Dissomphalus purius Colombo & Azevedo , sp. nov.

( Figs 21 , 38 , 195, 196 )

Description. Male. Head and mesosoma black; metasoma dark castaneous. Mandible with two apical teeth; median clypeal lobe subtrapezoidal, median tooth triangular; frons coriaceous, weakly punctate. Mesosoma. Very coriaceous. T2 with lateral depressions, large, elliptical, shallow, bristles on edge, tubercle present, large, high density of seta on top, higth edge. Posterior hypopygeal margin weakly concave. Genitalia: paramere wide in dorsal view, rounded apex, arched, apex very narrow in dorsal view, smaller than to basiparamere; cuspis narrow; digitus sharp apex; aedeagal ventral ramus smaller than dorsal body, base very wide, laminar, very sharp apex; aedeagal dorsal body with two pairs apical lobes, outer pair with apex weakly rounded, inner pair very; basal process folded up; apodeme extending beyond genital ring. Female unknown.

Remarks. This species not have enough characteristics for be included in a species-group. This species has the genitalia similar to Dissomphalus inclinatus . However, the tergal process of D. purius sp. nov. has lateral depressions, large, elliptical, shallow, with bristles on the edge, tubercle present, large, with high density of seta on top, with higth edge, whereas D. inclinatus has tergal process with pair of large, subcircular sublateral depressions; each with tuft of dense setae, rectangular and inclined.
