(Figs 123, 124, 125)
Dissomphalus concavatus Azevedo 1999a: 346 (♂, holotype from Paraná, DZUP, figs 98–101, 188, 189); 2003: 58; Redighieri & Azevedo, 2004: 329; 2006: 306.
Dissomphalus rectilineus: Redighieri & Azevedo 2004: 329, part.; 2006: 306, part.
Diagnosis. Male. Black. Mandible with four apical teeth. Median clypeal lobe subtrapezoidal. Front strongly coriaceous. Vertex straight. T2 with median elliptical depression, tuft of setae directed back and inward, somewhat large, separated another by slightly more than own diameter. Hypopygium with median stalk conical, posterior margin concave. Genitalia: paramere wide, apical margin incline, slightly convex and irregular, dorsal apical corner tooth-shaped; aedeagal ventral ramus short, wide, laminar, surface subhorizontal, convex ventrally, progressively narrowing apically, apical margin inclined, inner corner angled; aedeagal dorsal body with two pairs apical lobes, outer pair laminar, surface vertical, convex externally, wide in lateral view, apex slightly arched downward, inner pair membranous, densely setose. Female unknown.
Variations. Some specimens showed median clypeal lobe trapezoidal, tergal process with shallow or deep, large or small depressions.
Remarks. Seventy-six specimens of D. concavatus were registered from Espírito Santo (Redighieri & Azevedo, 2004; 2006), and we add more 46 new ones. Additionally, we reidentified 31 specimens previously identified as D. rectilineus by Redighieri & Azevedo (2004, 2006) as D. concavatus.
