( Figs 26 View FIGURES 25 – 32 , 57 View FIGURES 57 – 63 , 88 View FIGURES 88 – 94 , 209–210 View FIGURES 198 – 210 )

Description. Male. Body length 3.13 mm. Color: head dark castaneous; mesosoma and metasoma castaneous. Head ( Fig. 26 View FIGURES 25 – 32 ). Mandible with two distal teeth. Median clypeal lobe ill-defined, with one angulate tooth; median clypeal carina low in profile, incomplete apically, straight in profile or nearly so. Frons weakly coriaceous and punctures large. Vertex crest straight. Pronotal disc weakly coriaceous; anterior margin ecarinate. Metasoma ( Fig. 57 View FIGURES 57 – 63 ). Tergal proces with lateral, shallow, subcircular and small depression, without tubercle, with very short tuft of setae. Posterior hypopygeal margin straight or nearly so ( Fig. 88 View FIGURES 88 – 94 ). Genitalia ( Figs 209–210 View FIGURES 198 – 210 ): paramere with dorsal margin entirely wide; apical margin rounded. Aedeagal ventral ramus shorter than dorsal body, evenly narrow; cross section laminar; surface subvertical; inner margin concave; outer margin sinuous; apex short, simple, parallel; additional inner ramus absent; basal stub short and very narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, horizontal and narrow, with apical margin abruptly acute and ventrad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Variations. Mesosoma dark castaneous; median clypeal tooth shorter; depression of tergal process very shallow.

Remarks. This species is easily recognized by having the very long basiparamere about 2 × the size of the paramere. This characteristic does not have in other species in Dissomphalus . The paramere is wide and short, the apex of the apical lobe of the aedeagal dorsal body is articulated and the eyes are bulging.
