Sculpture of marginal depression of S 3 in female: smooth, 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: smooth, rugulose. Sculpture of lateral S 4 in male: rugulose. Sculpture of medial S 5 in male: smooth, longitudinally strigose. Sculpture of lateral S 5 in male: longitudinally strigose, rugulose.

Diagnosis. Oreiscelio rugosus exhibits a large degree of variability in surface sculpture: the dorsal mesoscutum varies between areolate, longitudinally strigose, and mostly effaced; the dorsal frons is areolate to transversely rugose (Figs 13, 14); and the posterior vertex ranges from areolate to transversely rugose. Th is species is most similar to O. badius but has a more transverse shape of the frons in frontal view (Figs 107) and a preocellar pit (Figs 13, 14). Th e smooth area on the ventral gena anterior to the genal carina is a particularly useful character to identify this species (Fig. 104).
