Description. General: Body length of female: 3.1-4.1 mm (n=15). Body length of male: 3.6-3.8 mm (n=6). Body color: black.

Antenna: Color of antennae in female: A1–A6 yellow; A7–A12 dark brown to black. Color of antennae in male: A1–A2 brown; A3–A12 variably becoming yellow apically, antennomeres often yellow ventrally. Seta on pedicel of antenna in female: present, reaching past apex of A3.

Head: Color of setae on the head: yellow. Sculpture of dorsal frons between frontal carina and median ocellus: coarsely foveate, foveate with contiguous cells. Preocellar pit in females: absent. Transverse rugae at vertex: present. Sculpture of posterior vertex: coarsely foveate. Sculpture of occipital rim: coarsely foveate, cells often contiguous.. Interantennal process: simple. Number of anteriorly projecting setae on anteclypeus: 6. Color of mandibles in male: yellow throughout, teeth brown. Color of mandibles in female: yellow throughout with teeth brown. Mandibular teeth in female: dorsal tooth larger. Sculpture of ventral gena anterior to genal carina: row of contiguous punctures, row of well separated punctures. Sculpture of ventral gena posterior to genal carina: mostly smooth, with sparse large punctures, coarsely and irregularly punctate. Shape of anteclypeus: striplike, straight to slightly convex.

Legs: Color of legs: entirely yellow.

Mesosoma: Sculpture of dorsal pronotum: areolate with expanded ridges. Color of setae on the dorsal mesosoma: yellow. Sculpture of medial mesoscutum: coarsely foveate. Sculpture of lateral mesoscutum: with an elevated patch of smoother sculpture, bounded by mesoscutal humeral sulcus laterally, extending to scutoscutellar sulcus posteriorly. Notaulus in female: present. Parapsidal line: delimited. Sculpture of scutellum: coarsely foveate. Median furrow on scutellum: absent. Posterior margin of scutellum: convex. Outer projection of the propodeum: present as distinct corner or

posteriorly projecting spine. Posterior margin of propodeal shelf between inner and outer propodeal projections in female: concave. Posterior margin of propodeal shelf between inner and outer propodeal projections in male: concave. Sculpture of ventral pronotum: foveate reticulate, becoming smooth at anterolateral corner. 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: smooth throughout. Sculpture of femoral depression in male: smooth medially, bounded by small foveae. Mesopleural carina: indicated by one or two rows of punctures. Sculpture of ventral mesepisternum: with smooth area surrounded by small foveae. 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: smooth.

Metasoma: Submarginal ridge on T1: absent. Sublateral tergal carina on T2: percurrent. Sculpture of T2–T3: longitudinally striate. Sculpture of T4: longitudinally striate. Sculpure of T5: longitudinally strigose. Shape of subapical T 6 in female in dorsal view: semicircular, width along anterior margin twice the length.. Apex of T 7 in male: slightly convex. Longitudinal medial keel on S1: absent. Sculpture of medial S 2 in female: unknown. Sculpture of medial S 3 in female: longitudinally strigose, effaced to smooth. Sculpture of medial S 4 in female: longitudinally strigose, effaced to smooth. Sculpture of medial S 5 in female: longitudinally strigose, effaced to smooth. Sculpture of lateral S 3 in female: longitudinally strigose. Sculpture of lateral S 4 in female: longitudinally strigose. Sculpture of lateral S 5 in female: longitudinally strigose. Sculpture of marginal depression of S 2 in female: smooth. Sculpture of marginal depression of S 3 in female: smooth. Sculpture of marginal depression of S 4 in female: mostly smooth with scattered punctures or shallow rugulae, 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: longitudinally strigose. Sculpture of medial S 3 in male: smooth, weakly longitudinally strigose. Sculpture of lateral S 3 in male: longitudinally strigose. Sculpture of lateral S 4 in male: longitudinally strigose. Sculpture of medial S 5 in male: smooth, longitudinally strigose. Sculpture of lateral S 5 in male: longitudinally strigose.

Diagnosis. Oreiscelio scapularis is most similar to O. rostratus . It may be separated from all other species of Oreiscelio on the basis of the shape of T6 alone (Figs 21, 114).

Etymology. The epithet scapularis refers to the large smooth areas of the lateral mesoscutum.
