Dissomphalus ibrastus Brito & Azevedo, sp. nov. (Figs 12, 43, 74, 140–141) Description. Male. Body length 3.10 mm. Color: head and mesosoma dark castaneous; metasoma castaneous. Head (Fig. 12). Mandible with three distal teeth. Median clypeal lobe ill- defined, with one angulate very large tooth; median clypeal carina high in profile, complete or nearly so, straight in profile or nearly so. Frons weakly coriaceous and punctures small. Vertex crest weakly convex. Pronotal disc weakly coriaceous; anterior margin carinate. Metasoma (Fig. 43). Tergal process with lateral, deep, subcircular and large depression, with small, low and dorsad tubercle placed on center of depression, pit small, with short and sparse tuft of setae. Posterior hypopygeal margin weakly concave (Fig. 74). Genitalia (Figs 140–141): paramere with dorsal margin wide basally; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin slightly sinuous; apex long, simple, parallel; additional inner ramus absent; basal stub short and narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, horizontal and wide, with apical margin rounded and ventrad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring. Variation. Tergal process with very shallow depression. Remarks. This species is easily recognized by having the median clypeal tooth very long, the base of the outer margin of the apical lobes of the aedeagal dorsal body with two small rounded and dorsad projections. This species is similar to D. longiclypeus Azevedo by having the median clypeal tooth long. However, this species has the tergal process lateral, the apical lobes of the aedeagal dorsal body long and the aedeagal ventral ramus with the inner margin of the apex excavated, whereas D. longiclypeus has the tergal process median, the aedeagal dorsal body short and the aedeagal ventral ramus not excavated.
