Description
Female. Body length 3.8 mm (n=1).
Radicle color: same color as scape. Scape color: Yellowish. A4: longer than broad. A5: broader than long. Antennal club: formed, segments compact.
Interantennal process: not elongate. Median longitudinal elevation in frontal depression: absent. Frontal depression: concave. Frontal depression sculpture: with 3 or more broadly interrupted transverse carinae. Submedian carina: strong, formed by a sharp raised carina. Submedian carina medially: without peak. Concavity across dorsal part of frontal depression: absent. Depression extending ventrally from median ocellus: absent. Upper frons: not hood-like. Malar area near antennal foramen: with oblique tooth-like flange (facial nubbin). Malar area at mouth corner: with one carina. Smooth strip along posterior side of malar sulcus: present, broad throughout its length. Middle genal carina: present. Direction of middle genal carina dorsally: parallel to eye margin. Major sculpture of gena anteriorly: umbilicate-foveate; rugose. Major sculpture of gena posteriorly: umbilicate-foveate; rugose. Microsculpture of gena anteroventrally: absent. Microsculpture of gena posteroventrally: absent. Median carina extending posteriorly from hyperoccipital carina: absent. Hyperoccipital carina: indicated by rugae. Lateral connection between hyperoccipital and occipital carinae: absent. Area between vertex and occipital carina: umbilicate-foveate; irregularly rugose. Occipital carina medially: absent. Lateral corners of occipital carina: sharp and protruding.
Lateral pronotal area: without bulge projecting towards anterior pit. Epomial corner: strong. Netrion surface anteriorly: not inflexed. Mesoscutum anteriorly: not steep. Mesoscutal median carina: present and complete. Longitudinal carina between median carina and notauli: absent. Major sculpture of medial mesoscutum anteriorly: umbilicate-foveate. Major sculpture of medial mesoscutum posteriorly: umbilicate-foveate. Microsculpture of medial mesoscutum anteriorly: granulate. Microsculpture of medial mesoscutum posteriorly: absent. Major sculpture of mesoscutellum: umbilicate-foveate; irregularly rugose. Microsculpture of mesoscutellum medially: punctate. Microsculpture of mesoscutellum laterally: punctate. Mesoscutellar apex: convex or straight. Setae along anterior limit of femoral depression: arising from rows of foveae. Number of carinae crossing speculum above femoral depression: 2. Number of carinae crossing femoral depression: more than 5. Mesepimeral sulcus pits: 3-5. Metascutellum dorsally: flat. Metascutellar sculpture dorsally: with scattered rugae. Median carina of metascutellum: absent or branched. Metascutellar setae: absent. Metascutellar apex: convex or straight. Metapleuron above ventral metapleural area: crossed by carinae. Metasomal depression setae: absent. Lateral propodeal carinae anteromedially: strongly diverging. Anterior areoles of metasomal depression: absent. Anterior longitudinal carinae in metasomal depression: absent. Lateral propodeal areas: separated medially. Postmarginal vein: present. Fore wing apex: reaching middle of T5.
T1 midlobe: obscured by other raised sculpture. T1: with long anterior bulge, reaching metascutellum. T2: with straight longitudinal striae or rugae. T6: longer than broad. Apical flange of T6: exposed apically. Metasomal apex: rounded. Major sculpture of T6: umbilicate-punctate. Microsculpture of T6: granulate.
Male. Body length 3.9 mm (n=1). A5 tyloid: carina-like, not expanded. Median tooth of frontal depression: absent. Median lobe of T1: with 5 longitudinal carinae. Metasomal apex: with acuminate lateral corners.
Diagnosis
Male: Face with oblique expanded flange between antennal foramen and eye. Gena with 1 strong middle carina. Metascutellum flat, with some rugae but only slightly broader than long. T1 midlobe with 5 longitudinal carinae. T7 with acuminate posterolateral corners.

Material examined
Neotype, male: INDONESIA: Jawa Tengah Prov., Java Isl., Semarang (Samarang), VII-1909, E. Jacobson, OSUC 436237 (deposited in RMNH). Other material: INDONESIA: 1 female, OSUC 448631 (RMNH).
Comments
The type material of Oxyscelio foveatus Kieffer, collected by E. Jacobson from Semarang, Java, could not be found after an extensive search of collections known to house Kieffer type material. The neotype of Oxyscelio foveatus is presently designated to clarify the taxonomic status of the genus and species. It was selected because of its collector, collection locality and date and because it agrees with Kieffer’s remarks on metascutellar sculpture of the lost holotype. It is possible that this specimen was collected during the same event as the lost holotype.
