Dissomphalus abarus Brito & Azevedo  sp. nov.

( Figs 25View FIGURES 25 – 32, 56View FIGURES 45 – 56, 87View FIGURES 76 – 87, 207–208View FIGURES 198 – 210)

Description. Male. Body length 4.54 mm. Color: body dark castaneous. Head ( Fig 25View FIGURES 25 – 32). Mandible with three distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina high in profile, incomplete apically, straight in profile or nearly so. Frons strongly coriaceous and punctures small. Vertex crest straight. Pronotal disc coriaceous; anterior margin coarse. Metasoma ( Fig. 56View FIGURES 45 – 56). Tergal process with lateral, shallow, subcircular and large depression, without tubercle, with short and dense tuft of setae. Posterior hypopygeal margin straight or nearly so ( Fig. 87View FIGURES 76 – 87). Genitalia ( Figs 207–208View FIGURES 198 – 210): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin sinuous; apex short, translucent, with two small projections, slightly curved outward; additional inner ramus absent; basal stub absent. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, horizontal and wide, with apical margin rounded and slightly mesad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Variations. Head, metasoma and mesosoma castaneous; median clypeal lobe subtrapezoidal; pit of tergal process with few setae.

Remarks. This species is easily recognized by having the genitalia robust, the aedeagal ventral ramus very wide with the apex translucent with two small projections. This species is similar to D. iozus  sp. nov. by having the aedeagal dorsal body robust and the aedeagal ventral ramus very wide. However, this species has the paramere, basiparamere and the apex of apical lobes of the aedeagal dorsal body narrow and the apex of the aedeagal ventral ramus translucent with small projections whereas, D. iozus  sp. nov. has the paramere and the basiparamere wide, the apex of the aedeagal dorsal body wide and rounded and the apex of the aedeagal ventral ramus simple and not translucent.
