metasoma varying between dark castaneous with castaneous spots or fully castaneous; frontal with punctures small, shallow and irregularly sparse; vertex crest straight; lower tooth of mandible sub-angulate; last flagellomere with angulate apex; placoid sensillae elliptical; eye gibbous; scutellar groove slightly convex; ventral outer lobe of aedeagal dorsal body straight, varying between very short (apical margin of ventral pair not reaching basal region of ventral pair) and short (apical margin of ventral pair aligned with median region of ventral pair).

Remarks. Dissomphalus verus sp. nov. is similar to D. browni because of the following characteristics: hypopygium with long and narrow median stalk, lateral margins slightly convergent posterad, posterior margin with angulate corners, dorsal outer lobe of aedeagal dorsal body with laminar process, ventral outer lobe of dorsal body short and arched; aedeagal ventral ramus as long as dorsal body, apex with triangular cross-section. However, D. verus sp. nov. differs from D. browni as follows: lateral stalks of hypopygium triangular, apical region of median stalk with constriction, posterior margin slightly sinuous; base of paramere wider than basiparamere apex; base of aedeagal dorsal body wide, laminar process sickle-shaped with apical margin strongly concave; outer ventral lobe of dorsal body strongly arched with round apex.
