Description. General: Body length of female: 2.9-3.3 mm (n=5). Body color: black.

Antenna: Color of antennae in female: dark brown to black throughout. Seta on pedicel of antenna in female: present, reaching past apex of A3.

Head: Color of setae on the head: brown. Sculpture of dorsal frons between frontal carina and median ocellus: areolate. Preocellar pit in females: present as a distinct pit. Transverse rugae at vertex: present. Sculpture of posterior vertex: areolate. Sculpture of occipital rim: areolate. Interantennal process: diverging into two carinae that extend laterally along surface of frons. Number of anteriorly projecting setae on anteclypeus: 6. Color of mandibles in female: basal half black; apical half dark 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. Sculpture of ventral gena posterior to genal carina: coarsely and irregularly punctate. Shape of anteclypeus: striplike, straight to slightly convex.

Legs: Color of legs: dark brown, tarsi and distal portion of tibiae light brown.

Mesosoma: Sculpture of dorsal pronotum: areolate. Color of setae on the dorsal mesosoma: brown. Sculpture of medial mesoscutum: areolate. Sculpture of lateral mes-oscutum: 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. 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: indicated by dorsoventral line of foveae. Sculpture of femoral depression in female: finely foveate throughout. Mesopleural carina: present as one or two carinae. Sculpture of ventral mesepisternum: irregularly areolate. Pilosity of metapleural triangle in female: present as many short fine white setae. Sculpture of ventral area of metapleuron: foveate reticulate. Sculpture of dorsal propodeum (removed from use): with large cells medially.

Metasoma: Submarginal ridge on T1: percurrent, well-defined. Sublateral 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. Longitudinal medial keel on S1: absent. Sculpture of medial S 2 in female: punctate reticulate. 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. Sculpture of lateral S 4 in female: reticulate rugose. 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: mostly smooth, with scattered punctures or shallow rugulae, 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.

Diagnosis. Oreiscelio gryphus is most similar to specimens of Oreiscelio coracinus from Cameroon and Nigeria. It may be separated from them by the presence of infuscate wings and brown setae on the head and dorsal mesosoma ( Figs 55, 57 ). Additionally, the frons of O. coracinus ( Figs 47 ) has a more transverse shape in frontal view than that of O. gryphus ( Fig. 59 ).

Etymology. The epithet gryphu s, a fantastic creature, refers to the presence of many distinctive characters in this species.
