Body length of male: 3.4-3.9 mm (n=5). Body color: black. Antenna: Color of antennae in female: dark brown to black throughout, A1–A6 yellow; A7–A12 dark brown to black. Color of antennae in male: A1–A2 brown; A3–A12 variably becoming yellow apically, antennomeres often yellow ventrally. 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: coarsely foveate, areolate. Preocellar pit in females: absent. Transverse rugae at vertex: present. Sculpture of posterior vertex: areolate, coarsely foveate. 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 male: yellow throughout, teeth brown. Color of mandibles in female: yellow throughout with teeth brown. Mandibular teeth in female: dorsal tooth larger. Sculpture of ventral gena anterior to genal carina: row of contiguous punctures, row of well separated punctures. Sculpture of ventral gena posterior to genal carina: mostly smooth, with sparse large punctures, coarsely and irregularly punctate. Shape of anteclypeus: striplike, straight to slightly convex. Legs: Color of legs: entirely yellow. Mesosoma: Sculpture of dorsal pronotum: areolate, areolate with expanded ridges. Color of setae on the dorsal mesosoma: yellow. Sculpture of medial mesoscutum: coarsely foveate. Sculpture of lateral mesoscutum: with an elevated patch of smoother sculpture, bounded by mesoscutal humeral sulcus laterally, extending to scutoscutellar sulcus posteriorly. Notaulus in female: present. Parapsidal line: delimited. Sculpture of scutellum: coarsely foveate. Median furrow on scutellum: absent. Posterior margin of scutellum: convex. 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: mostly smooth with small foveolae around antespiracular patch. Anterior pronotal pit: large. 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: smooth throughout. Mesopleural carina: indicated by one or two rows of punctures. Sculpture of ventral mesepisternum: with smooth area surrounded by small foveae. Pilosity of metapleural triangle in female: glabrous or with at most 3 small setae. Pilosity of metapleural triangle in male: absent, present as many short fine white setae. Sculpture of ventral area of metapleuron: smooth, foveate reticulate, with slightly appressed ridges. Metasoma: Submarginal ridge on T1: absent. Sublateral tergal carina on T2: percurrent. Sculpture of T2–T3: longitudinally striate. Sculpture of T4: longitudinally strigose. Sculpure of T5: 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: slightly convex. Longitudinal medial keel on S1: present. 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, foveolate. Sculpture of lateral S 4 in female: foveolate. Sculpture of lateral S 5 in female: reticulate rugose, foveate. Sculpture of marginal depression of S 2 in female: rugulose, smooth. Sculpture of marginal depression of S 3 in female: smooth, 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: not extending beyond apex of T6 and not visible in dorsal view. Sculpture of medial S 2 in male: punctate reticulate, reticulate rugose. Sculpture of medial S 3 in male: smooth, longitudinally reticulate. Sculpture of lateral S 3 in male: reticulate rugose, foveolate. Sculpture of lateral S 4 in male: foveolate, reticulate rugose. Sculpture of medial S 5 in male: smooth. Sculpture of lateral S 5 in male: foveolate, reticulate rugose. <b>Diagnosis.</b> <i>Oreiscelio rostratus</i> is most similar to <i>O. scapularis</i> and <i>O. alluaudi</i>. It can be distinguished from <i>O. scapularis</i> by the shape of T6 (Figs 98) and from <i>O. alluadi</i> by the lack of a preocellar pit. The flange above the interantennal process usually serves well to identify this species from other Madagascan species but exhibits sufficient variability that it should always be used in conjunction with other characters. <b>Etymology.</b> The epithet <i>rostratus</i>, meaning “beaked”, refers to the dorsal flange of the interantennal process in this species. <b>Link to distribution map.</b> <b> 49</b> <b>Material examined.</b> Holotype female: <b>MADAGASCAR</b>: 12°30’52”S 49°10’53”E, Prov. d’Antsiranana, Parc Nat.
