Dissomphalus azagus Brito & Azevedo  sp. nov.

( Figs 3View FIGURES 1 – 12, 34View FIGURES 33 – 44, 65View FIGURES 64 – 75, 101–102View FIGURES 95 – 106)

Description. Male. Body length 2.27 mm. Color: head and mesosoma castaneous; metasoma light castaneous. Head ( Fig. 3View FIGURES 1 – 12). Mandible with four distal teeth. Median clypeal lobe ill-defined, with one angulate tooth; median clypeal carina high in profile, complete or nearly so, angled in profile. Frons weakly coriaceous and punctures small. Vertex crest weakly concave. Pronotal disc weakly coriaceous; anterior margin ecarinate. Metasoma ( Fig. 34View FIGURES 33 – 44). Tergal process absent. Posterior hypopygeal margin sinuous ( Fig. 65View FIGURES 64 – 75). Genitalia ( Figs 101–102View FIGURES 95 – 106): paramere with dorsal margin wide basally; apical margin rounded. Aedeagal ventral ramus shorter than dorsal body, wide, abruptly narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin slightly sinuous; apex short, simple, parallel; additional inner ramus absent; basal stub short and narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, horizontal and narrow, with apical margin acute and dorsad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Remarks. This species is easily recognized by having the paramere entirely wide with the apex very excavated, the outer lobes of the aedeagal dorsal body with the distal region mesad and L-shaped, and the apex of the aedeagal ventral ramus acute. This species is similar to D. borus  sp. nov. by having the apex of paramere very excavated, the dorsal margin almost straight and the basiparamere shorter than the paramere. However, this species has the apical lobes of the aedeagal dorsal body long and the apex of the aedeagal ventral ramus abruptly acute, whereas D. borus  sp. nov. has the apical lobes of the aedeagal dorsal body very short and the aedeagal ventral ramus progressively narrowing apicad.
