Dissomphalus spissus Redighieri & Azevedo, 2006: 316, 318 (Ƌ, holotype from Espírito Santo, MZSP, figs 15, 16). Dissomphalus truncatus: Redighieri & Azevedo 2004: 330, part.

Diagnosis. Male. Black. Mandible with three apical teeth. Median clypeal lobe trapezoidal. Frons coriaceous, punctures shallow. Vertex straight. T2 with pair lateral depressions, reaching lateral margin of tergite; lateral margin setose, wide pitted tubercle with tuft of setae. Posterior hypopygeal margin straight. Genitalia: paramere wide; ventral margin concave; aedeagal ventral ramus as long as dorsal body, laminar, surface horizontal, apical half slightly sinuous, apex sharpened; aedeagal dorsal body with two pairs apical lobes; outer pair laminar, lateral part vertical, basal part horizontal covering dorsally inner pair basally; inner pair stout, membranous and setay. Female unknown.

Variations. Some specimens have mandible bidentate, less setae on the side of the depression tergal process, and paramere with straight apex.

Remarks. Sixty-nine specimens of D. spissus were registered from Espírito Santo (Redighieri & Azevedo, 2006), and we add more 62 new ones. Additionally, we reidentified one specimen previously identified as D. truncatus by Redighieri & Azevedo (2004) and one as D. setosus by Redighieri & Azevedo (2006) as D. spissus.
