Dissomphalus rettenmeyeri Evans 1964: 45 , 52, 53–55, Gordh & Moczar 1990: 225.

Diagnosis. — Male. Length 2.94 mm. Mandible bidentate. Clypeus broadly projected forward, with small median tooth paralleled by small rounded expansion. Frons strongly coriaceous. Vertex straight, with rounded corners. Metasomal tergite II with pair of triangular and shallow lateral depressions, with lateral margin undefined, distant each other 3.6 X their diameters, with drop­shaped pit in the inner corner with tuft of very short hairs ( Figs. 136–137 ). Genitalia: paramere unusually very wide, apex truncate, cuspis thick and long, aedeagus with ventral ramus short than dorsal body, with an arrow apical expansion, dorsal body with two pairs of apical lobes, outer pair as an elongate dome­shaped lobe, inner pair membranous, stout and hairy.

Material examined. — HOLOTYPE: male, PANAMA, Barro Colorado Island , Canal Zone, 26.II.1955, Berlese refuse, C. W. Rettenmeyer col. ( USNM #64996 ).

Comments. — The genitalia of the holotype was extracted from the slide and transferred to microvial, and it is not in perfect condition, but it was figured by Evans in the original description.
