( Figs 5View FIGURES 2 – 7, 26View FIGURES 26 – 31, 107, 108View FIGURES 105 – 110)

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. Disc pronotal coriaceous. T2 with lateral pair of elliptical and inclined depression, linear and elliptical tufts of setae present. Posterior hypopygeal margin weakly convex. Genitalia: paramere with apex rounded, constricted, arched inward, wide, longer than basiparamere; digitus with large basal projection, serrate; aedeagal ventral ramus smaller than dorsal body, laminar, narrow, rounded apex, tapering from base to apex, base with process, inner margin waved; dorsal body with two pairs apical lobes, outer pair laminar, surface vertical, apex rounded in lateral view, serrate, inner pair membranous, basal process bifurcated, serrate; apodeme extending beyond genital ring. Female unknown.

Remarks. This species is now included in rufipalpis  species-group by having the tergal process with pair of elliptical and inclined depression with linear and elliptical tufts of setae. This species has the genitalia similar to those of D. inclinatus  . However, this species has the aedeagal dorsal body serrate, ventral ramus is not bidentate and digitus is serrated, whereas D. inclinatus  has the aedeagal dorsal body not serrate, ventral ramus is bidentate and digitus is not serrated.

This species goes to couplet 45 in the key proposed by Redighieri & Azevedo (2006) and should be read as:

45. Base aedeagal ventral ramus with process................................................................ 45a - Base aedeagal ventral ramus without process............................................................... 46 45a. Base aedeagal ventral ramus with bifurcated process.............................. D. inclinatus Redighieri & Azevedo  - Base aedeagal ventral ramus with process, but not bifurcated................................... .. D. guarani  sp. nov.
