Dissomphalus afestus Brito & Azevedo sp. nov.

( Figs 16 View FIGURES 13 – 24 , 47 View FIGURES 45 – 56 , 78 View FIGURES 76 – 87 , 157–158 View FIGURES 148 – 162 )

Description. Male. Body length 2.70 mm. Color: head and mesosoma dark castaneous; metasoma castaneous.

Head ( Fig. 16 View FIGURES 13 – 24 ). Mandible with three 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 weakly concave. Pronotal disc coriaceous; anterior margin carinate. Metasoma ( Fig. 47 View FIGURES 45 – 56 ). Tergal process lateral, without depression, without tubercle, with short tuft of setae. Posterior hypopygeal margin straight ( Fig. 78 View FIGURES 76 – 87 ). Genitalia ( Figs 157–158 View FIGURES 148 – 162 ): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface subhorizontal; inner margin concave; outer margin sinuous; apex long, simple, slightly curved inward; additional inner ramus absent; basal stub long and narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe horizontal and wide, with apical margin angled and laterad; inner pair stout, membranous and setose; crown-process very long. Apodeme not extending beyond genital ring.

Variations. Pronotal disc coarse; tergal process with very short tuft of setae, without depression.

Remarks. This species is easily recognized by having the genitalia wide, the apical lobes of the aedeagal dorsal body very long and the inner lobe of the aedeagal dorsal body very big, extending through the outer lobes of the aedeagal dorsal body. This species is similar to D. culteratus by having apical lobes of aedeagal dorsal body long with apex laterad and paramere longer than basiparamere. However, this species has the aedeagal ventral ramus with inner margin smooth, basal half wide and apical half narrow with apex mesad, whereas D. culteratus has the aedeagal ventral ramus narrowing at apex, inner margin microserrated and apex parallel.
