Sculpture of marginal depression of S 3 in female: rugulose. Sculpture of marginal depression of S 4 in female: rugulose. Sculpture of marginal depression of S 5 in female: rugulose. Apical spine on S 6 in female: extending beyond apex of T6 and visible in dorsal view. Sculpture of medial S 2 in male: punctate reticulate. Sculpture of medial S 3 in male: smooth. Sculpture of lateral S 3 in male: longitudinally strigose. Sculpture of lateral S 4 in male: rugulose. Sculpture of medial S 5 in male: smooth. Sculpture of lateral S 5 in male: longitudinally strigose.

Diagnosis. Oreiscelio badius is similar to O. rugosus , O. turneri , O. zulu and O. coracinus . Th e concave carina that delimits the subapical portion of T6 ( Fig. 42 ) serves well to identify this species. It may be reliably separated from O. rugosus by the coarse sculpture of the gena (Fig. 1), from O. turneri by the subequal size of the mandibular teeth, and from O. coracinus by the lack of an anterior pronotal pit (Fig. 8) and very faint or absent divergent carinae on the frons above the interantennal process ( Fig. 41 ). Oreiscelio badius can be separated from O. zulu by the presence of a dorsal flange on the interantennal process (Fig. 131, 132) in the latter.

Etymology. The epithet badius , meaning “brown”, refers to the color of this species.
