Dissomphalus geniculatus Azevedo, 2001: 174, 185–186 (♂, holotype from Costa Rica, EMUS, figs 67–68).

Diagnosis. Mandible bidentate. Clypeus trapezoidal. Tergal process with pair of antero-lateral depressions, ovoid, deep, large with small pit covered by tuft of long seate. Hypopygium with posterior margin concave. Genitalia: paramere with oblique and concave apex; aedeagal ventral ramus as long as aedeagal dorsal body, laminar, surface subvertical, apical half convergent, apex bidentate; aedeagal dorsal body with three pairs of apical lobes; outer pair large, laminar, surface horizontal, outer margin with six teeth sharpened progressively, inner margin with projection; dorsal inner pair stout, membranose and setose; ventral inner pair small, laminar, narrowing to apex; basal process of aedeagal dorsal body with pair of lateral teeth. Apodeme extending beyond genital ring.

Remarks. This species is known to Costa Rica and Panama (Azevedo 2001) and now more specimens are added. In this series the specimens are quite similar to those previously studied, without any variation that worths to mention.
