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.

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. Link to distribution map. 19 Material examined.
