Dissomphalus geniculatus Azevedo, 2001

( Figs 107–109 )

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.
