Body length of male: 3.0 mm (n=1). Body color: black. Antenna: Color of antennae in female: A1–A6 pale brown; A7–A12 dark brown. Color of antennae in male: A1–A2 brown; A3–A12 yellow. Seta on pedicel of antenna in female: present, not reaching apex of A3. Head: Color of setae on the head: yellow. Sculpture of dorsal frons between frontal carina and median ocellus: coarsely foveate. Preocellar pit in females: indicated by a small round depression. Transverse rugae at vertex: present. Sculpture of posterior vertex: coarsely foveate. Sculpture of occipital rim: areolate. Interantennal process: simple. Number of anteriorly projecting setae on anteclypeus: 6. Color of mandibles in male: basal half black, apical half brown. Color of mandibles in female: brown throughout. 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 large punctures. Shape of anteclypeus: striplike, straight to slightly convex. Legs: Color of legs: coxae brown, legs otherwise yellow. Mesosoma: Sculpture of dorsal pronotum: areolate. Color of setae on the dorsal mesosoma: yellow. Sculpture of medial mesoscutum: areolate. Sculpture of lateral mesoscutum: with small patch of smoother sculpture, formed by fusion of sculptural ridges, smooth patch not extending to scutoscutellar sulcus. Notaulus in female: absent. Parapsidal line: delimited. Sculpture of scutellum: areolate. Median furrow on scutellum: present as a weak indentation, present as a distinct furrow reaching from posterior to anterior margin. 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. 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. Pronotal cervical sulcus: well defined by contiguous punctures. Mesepimeral sulcus: indicated by dorsoventral line of foveae. Sculpture of femoral depression in female: smooth throughout. Sculpture of femoral depression in male: anterior half smooth, posterior half finely foveate. Mesopleural carina: indicated by one or two rows of punctures, 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. Pilosity of metapleural triangle in male: present as many short fine white setae. Sculpture of ventral area of metapleuron: foveate reticulate, foveate reticulate, with slightly appressed ridges. Metasoma: Submarginal ridge on T1: percurrent, well-defined. Sublateral tergal carina on T2: absent. Sculpture of T2–T3: reticulate rugose. Sculpture of T4: longi-tudinally 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: straight to slightly concave, with small points laterally. Longitudinal medial keel on S1: absent. Sculpture of medial S 2 in female: punctate. 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: smooth. Sculpture of lateral S 4 in female: smooth. Sculpture of lateral S 5 in female: reticulate rugose, punctate crenulate. Sculpture of marginal depression of S 2 in female: 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, mostly smooth with scattered punctures. Apical spine on S 6 in female: not extending beyond apex of T6 and not visible in dorsal view. Sculpture of medial S 2 in male: punctate. Sculpture of medial S 3 in male: smooth. Sculpture of lateral S 3 in male: smooth. Sculpture of lateral S 4 in male: smooth. Sculpture of medial S 5 in male: smooth. Sculpture of lateral S 5 in male: smooth. <b>Diagnosis.</b> <i>Oreiscelio sechellensis</i> is similar to <i>Oreiscelio zuzkae</i>, from which it differs most obviously in the sculpture of the sternites; the sternites of <i>O. sechellensis</i> are largely smooth (Figs 23, 120) while those of <i>O. zuzkae</i> are longitudinally reticulate (Fig. 138). Th e only other species with similarly reduced sculpture of the ventral metasoma is <i>Oreiscelio rugosus</i>. Females of <i>O. rugosus</i> have a spine on S6 that is visible in dorsal view (Fig. 108) whereas females of <i>O. sechellensis</i> do not (Fig. 118). <b>Link to distribution map.</b> <b> 58</b> <b>Material examined.</b> Holotype female: <b>SEYCHELLES</b>: Percy Sladen Trust Expedition. 1930-170. B.M. TYPE HYM. 9.507 (BMNH) <b> 59</b> . <i>Paratypes</i>: <b>SEYCHELLES</b>: 7 females, BMNH #790246 (OSUC 253194-253199), BMNH #790247 (OSUC 253194) (BMNH) <i>Other material</i>: <b>SEYCHELLES</b>: 1 male, 9 females, OSUC 207594, 234295-234392 (CNCI). <b>Comments.</b> <i>Oreiscelio sechellensis</i> was originally described from only female specimens; one male is included in this revision.
