Dissomphalus annae Brito & Azevedo , sp. nov.

( Figs 1A , 2G )

Diagnosis. This species is easily recognized by having the harpe twice longer than gonostipes, posterior margin of basivolsella pointed, the aedeagal dorsal lobes very wide, inner median filament anterior to the aedeagal dorsal lobes directed dorsad and the basal cover plate inverted triangular-shaped.

Description. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina low in profile, complete or nearly so, straight in profile or nearly so. Frons weakly coriaceous, punctures small and sparse. Vertex crest weakly incurved. Dorsal pronotal area with anterior margin coarse. Tergal process submedian, with tuft of setae. Posterior hypopygeal margin straight medially with rounded corners. Genitalia. Harpe wide basally, apical margin angulate, abaxial margin not projected; gonostipes shorter than harpe, ventral margin not excavated until outer margin of basivolsella; digitus short, basidorsal corner poorly projected; basivolsella without protuberance, without spines; aedeagal ventral valve with apex anterior to apex of dorsal one, wide, progressively narrowing apicad; inner margin outcurved; outer margin slightly sinuous, slightly curved laterad; aedeagal dorsal valve robust, with two pairs of apical lobe; outer lobe long, narrow, apical margin rounded, and posterad; apex of inner median filament anterior to apex of lobe, directed dorsad; basal cover plate narrow in lateral part, posterior margin straight or nearly so; apodeme extending beyond genital ring.
