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: absent, small. Pronotal cervical sulcus: poorly defined. Mesepimeral sulcus: indicated by dorsoventral line of foveae, crenulate. Sculpture of femoral depression in female: smooth throughout, transversely striate throughout, anterior half smooth, posterior half finely foveate. Sculpture of femoral depression in male: smooth throughout, finely foveate throughout, with weak transverse striae throughout, anterior half smooth, posterior half finely foveate. Mesopleural carina: present as one or two carinae. Sculpture of ventral mesepisternum: foveate, 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, foveate reticulate, foveate reticulate, with slightly appressed ridges.

Metasoma: Submarginal ridge on T1: percurrent, well-defined, indicated by an irregular ridge, absent. Sublateral carina on T2: absent, present in anterior half. Sculp-ture of T2–T3: reticulate rugose. Sculpture of T4: longitudinally strigose, reticulate rugose. Sculpure of T5: longitudinally strigose, 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: bispinose. Longitudinal medial keel on S1: absent, present. 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: punctate crenulate, rugulose. Sculpture of lateral S 4 in female: longitudinally strigose, rugulose, punctate crenulate. 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: smooth. Sculpture of marginal depression of S 4 in female: mostly smooth with scattered punctures or shallow rugulae. 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, foveolate. Sculpture of medial S 3 in male: smooth, foveate. Sculpture of lateral S 3 in male: longitudinally strigose, foveolate. Sculpture of lateral S 4 in male: rugulose, longitudinally strigose, foveolate. Sculpture of medial S 5 in male: smooth, foveate. Sculpture of lateral S 5 in male: foveolate, longitudinally strigose, reticulate rugose, rugulose.

Diagnosis. Oreiscelio turneri is most similar in general appearance to Oreiscelio coracinus and Oreiscelio badius . Oreiscelio turneri is separated from both of these species by the much larger ventral mandibular tooth (Figs 41, 42). Th e specimens from Kenya, Tanzania, and Uganda tend to be smaller and darker in color than those found in Zimbabwe and South Africa.
