Description
Female holotype (Fig. 2)
Morphology. Body length 8.2 mm (paratype: 7.3 mm). Flagellum with 31 (paratype: 28) flagellomeres, long and filiform; 1st flagellomere 4.2x as long as wide; 3rd flagellomere 3.9x as long as wide; pre-apical flagellomere 1.1x as long as wide. Temple short, strongly and almost linearly narrowed behind eye, ca. 0.4x as wide as eye (Fig. 2 c). Distance of lateral ocellus to eye 0.9x ocellar diameter. Frons and vertex granulate, dull. Face finely punctate and granulate, dull. Clypeus with some coarse setiferous punctures and basal transversal ridge. Malar space 0.6x as long as width of mandibular base. Mandible slender; upper tooth longer than lower one. Maxillary palps very long, 2nd palpomere about as long as 3rd hind tarsomere. Genal carina reaching hypostomal carina away from mandibular base; both carinae low.
Mesosoma covered with grey setae. Mesoscutum finely punctate and granulate, dull. Notaulus not impressed. Mesopleuron smooth, with band of fine longitudinal striation dorsally and rather dense setiferous punctures ventrally, speculum smooth and shining (Fig. 2 e). Metapleuron punctate; juxtacoxal carina absent. Scutellum moderately elevated, longer than wide, punctate, with lateral carina in basal 0.2. Propodeum completely carinate, mainly and finely rugose, area petiolaris smoothened. Area basalis trapezoid, 1.5x longer than wide. Area superomedia almost rectangular, 1.3x as long as wide, apical carina weak or absent; anterior transverse carina (costula) reaching at its basal third (Fig. 2 b). Apical transversal carina slightly lamelliform elevated at posterolateral edge of area dentipara. Hind femur 3.9x as long as wide; hind tibia 4.6x as long as wide, apical spurs curved apically. Hind tarsus 1.75x as long as hind tibia. Claws simple, strongly curved ca. 90° apically.
Areolet rhombic, pointed or shortly sessile frontally; vein 2m-cu slightly distal to its middle. Vein 1cu-a interstitial. Nervellus of hind wing slightly inclivous.
Metasoma rather slender, mainly smooth and shining. 1st tergite 2.4x longer than wide; postpetiole with fine longitudinal striae, especially on lateral fields. 2nd tergite 1.25x wider than long, without lateral carina. Thyridium oval, situated at basal margin of 2nd tergite. 2nd and 3rd tergites with some fine setiferous punctures laterally. 2nd and 3rd sternites with median folds. Ovipositor sheath stout and wide.
Colour. Black. Scape, pedicel and two basal flagellomeres yellowish; following flagellomeres black; flagellomeres 10-17 with ivory stripes or rings. Palps, fore and mid-coxae, all trochanters and hind tarsus, except black base of hind metatarsus, ivory. Tegula, scutellum and postscutellum yellowish. Hind margin of mesopleuron, entire metapleuron and propodeum red. Metasoma black; petiolus partly reddish-brown dorsally; post-petiolus, 2nd and 3rd tergites with yellowish bands in apical halfs; 2nd and 3rd sternites yellowish. Fore and mid-femora, tibiae and tarsi pale yellowish; hind coxa reddish-yellow, with brown lateral stripe; hind femur red or chestnut-red; hind tibia blackish, with cream-yellow sub-basal stripe. Wings hyaline; pterostigma ochreous.
Diagnosis
The species runs to O. kamikochianus (Momoi, 1965) in the key of Kasparyan et al. (2014), but can been separated by the different colour of the propodeum and the metasoma.
Male
Unknown
