, median tooth pointed; frons coriaceous, punctate; eyes glabrous. Notauli complete; pronotal disc coriaceous, punctate. Metasomal tergite II with tergal process with one pair of conspicuous median depressions, transversally elliptical, tubercle present, directed each other. Posterior hypopygeal margin straight. Genitalia: paramere with weakly rounded apex, shorter than the basiparamere, slightly arched inward; aedeagal ventral ramus shorter than dorsal body, apex rounded, laminar, basal projection present; aedeagal dorsal body with two pair of apical lobes, outer lobe very wide, curved ventrally, bifurcated apex forming two teeth, inner pair with apex setose and half basal membranous, basal process absent; apodeme not extending beyond genital ring. Female unknown.

Remarks. This species belongs to the vallensis species-group by having the tergal process with one pair of conspicuous median depressions, transversally elliptical, tubercle present, directed toward each other. It is similar to Dissomphalus extrarramis Azevedo   by having the mandible with three apical teeth, the aedeagal dorsal body with two pairs of apical lobes, outer lobe arched downward apically with two sharpened teeth at the edge, and paramere smaller than basiparamere. However, D. torem   sp. nov. has the aedeagal ventral ramus with basal projection present, inner lobe with apex very setose, and two teeth in the basal part of the outer lobe, whereas D. extrarramis   , has the aedeagal ventral ramus without a basal projection present, inner lobe without apex densely setose, and never with two teeth in the basal part of the outer lobe.
