Dissomphalus asfartus Brito & Azevedo , sp. nov.

( Figs 4 , 35 , 66 , 103–104 )

Description. Male. Body length 2.03 mm. Color: head and mesosoma castaneous; metasoma light castaneous. Head ( Fig. 4 ). Mandible with three distal teeth. Median clypeal lobe subtrapezoidal, with one angulate tooth; median clypeal carina low in profile, complete or nearly so, straight in profile or nearly so. Frons weakly coriaceous and punctures small. Vertex crest weakly concave. Pronotal disc weakly coriaceous; anterior margin ecarinate. Metasoma ( Fig. 35 ). Tergal process absent. Posterior hypopygeal margin sinuous ( Fig. 66 ). Genitalia ( Figs 103–104 ): 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 sinuous; apex long, crenulate, slightly curved outward; additional inner ramus absent; basal stub short and narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe short, horizontal and wide, with apical margin straight and dorsad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Description. Female. ( Fig. 223 ). Body length 1.30 mm. Body and legs light castaneous, eye black. Head 1.46 × as long as wide, side parallel slightly convex. Frons densely coriaceous, punctures large, dense and shallow. Mandible with four apical teeth, lower one larger. Clypeus with subtrapezoidal median lobe and median carina high. Eye with two facets, subcircular, distant from mandible 1.66 × its length. Vertex concave; occipital carina visible in dorsal view. Gena 0.42 × length of head. Mesosoma coriaceous. Pronotal collar 0.32 × length of pronotal disc, 1.19 × as long as wide. Mesoscutum 0.48 × length of pronotal disc, posterior margin convex. Propodeal disc long, 1.62 × as long as wide; spiracle placed at dorsolateral of propodeum, attached to lateral carina. Legs not spinose. Metasoma polished, 0.86 × as long as mesosoma. Petiole short with anterior margin in v-shaped and rugose.

Remarks. This species is easily recognized by having the eyes bulging, the dorsal margin of the paramere very expanded distally downward and the apical margin of the aedeagal dorsal body crenulate. This species is similar to D. krombeini Azevedo by having the apical portion of the dorsal margin of the paramere excavated and the aedeagal dorsal body abruptly narrowing apicad. However, this species has the dorsal margin of the paramere with the distal margin expanded downward, the apical margin of the aedeagal dorsal body crenulate and the tergal process absent, whereas D. krombeini has the dorsal margin of the paramere with the distal margin not expanded downward, the apical margin of the aedeagal dorsal body smooth and has the tergal process with the tuft of setae with one distinctly long seta.
