Type material. Holotype: female, Cambodia, SW, 20 km SE Koh Kong, 11°34’N, 103°07’E, V.2005, 50– 300 m, Jendek and Saussa leg. ( NHMW).

Re-description. Female (holotype).

Head. In dorsal view, 1.8× as wide as long, 1.4× as wide as mesoscutum, smooth, with temple rounded behind eyes. Eye in lateral view 1.7× as high as wide and 1.8× as wide as temple medially. POL 0.7× OD; OOL 3.1× OD. Face 1.3× as wide as high, with very sparse setae laterally, almost entirely smooth; inner margins of eyes subparallel. Clypeus 2.3× as wide as high, slightly concave 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 wide and rather short, partly directed below, lower tooth evenly curved on outside margin. Antenna more than 22-segmented (apical flagellomeres missing). Scape 2.5× as long as pedicel. First flagellomere 2.7× as long as its maximum width, 1.1× as long as second flagellomere. Second flagellomere 2.3×, third segment 2.2×, fourth to 19th flagellomeres 2.0–2.1×, and 20th segment 1.9× 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. Notaulus wide, complete, reaching mesoscutal pit. Mesoscutal pit present, wide, short, oval, smooth, 1.4× as long as its maximum width. Prescutellar depression (scutellar sulcus) smooth, only with median carina, about as long as its maximum width. Precoxal sulcus narrow, oblique, curved below, smooth, reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow crenulate below. Propodeum almost completely rugose, smooth basally, without delineated 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 3.0× its maximum width. Marginal cell ending on apex of wing, 4.0× as long as its maximum width. Vein 3-SR 1.7× as long as vein 2-SR. Vein SR1 2.3× as long as vein 3-SR. Vein r longer than pterostigma width. First subdiscal cell 3.0× as long as its maximum width. Hind wing 4.5× as long as its maximum width.

Legs. Hind femur 3.5× as long as its maximum width. Hind tibia distinctly widened to apex, 6.1× as long as its maximum subapical width, about as long as hind tarsus. First tarsomere of hind tarsus 1.9× as long as second tarsomere.

Metasoma. First tergite weakly evenly widened towards apex, 1.4× as long as its apical width, striate with rugosity 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, head, mandible and pterostigma brown to dark brown. Antennal segments and legs light brown to yellow. First metasomal tergite similar colour to second and third tergites. Wings almost hyaline.

Length. Body 3.0 mm, fore wing 2.2 mm, hind wing 1.6 mm.

Male. Unknown.

Comparative diagnosis. This species is similar to O. (P.) multicarinatum Tobias 1990 ( Sri Lanka and Vietnam), but differs from it in having the eye in lateral view 1.8× as wide as temple medially (1.5× O. (P.) multicarinatum ), precoxal sulcus narrow, smooth, reaching posterior margin of mesopleuron (wide, crenulate and not reaching posterior margin of mesopleuron in O. (P.) multicarinatum ), propodeum without delineated areola (with delineated pentagonal areola in O. (P.) multicarinatum ), and hind femur 3.5× as long as its apical width (4.1× in O. (P.) multicarinatum ).

Distribution. Cambodia.
