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 : 45

Dissomphalus secretus Colombo & Azevedo , sp. nov.

( Figs 17 , 34 , 163, 164 )

T2 without depressions, well-defined side pits, circular-shaped, higher edges, tubercle below surface of tergite, many setae at the apex; Posterior hypopygeal margin straight. Genitalia: paramere short in dorsal view, apex serrate and very setay in ventral view, smaller than to basiparamere; aedeagal ventral ramus smaller than dorsal body, base wide, apex pointed, median part with projection, laminar; aedeagal dorsal body with two pairs apical lobes, outer pair with apex weakly rounded, inner pair very membranous; basal process ill defined; basal bar wide; apodeme extending beyond genital ring.

Female unknown.

Variations. Paramere with base longer in dorsal view; dorsal body with apex more rounded.

Remarks. This species is allocated in secretus species-group by having the tergal process with lateral depressions or not, with well-defined side pits, circular-shaped, higher edges, with a tubercle below the surface of tergite, many setae at the apex, with bristles on the edge of the depressions or not. This species not is similar other of species-group. This species is mainly different because has the genitalia with paramere short and aedeagal ventral ramus with median part with projection.
