Description. General: Body length of female: 2.42 mm (n=1). 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: yellow. Sculpture of dorsal frons between frontal carina and median ocellus: areolate. Preocellar pit in females: indicated by a small round depression. Transverse rugae at vertex: present. 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 dark 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: mostly smooth, with sparse small punctures. 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: shallowly areolate. Color of setae on the dorsal mesosoma: yellow. Sculpture of medial mesoscutum: shallowly areolate, becoming smooth posteriorly. Sculpture of lateral mesoscutum: smooth throughout. Notaulus in female: absent. Parapsidal line: delimited. Sculpture of scutellum: areolate. Median furrow on scutellum: absent. 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: obliterated. Anterior pronotal pit: absent. Pronotal cervical sulcus: poorly defined. Mesepimeral sulcus: indicated by a row of faint and shallow depressions. Sculpture of femoral depression in female: smooth throughout. Mesopleural carina: absent. Sculpture of ventral mesepisternum: smooth. 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: present in anterior half. Sculpture of T2–T3: weakly rugulose. Sculpture of T4: weakly rugulose. Sculpure of T5: weakly rugulose. 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: longitudinally strigose. Sculpture of lateral S 3 in female: smooth. Sculpture of lateral S 4 in female: rugulose. Sculpture of lateral S 5 in female: longitudinally strigose. Sculpture of marginal depression of S 2 in female: finely punctate throughout. Sculpture of marginal depression of S 3 in

female: finely punctate throughout. 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 magnipennis is most similar to larger specimens of O. coracinus and O. gryphus . It is best identified by the length of its wings ( Fig. 72 ) and the large preocellar pit (as Fig. 17). Some specimens of O. rostratus have the wings extending well beyond the apex of the metasoma, but this species has yellow legs (Fig. 97), lacks a preocellar pit and is found only in Madagascar. Oreiscelio magnipennis has brown legs ( Fig. 67 ) and its distribution is limited to continental Africa.

Etymology. The epithet magnipennis , meaning “large wing”, refers to the large size of the wings in this species.
