Dissomphalus iozus Brito & Azevedo  , sp. nov.

( Figs 5View FIGURES 1 – 12, 36View FIGURES 33 – 44, 67View FIGURES 64 – 75, 105–106View FIGURES 95 – 106)

Description. Male. Body length 3.13 mm. Color: body castaneous. Head ( Fig. 5View FIGURES 1 – 12). Mandible with four 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 small. Vertex crest straight. Pronotal disc weakly coriaceous; anterior margin ecarinate. Metasoma ( Fig. 36View FIGURES 33 – 44). Tergal process absent. Posterior hypopygeal margin straight or nearly so ( Fig. 67View FIGURES 64 – 75). Genitalia ( Figs 105–106View FIGURES 95 – 106): paramere with dorsal margin entirely wide; apical margin rounded. Aedeagal ventral ramus shorter than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface horizontal; inner margin sinuous; outer margin slightly sinuous; apex short, simple, parallel; 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 dorsad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Remarks. This species is easily recognized by having the genitalia robust, the lobes of the aedeagal dorsal body with the apical region more expanded, rounded, laminar and the aedeagal ventral ramus very wide. This species is similar to D. abarus  sp. nov. by having the dorsal margin of the paramere rounded, the outer lobes of the aedeagal dorsal body long and the aedeagal ventral ramus wide. However, this species has the apex of the apical lobes of the aedeagal dorsal body rounded and laminar, the apex of the aedeagal ventral ramus without projections, whereas D. abarus  sp. nov. has the apex of the aedeagal ventral ramus not rounded nor laminar and the apex of the aedeagal ventral ramus with two small rounded projections.
