Dissomphalus areius Brito & Azevedo  , sp. nov.

( Figs 19View FIGURES 13 – 24, 50View FIGURES 45 – 56, 81View FIGURES 76 – 87, 178–179View FIGURES 174 – 183)

Description. Male. Body length 1.55 mm. Color: body castaneous. Head ( Fig. 19View FIGURES 13 – 24). Mandible with two distal teeth. Median clypeal lobe subtrapezoidal, 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. 50View FIGURES 45 – 56). Tergal process with lateral, very shallow, subcircular and small depression, with small, high and laterad tubercle placed on inner area of depression, pit small, with short and sparse tuft of setae. Posterior hypopygeal margin weakly concave ( Fig. 81View FIGURES 76 – 87). Genitalia ( Figs 178–179View FIGURES 174 – 183): paramere with dorsal margin wide basally; apical margin truncate. Aedeagal ventral ramus higher than dorsal body, evenly narrow; cross section laminar; surface subhorizontal; inner margin sinuous; outer margin slightly sinuous; apex short, simple, translucent, slightly curved inward; additional inner ramus absent. Aedeagal dorsal body with two pairs of apical lobes; outer lobe short, horizontal and wide, with apical margin rounded and laterad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring.

Variations. Metasoma light castaneous, tubercle low and with dense tuft of setae, ventral projection of apical lobe of aedeagal dorsal body longer, narrower or even absent.

Remarks. This species is easily recognized by having the apical lobes of the aedeagal dorsal body with a small laterad expansion bear-ear-shaped. This species is similar to D. sartus  sp. nov. by having the paramere very excavated apically and the aedeagal dorsal body with three narrow, long filaments which connect the apical lobes of the aedeagal dorsal body to the basal portion of the aedeagal dorsal body. However, this species has the apical lobes of the aedeagal dorsal body with a small laterad projection, the aedeagal ventral ramus with the apex translucent and smooth, whereas D. sartus  sp. nov. has the apical lobes of the aedeagal dorsal body with the apex abruptly acute and the aedeagal ventral ramus with the apex not translucent and toothed.
