Anterior pronotal pit: large. Pronotal cervical sulcus: well defined by contiguous punctures. Mesepimeral sulcus: indicated by dorsoventral line of foveae. Sculpture of femoral depression in female: anterior half smooth, posterior half finely foveate. Sculpture of femoral depression in male: finely foveate throughout, with weak transverse striae throughout. Mesopleural carina: indicated by one or two rows of punctures. Sculpture of ventral mesepisternum: foveate. Pilosity of metapleural triangle in female: glabrous or with at most 3 small setae. Pilosity of metapleural triangle in male: absent. Sculpture of ventral area of metapleuron: foveate reticulate, with slightly appressed ridges.

Metasoma: Submarginal ridge on T1: absent. Sublateral tergal carina on T2: absent. Sculpture of T2–T3: reticulate rugose. Sculpture of T4: reticulate rugose. Sculpure of T5: reticulate rugose. Shape of subapical T 6 in female in dorsal view: short, width along anterior margin at least three times the length. Apex of T 7 in male: slightly convex. Longitudinal medial keel on S1: present. Sculpture of medial S 2 in female: punctate reticulate. Sculpture of medial S 3 in female: effaced to smooth. Sculpture of medial S 4 in female: effaced to smooth. Sculpture of medial S 5 in female: effaced to smooth. Sculpture of lateral S 3 in female: foveolate. Sculpture of lateral S 4 in female: foveolate. Sculpture of lateral S 5 in female: foveate. Sculpture of marginal depression of S 2 in female: mostly smooth, with scattered punctures or shallow rugulae, finely punctate throughout. Sculpture of marginal depression of S 3 in female: mostly smooth, with scattered punctures or shallow rugulae, finely punctate throughout. 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: not extending beyond apex of T6 and not 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: foveolate. Sculpture of lateral S 4 in male: foveolate. Sculpture of medial S 5 in male: smooth. Sculpture of lateral S 5 in male: foveolate.

Diagnosis. Oreiscelio alluaudi is similar to O. rostratus and O. naevus . Oreiscelio alluaudi is the only species from Madagascar with a preocellar pit (Fig. 15) present in females, and this character allows it to be separated from females of both O. rostratus and O. naevus . It may also be distinguished from O. rostratus by the sculpture of the dorsal metasoma (Fig. 36). Males of O. alluaudi may be separated from those of O. naevus by the sculpture of the ventral mesepisternum which is coarsely foveate in the former and mostly to entirely smooth in the latter.
