Description. General: Body length of female: 2.2-2.4 mm (n=20). Body length of male: 2.2 mm (n=1). Body color: dark brown to black, metasoma often lighter than head and mesosoma.

Antenna: Color of antennae in female: pale brown throughout. 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: white. Sculpture of dorsal frons between frontal carina and median ocellus: areolate, areolate, effaced medially. Preocellar pit in females: absent, indicated by a small round depression. Transverse rugae at vertex: present. Sculpture of posterior vertex: areolate. Sculpture of occipital rim: areolate. Interantennal process: simple. Number of anteriorly projecting setae on anteclypeus: 6. Color of mandibles in male: basal half black; apical half pale brown. Color of mandibles in female: yellow throughout with teeth brown. Mandibular teeth in female: teeth of equal size, ventral tooth larger, but less than 2 times as long as dorsal tooth. Sculpture of ventral gena anterior to genal carina: row of areolae, dorsoventrally rugose. Sculpture of ventral gena posterior to genal carina: areolate, mostly smooth, with sparse large punctures. Shape of anteclypeus: striplike, straight to slightly convex.

Legs: Color of legs: brown, tarsi and distal portion of tibiae yellow, brown, distal portion of tibiae and tarsomeres 1-4 yellow, apical tarsomere brown.

Mesosoma: Sculpture of dorsal pronotum: areolate. Color of setae on the dorsal mesosoma: white. Sculpture of medial mesoscutum: areolate, areolate, with pronounced longitudinal ridges. Sculpture of lateral mesoscutum: same as medial mesoscutum with a subtle confusion of sculptural elements. Notaulus in female: absent. Parapsidal line: indistinguishable. Sculpture of scutellum: areolate. Median furrow on scutellum: absent, present as a weak indentation. Posterior margin of scutellum: emarginate, 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: nearly straight. Sculpture of ventral pronotum: foveate reticulate, becoming smooth at anterolateral corner, mostly smooth with longitudinal rugulae ventrally. Anterior pronotal pit: absent, small. Pronotal cervical sulcus: poorly defined, well defined by contiguous punctures. Mesepimeral sulcus: indicated by dorsoventral line of foveae, crenulate. Sculpture of femoral depression in female: anterior half smooth, posterior half longitudinally striate. Sculpture of femoral depression in male: smooth throughout, with weak transverse striae throughout. Mesopleural carina: present as one or two carinae, weakly defined by fine ridges. Sculpture of ventral mesepisternum: with smooth area surrounded by small foveae. Pilosity of metapleural triangle in female: present as many short fine white setae. Pilosity of metapleural triangle in male: present as many short fine white setae. Sculpture of ventral area of metapleuron: smooth

Metasoma: Submarginal ridge on T1: indicated by an irregular ridge, absent. Sublateral tergal carina on T2: absent. Sculpture of T2–T3: reticulate rugose. Sculpture of T4: longitudinally strigose. Sculpure of T5: longitudinally strigose. 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: straight to slightly concave, with small points laterally. Longitudinal

medial keel on S1: absent. Sculpture of medial S 2 in female: reticulate rugose. 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: reticulate rugose, longitudinally strigose. Sculpture of lateral S 4 in female: reticulate rugose, longitudinally strigose. Sculpture of lateral S 5 in female: reticulate rugose. Sculpture of marginal depression of S 2 in female: rugulose. 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 View Figures 37-42.92 ) 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 View Figures 37-42.92 ). 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.
