Description. General: Body color: dark brown to black.

Antenna: Color of antennae in female: A1, A3–A6 dark brown; A2 yellow; A7– A12 black. Seta on pedicel of antenna in female: present, reaching to apex of A3.

Head: Color of setae on the head: yellow. Sculpture of dorsal frons between frontal carina and median ocellus: coarsely foveate, areolate. Preocellar pit in females: absent. Transverse rugae at vertex: absent. Sculpture of posterior vertex: areolate. Sculpture of occipital rim: areolate. Interantennal process: simple. Number of anteriorly projecting setae on anteclypeus: 8. Color of mandibles in female: brown throughout with teeth black. Mandibular teeth in female: ventral tooth at least twice as long and wide at base than dorsal tooth. 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, coarsely and irregularly punctate. Shape of anteclypeus: concave medially, with points laterally.

Legs: Color of legs: coxae and femora dark brown, trochanters, tibia and tarsi yellowish-brown.

Mesosoma: Sculpture of dorsal pronotum: areolate. Color of setae on the dorsal mesosoma: yellow. Sculpture of medial mesoscutum: areolate. Sculpture of lateral mesoscutum: same as medial mesoscutum with a subtle confusion of sculptural elements. Notaulus in female: absent. Parapsidal line: delimited. Sculpture of scutellum: areolate. Median furrow on scutellum: absent, present as a weak indentation. Posterior margin of scutellum: emarginate. 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: nearly straight, perpendicular to lateral margin of propodeal shelf. Sculpture of ventral pronotum: foveate reticulate, becoming smooth at anterolateral corner. Anterior pronotal pit: small, large. Pronotal cervical sulcus: poorly defined. Mesepimeral sulcus: indicated

by dorsoventral line of foveae. Sculpture of femoral depression in female: anterior half smooth, posterior half finely foveate. Mesopleural carina: indicated by one or two rows of punctures. Sculpture of ventral mesepisternum: foveate, irregularly areolate. Pilosity of metapleural triangle in female: present as many short fine white setae. Sculpture of ventral area of metapleuron: smooth.

Metasoma: Submarginal ridge on T1: percurrent, well-defined. Sublateral carina on T2: percurrent. Sculpture of T2–T3: reticulate rugose. Sculpture of T4: reticulate rugose. 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. 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: effaced to smooth. Sculpture of lateral S 3 in female: foveolate. Sculpture of lateral S 4 in female: reticulate rugose, foveolate. Sculpture of lateral S 5 in female: reticulate rugose. Sculpture of marginal depression of S 2 in female: mostly smooth, with scattered punctures or shallow rugulae, smooth. Sculpture of marginal depression of S 3 in female: mostly smooth, with scattered punctures or shallow rugulae. 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.

Diagnosis. Oreiscelio majikununuensis is most similar to Oreiscelio cultrarius in general appearance. Th e females may be separated from all other species of Oreiscelio by the straight posterior margin of the propodeum ( Fig. 76 ). Th e long ventral mandibular tooth ( Figs 77, 78 ) represents the largest size difference between mandibular teeth in Oreiscelio .

Etymology. The type specimen was collected in an isolated patch of Afromontane forest on a mountain called Maji Kununua, which is Swahili for “place of water”.
