Colombo, Wesley D. & Azevedo, Celso O., 2016, Review of Dissomphalus Ashmead, 1893 (Hymenoptera, Bethylidae) from Espíri- to Santo, Brazil, with description of twenty-one new species, Zootaxa 4143 (1), pp. 1-84 : 52-53

Dissomphalus taiabocu Colombo & Azevedo , sp. nov.

( Figs 22 , 39 , 197, 198 )

Description. Male. Head and mesosoma black; metasoma dark castaneous. Mandible with two apical teeth; clypeus broad, median tooth rounded; frons coriaceous, punctate. Mesosoma. Very coriaceous. T2 without depressions, tubercle absent, very small lateral pits, few bristles. Posterior hypopygeal margin straight. Genitalia: paramere wide in dorsal view, apex rounded, slightly arched, larger than to basiparamere; cuspis wide; digitus wide, rounded apex; aedeagal ventral ramus smaller than dorsal body, base wide, rounded, narrow apex, rounded, laminar; aedeagal dorsal body with two pairs apical lobes, outer pair with narrow apex, inner pair very serrated; basal process with two projections; basal bar very wide; apodeme extending beyond genital ring. Female unknown.

Remarks. This species not have enough characteristics for be included in a species-group. This species is mainly different because has the genitalia with paramere short and aedeagal ventral ramus with median part with projection. This species has the genitalia similar to Dissomphalus caparao sp. nov. However, the paramere of D. taiabocu sp. nov. is wide in dorsal view, the aedeagal dorsal body with basal process with two projections and apodeme extending beyond genital ring, whereas D. caparao sp. nov. the paramere is small, in dorsal view; the aedeagal dorsal body without basal process with two projections and apodeme not extending beyond genital ring.
