Mesosoma. Very coriaceous. T2 with lateral depressions, large, elliptical, reaching edge tergite, shallow, bristles on edge, tubercle present, large, high density seta on top, slightly facing edge. Posterior hypopygeal margin weakly concave. Genitalia: paramere wide in dorsal view, apex rounded, slightly arched, larger than to basiparamere; basivolsella wide projection, hemispheric-shape; cuspis wide; digitus very wide; aedeagal ventral ramus larger than dorsal body, base wide, straight, apex strongly bifurcated, rounded, 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 membranous; apodeme extending beyond genital ring. Female unknown.

Variations. Tergal process with depressions deepest; tubercle narrow with few density of seta on top; paramere with apex weakly rounded in dorsal view.

Remarks. This species not have enough characteristics for be included in a species-group. This species not is similar other of species-group. This species is mainly different because has the genitalia with basivolsella with wide hemispheric-shape projection; and aedeagal ventral ramus with apex strongly bifurcated.
