Dissomphalus ilarius Brito & Azevedo sp. nov.

(Figs 29, 60, 91, 215–216)

Description. Male. Body length 2.18 mm. Color: head and mesosoma castaneous; metasoma light castaneous. Head (Fig. 29). Mandible with four distal teeth. Median clypeal lobe ill-defined, with one angulate very short 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 concave. Pronotal disc weakly coriaceous; anterior margin ecarinate. Metasoma (Fig. 60). Tergal process lateral, without depression, with small, very low and dorsad tubercle, pit absent, with short and sparse tuft of setae. Posterior hypopygeal margin straight or nearly so (Fig. 91). Genitalia (Figs 215–216): paramere with dorsal margin wide basally; apical margin rounded. Aedeagal ventral ramus shorter than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin sinuous; apex long, simple, parallel; additional inner ramus absent; basal stub very short and very narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe short, horizontal and wide, with apical margin abruptly acute and posterad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Variations. Head dark castaneous; median clypeal tooth inconspicuous; pit of tubercle of tergal process with short setae.

Remarks. This species is easily recognized by having the paramere very expanded basally and four narrow projections that connect the apical lobes of the aedeagal dorsal body with the median portion of the aedeagal dorsal body and the tergal process with one minute tubercle without pit with few setae. This species is similar to the D. microtuberculatus, Azevedo by having the tergal process with two minutes tubercles. However, this species has the basiparamere shorter than the paramere, the apical lobes of the aedeagal dorsal body without flagella and the apex of the aedeagal ventral ramus progressively narrowing apicad, whereas D. microtuberculatus has the basiparamere longer than the paramere, the apical lobes of the aedeagal dorsal body with flagella and the apex of the aedeagal ventral ramus abruptly acute.
