Dissomphalus geortus Brito & Azevedo sp. nov.

( Figs 28 View FIGURES 25 – 32 , 59 View FIGURES 57 – 63 , 90 View FIGURES 88 – 94 , 213–214 View FIGURES 211 – 222 )

Description. Male. Body length 1.16 mm. Color: head and metasoma castaneous; metasoma light castaneous. Head ( Fig. 28 View FIGURES 25 – 32 ). Mandible with four distal teeth. Median clypeal lobe ill-defined, with one rounded tooth; median clypeal carina high in profile, complete or nearly so, angled in profile. Frons weakly coriaceous and punctures small. Vertex crest strongly convex. Pronotal disc polished; anterior margin ecarinate. Metasoma ( Fig. 59 View FIGURES 57 – 63 ). Tergal process lateral, without depression, low and dorsad tubercle, pit small, with long and dense tuft of setae. Posterior hypopygeal margin sinuous ( Fig. 90 View FIGURES 88 – 94 ). Genitalia ( Figs 213–214 View FIGURES 211 – 222 ): paramere with dorsal margin wide basally; apical margin truncate. Aedeagal ventral ramus higher than dorsal body, wide, abruptly narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin sinuous; apex short, simple, slightly curved outward; additional inner ramus absent; basal stub absent. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, horizontal and narrow, with apical margin rounded and posterad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Remarks. This species is similar to D. krombeini by having the paramere expanded basally and the aedeagal ventral ramus abruptly narrowing apicad. However, this species has the tergal process with tubercle with tuft of setae and the apical lobes of the aedeagal dorsal body longer, whereas the D. krombeini has the apical lobe of the aedeagal dorsal body shorter and the tergal process linear with very short tuft of setae with one distincty long seta.
