Dissomphalus fredi Colombo & Azevedo , sp. nov.

( Figs 3 View FIGURES 2 – 7 , 24 View FIGURES 20 – 25 , 77–80 View FIGURES 77 – 86 )

Description. Male. Head and mesosoma black; metasoma dark castaneous. Mandible with two apical teeth. Median clypeal lobe trapezoidal, median tooth triangular. Frons strongly coriaceous, punctate. Pronotal disc strongly coriaceous. T2 with lateral pair of elliptical pits, bristles dense tufts present, their inner part of covered by translucid sclerite, so that hole hemispheric. Posterior hypopygeal margin weakly concave. Genitalia: paramere with apex rounded, slightly arched inward, very wide, specially basally; basivolsella wide projection, hemisphericshape; aedeagal ventral ramus longer than dorsal body, laminar, surface vertical, apex irregularly; aedeagal dorsal body with two pairs apical lobes, outer pair wide, rounded in lateral view, dorsal margin folded across its length, apical and ventral margins serrated, inner pair membranous and setose; apodeme not extending beyond genital ring. Female unknown.

Variations. Tergal process with dense tufts or not; paramere with narrow apex.

Remarks. This species is included in hemisphaericus species-group by having the tergal process hemisphericshaped with their inner part of covered by translucid sclerite. This species not is similar other of species-group. This species is mainly different because has the tergal process with bristles dense tufts and basivolsella with wide projection.

This species goes to couplet 54 in the key proposed by Redighieri & Azevedo (2006) and should be read as:

54. Aedeagus not much wide, apex curved inward, outer dorsal body with corrugated surface and ventral margin strongly fringed, aedeagal ventral ramus narrow........................................................... D. undatus Azevedo - Aedeagus much wide or much short, apex not curved inward, outer dorsal body without corrugated surface and ventral margin weakly fringed, aedeagal ventral ramus wide.............................................................. 54a 54a. Posterior hypopygeal margin straight; paramere wider medially; aedeagal ventral ramus shorter than aedeagal dorsal body......................................................................................... D. gordus Azevedo - Posterior hypopygeal margin weakly concave; paramere very wide, specially basally; aedeagal ventral ramus larger than aedeagal dorsal body....................................................................... D. fredi sp. nov.
