Diagnosis.Distinguished from O. acuminataby the features given in the key.
Description. Female.Length 2.6–3.0 mm ( Fig. 28A). Color.Head and mesosoma dark iridescent blue. Pedicel pale brown. Femora mostly brown, tips pale. Head( Fig. 28B). HW:HH = 1.1–1.2; face rugose-reticulate; IOD: EH = 1.7–1.9; MS:EH = 0.9–1.0; malar depression weakly impressed adjacent to mouth; supraclypeal area as long as broad, weakly rugose-reticulate; anteclypeus distinct, broadly rounded. FL:HH = 1.3–1.4; F2L:F2W = 2.1–2.8, F2L:F3L = 1.1–1.3; following funiculars subequal in length, gradually broader; clava subovate ( Fig. 28D). Me-sosoma( Fig. 28C, G, H). ML:MH = 1.2–1.3. Axilla dorsally well above mesoscutellum; scutoscutellar sulcus narrowly separated from transscutal articulation; frenal line irregularly foveate; axillular sulcus weak and foveate. Upper mesepimeron smooth; lower mesepimeron nearly smooth with weak carinae. Metepisternum weakly rugose-areolate. HCL:HCW = 1.6–2.1, costate; HFL:HFW = 6.6–8.9. FWL:FWW = 2.5–2.7, FWL:ML = 2.3–2.5; basal area sparsely setose, speculum bare, costal cell and wing disc setose; submarginal vein with several long setae; stigmal vein slightly angled toward wing base. Metasoma.PTL:PTW = 5.4–6.5, PTL:HCL = 2.1–2.4, lateral margin rounded. Apical setae of hypopygium with one pair of long setae. Ovipositor with subapical carina present; first (ventral) valvula with 6–8 small, narrowly separated teeth, second (dorsal) valvula with 6 or 7 annuli that are broadly separated dorsally by smooth area ( Fig. 28F).
