Description
Dissomphalus citus Brito & Azevedo, sp. nov.
(Figs 21, 52, 83, 182–183)
Description. Male. Body length 1.55 mm. Color: body castaneous. Head (Fig. 21). Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina very high in profile, complete or nearly so, straight in profile or nearly so. Frons weakly coriaceous and punctures large. Vertex crest straight. Pronotal disc weakly coriaceous; anterior margin carinate. Metasoma (Fig. 52). Tergal process with lateral, very shallow, subcircular and small depression, with very small, low and posterad tubercle placed on center of depression, pit very small, with short and dense tuft of setae. Posterior hypopygeal margin strongly concave (Fig. 83). Genitalia (Figs 182–183): paramere with dorsal margin entirely wide; 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 with sinuous, slender ventral projection, curved outward; additional inner ramus absent; basal stub long and narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, subhorizontal and narrow, with apical margin rounded and dorsad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.
Variations. Head, mesosoma and metasoma light castaneous; anterior margin of pronotal disc coarse; tergal process without depression.
Remarks. This species is easily recognized by having the aedeagal ventral ramus with slender ventral projection and the carina of the median clypeal tooth very high in profile and the ventral margin of the paramere thick with thick setae. This species is similar to D. magnus by having the dorsal margin of the paramere almost straight with distinct thick setae apical and longer than the basiparamere. However, this species has the aedeagal ventral ramus abruptly narrow apicad with one ventral slender projection and the apical lobes of the aedeagal dorsal body subhorizontal whereas D. magnus has the aedeagal ventral ramus divided in two tubular, sinuous, projections and the apical lobes of the aedeagal dorsal body horizontal.
