Dissomphalus cornutus Evans, 1964

( Figs 165–169 )

Dissomphalus cornutus Evans, 1964: 46 , 52, 56–58 (Ƌ, holotype from Santa Catarina, BMNH, figs 25, 31, 36); Azevedo, 2003: 68; Redighieri & Azevedo, 2004: 333.

Diagnosis. Male. Dark castaneous. Mandible with four apical teeth. Clypeus with tridentate median lobe, median carina divided longitudinally, forming inner lozengy concavity, angled, high in profile. Malar space broad. Frons very convex, coriaceous, punctures inconspicuous. Vertex straight, corner broadly rounded, head developed behind eye. Gena with post-genal incomplete medially on anterior side, pair of teeth on hypostomal carina. Notaulus straight, narrow, only in anterior half mesoscutum. Parapsidal furrow complete. T2 with shallow, inconspicuous submedian depression, pair of tufts of long setae, which give risen directly from surface, without tubercle. Genitalia: paramere with basal half wide, developed in- and downward, apical half very narrow, arched inward; cuspis long; aedeagal ventral ramus as long as dorsal body, evenly wide with blunt apex; aedeagal dorsal body with pair of apical lobes, wide basally, outer surface convex, inner surface membranous and setose. Female unknown.

Variations. Some specimens have the clypeus with median carina less prominent.

Remarks. Thirty-one specimens of D. cornutus were registered from Espírito Santo ( Redighieri & Azevedo, 2004), and we add more two new ones. We suspect that there was a typo in the study, considering only three species and not 31.
