Sculpture of posterior vertex: areolate. Sculpture of occipital rim: areolate. Interantennal process: extended dorsally into medial flange, flange reaching from near apex of interantennal process to frons. Number of anteriorly projecting setae on anteclypeus: 6. Color of mandibles in female: basal half black; apical half pale brown. Mandibular teeth in female: teeth of equal size. Sculpture of ventral gena anterior to genal carina: row of shallow areolae with reduced ridges between cells. Sculpture of ventral gena posterior to genal carina: areolate, irregularly rugose.

Sculpture of scutellum: areolate. Median furrow on scutellum: present as a weak indentation. Posterior margin of scutellum: deeply notched. 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. Sculpture of ventral pronotum: foveate reticulate, becoming smooth at anterolateral corner. Anterior pronotal pit: small. Pronotal cervical sulcus: well defined by contiguous punctures. Mesepimeral sulcus: crenulate. Sculpture of femoral depression in female: transversely striate throughout, finely foveate throughout. Mesopleural carina: present as one or two carinae. Sculpture of ventral mesepisternum: with smooth area surrounded by small foveae. Pilosity of metapleural triangle in female: present as many short fine white setae. Sculpture of ventral area of metapleuron: foveate reticulate, with slightly appressed ridges.

Metasoma: Submarginal ridge on T1: absent. Sublateral carina on T2: percurrent. 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. Longitudinal medial keel on S1: absent. Sculpture of medial S 2 in female: punctate reticulate. Sculpture of medial S 3 in female: foveate, effaced to smooth. Sculpture of medial S 4 in female: effaced to smooth. Sculpture of medial S 5 in female: longitudinally strigose. Sculpture of lateral S 3 in female: punctate crenulate. Sculpture of lateral S 4 in female: punctate crenulate. Sculpture of lateral S 5 in female: punctate crenulate. 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: not extending beyond apex of T6 and not visible in dorsal view, extending beyond apex of T6 and visible in dorsal view.

Diagnosis. Oreiscelio zulu appears to be limited in distribution to the eastern part of South Africa. It is similar in habitus to O. turneri , O. coracinus , and O. badius but lacks divergent carinae on the frons above the interantennal process and instead bears a dorsal flange. Among the continental species the dorsally enlarged interantennal process is similar to that of O. iommii , which is easily distinguishable from O. zulu by its entirely smooth mesopleuron.

Etymology. Oreiscelio zulu is named for the Zulu people that inhabit the eastern region of South Africa where this species is found.
