Re-description. Female (holotype).

Head. In dorsal view, 1.8× as wide as long, 1.3× as wide as mesoscutum, smooth, with temple rounded behind eyes. Eye in lateral view 1.5× as high as wide and 1.5× as wide as temple medially. POL 0.8× OD; OOL 3.1× OD. Face 1.3× as wide as high, with spared setae laterally, almost entirely smooth; inner margins of eyes subparallel. Clypeus 2.3× as wide as high, almost straight ventrally. Paraclypeal fovea small, not reaching half distance between clypeus and inner border of eye. Mandible almost parallel-sided, about as long as its maximum width; its middle tooth rather wide and rather long, directed forwards, lower tooth evenly curved on outside margin. Antenna 31-segmented. Scape 2.0× as long as pedicel. First flagellomere 2.8× as long as its maximum width, 1.3× as long as second flagellomere. Second to 24th flagellomeres 1.7–1.9×, 25th to 28th segments 2.2×, and 29th (apical) flagellomere 3.3× as long as their maximum width.

Mesosoma . In lateral view 1.1× as long as high. Mesoscutum (dorsal view) 0.7× as long as its maximum width, smooth, sparsely setose along notaulus and laterally. Notaulus wide, crenulated, present on all horizontal surface of mesoscutum reaching mesoscutal pit. Mesoscutal pit present, wide, short, oval, smooth, about as long as its maximum width. Prescutellar depression (scutellar sulcus) smooth, with median carinae, about as long as its maximum width. Precoxal sulcus present, hardly crenulate, almost reaching anterior margin of mesopleuron. Posterior mesopleural furrow crenulate below. Propodeum rugose with pentagonal areola delineated by distinct carinae, with almost smooth basolateral areas. Propodeal spiracles very small, its diameter 0.2× as large as distance from spiracle to anterior margin of propodeum.

Wings. Length of fore wing 2.7× its maximum width. Marginal cell ending on apex of wing, 4.2× as long as its maximum width. Vein 3-SR 1.6× as long as vein 2-SR. Vein SR1 2.6× as long as vein 3-SR. Vein r longer than pterostigma width. First subdiscal cell 3.3× as long as its maximum width. Hind wing 5.6× as long as its maximum width.

Legs. Hind femur 4.1× as long as its maximum width. Hind tibia weakly widened to apex, 7.3× as long as its maximum subapical width, 1.1× as long as hind tarsus. First tarsomere of hind tarsus 1.8× as long as second tarsomere.

Metasoma. First tergite weakly evenly widened towards apex, 1.6× as long as its apical width, entirely striate with rugulosity between striae. Ovipositor 0.9× as long as first tergite, 0.3× as long as metasoma, 0.7× as long as hind femur.

Colour. Body, mandible, flagellar segments of antenna and pterostigma brown to dark brown. Legs yellow. First metasomal tergite similar colour to second and third tergites. Wings almost hyaline.

Length. Body 2.6 mm, fore wing 2.6 mm, hind wing 1.8 mm.

Variation. Body length 2.3–2.6 mm, fore wing length 2.3–2.6 mm, hind wing length 1.7–1.8 mm. Antenna 30–31-segmented. First flagellomere 2.6–2.8× as long as its maximum width. Second flagellomere 2.0–2.3× as long as its maximum width. Clypeus 2.3–2.5× as wide as high. Vein 3-SR 1.6–1.7× as long as vein 2-SR. Vein SR1 2.5–2.6× as long as vein 3-SR. First metasomal tergite 1.5–1.6× as long as its apical width.

Male. Unknown.

Comparative diagnosis. This species is similar to O. (P.) glabrifaciale Fischer 2004 ( Cambodia) ; differences between these species are described under the latter species.

Distribution. Sri Lanka, Vietnam.
