Description.
Male. Head and mesosoma black; metasoma dark castaneous. Mandible with three apical teeth; median clypeal lobe subtrapezoidal, median tooth triangular; frons strongly coriaceous, punctate. Disc pronotal strongly coriaceous. T2 with shallow, elliptical median depression, slightly elevated medially, pair of tufts of setae directed back and inward. Posterior hypopygeal margin straight. Genitalia: paramere wide, apical margin concave and very irregular, longer than basiparamere; digitus with large apex; aedeagal ventral ramus smaller than dorsal body, laminar, rounded apex, progressively narrowing apically; aedeagal dorsal body with two pairs apical lobes, outer pair with apex rounded in lateral view, setay, inner pair membranous; apodeme extending beyond genital ring. Female unknown.
Variations.
Paramere wider; ventral ramus with apex weakly rounded in lateral view; dorsal body with less seta.
Remarks.
This species is now included in
ulceratus
species-group by having the tergal process with median depression with pair of tufts. This species not is similar other of species-group. This species is mainly different because has the paramere wide, in dorsal view and apex of the aedeagal dorsal body setay.
This species goes to couplet
2 in
the key proposed by
Azevedo (1999a)
for
ulceratus
species-group and should be read as:
