Dissomphalus ardonius Brito & Azevedo  , sp. nov.

( Figs 9View FIGURES 1 – 12, 40View FIGURES 33 – 44, 71View FIGURES 64 – 75, 133–135View FIGURES 123 – 135)

Description. Male. Body length 3.22 mm. Color: body castaneous. Head ( Fig. 9View FIGURES 1 – 12). Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina high in profile, complete or nearly so, straight in profile or nearly so. Frons weakly coriaceous and punctures small. Vertex crest weakly concave. Pronotal disc coriaceous; anterior margin coarse. Metasoma ( Fig. 40View FIGURES 33 – 44). Tergal process with lateral, shallow, circular and small depression, with large, very low and dorsad tubercle placed on center of depression, pit large, with short and sparse tuft of setae. Posterior hypopygeal margin median straight with angled corners ( Fig. 71View FIGURES 64 – 75). Genitalia ( Figs 133–135View FIGURES 123 – 135): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, entirely wide, cross section laminar; surface vertical; inner margin strongly sinuous; outer margin slightly sinuous; apex long, slightly crenulate, parallel; additional inner ramus long; basal stub long and narrow. Aedeagal dorsal body with two pairs of apical lobes, outer lobe long, vertical and very narrow, with apical margin acute and ventrad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring.

Variation. Metasoma light castaneous.

Remarks. This species is easily recognized by having two spines in the ventral margin of the apical lobes of the aedeagal dorsal body with apical spine shorter than distal one, the aedeagal ventral ramus vertical and wide in the median portion with wavy apex. This species is similar to D. urazius  sp. nov. by having spine in the ventral margin of apical lobes of the aedeagal dorsal body and the aedeagal ventral ramus entirely wide with the inner margin sinuous. However, this species has the dorsal margin of the paramere sinuous, the apex of the basal bar not projected forward, and the apical margin of the aedeagal dorsal body wavy, whereas D. urazius  sp. nov. has the dorsal margin of the paramere not sinuous, the apex of the basal bar projected forward and the apical margin of the aedeagal ventral ramus not wavy.
