description: Dissomphalus ubracus Brito & Azevedo sp. nov.
(Figs 32, 63, 94, 221–222)
Description. Male. Body length 1.61 mm. Color: body castaneous. Head (Fig. 32). Mandible with three distal teeth. Median clypeal lobe ill-defined, with one angulate tooth; median clypeal carina high in profile, incomplete apically, 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. 63). Tergal process lateral, with deeply excaveted, subcircular and large depression covered by a membrane, without tubercle, pit absent. Posterior hypopygeal margin strongly concave (Fig. 94). Genitalia (Figs 221–222): paramere with dorsal margin wide basally; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, abruptly narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin slightly 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 short, horizontal and wide, with apical margin abruptly acute and dorsad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring.
Variations. Mesosoma light castaneous; metasoma castaneous; tergal process more laterad and longer.
Remarks. This species is easily recognized by having the median clypeal carina with angled elevation, the paramere very excavated and the tergal process with deeply excaveted, subcircular and large depression covered by a membrane. This kind tergal process has been never found in Dissomphalus and it is easily recognized in the genus. This species is similar to the D. gilvipes by having the paramere wide basally and the aedeagal ventral ramus short with acute apex. However, this species has the apical margin of the paramere crenulate, the apical lobes of the aedeagal dorsal body wide and horizontal and the tergal process with very excavated depression covered by a membrane, whereas D. gilvipes has the paramere smooth, the apical lobes of the aedeagal dorsal body vertical and narrow and the tergal process with a tuft of setae with distinct long lateral setae.
