(Fig. 25)
Diagnosis. Distinguished from other species in the sixaolae group by smoother sculpture on the mesoscutal midlobe. Distinguished from O. sixaolae and O. nebula by the petiole being shorter than the hind coxae. Distinguished from O. brachycephala by the antennal flagellomeres being as wide as long.
Description. Female. Length 1.4 mm (Fig. 25A). Color. Head and mesosoma brown with bluish iridescence. Mandible brown. Femora mostly brown, tips pale; tibiae pale brown. Head (Fig. 25B). Head in frontal view subtriangular; HW:HH = 1.2; face smooth; longitudinal groove between eye and torulus present; eyes sparsely setose, IOD:EH = 1.6; MS:EH = 0.6; malar depression absent; supraclypeal area slightly broader than long, smooth; clypeus smooth; epistomal sulcus distinct and sharply defined. Labrum with 4 digits. Mandibular formula not observed; palpal formula 3:2. Occiput with dorsal margin abrupt; temples present, rounded. Pedicel globose, as broad as F1. FL:HH = 1.2; anellus disc-shaped; F2L:F2W = 0.8, F2L:F3L = 0.8; following funiculars subequal in length, gradually broader; clava subconical (Fig. 25D). Mesosoma (Fig. 25C, E). ML:MH = 1.5. Mesoscutal midlobe weakly reticulate, nearly smooth, sparsely setose; lateral lobe smooth. Axilla smooth; scutoscutellar sulcus narrow, regularly foveate, broadly separated from transscutal articulation; mesoscutellar disc slightly longer than broad, smooth; frenal line regularly foveate; axillular sulcus distinct and foveate. Propodeal disc areolate, smooth laterally (Fig. 25F); callus with several short setae on dorsal margin. Propleuron smooth. Prepectus smooth. Mesepisternum smooth. HCL:HCW = 1.9; HFL:HFW = 6.3, sparsely setose. FWL:FWW = 2.7, FWL:ML = 2.5; basal third of wing bare, wing disc evenly setose; submarginal vein with 8 long setae dorsally; stigmal vein perpendicular to anterior wing margin; postmarginal vein same length as stigmal vein. Hind wing costal cell with a few setae. Metasoma. PTL: PTW = 2.3, PTL:HCL = 0.8, areolate, lateral margin with longitudinal carina continuous with basal flange, ventral sulcus not observed. Antecostal sulcus foveate; acrosternite posteriorly angulate; apical setae of hypopygium with one pair of long setae. Ovipositor with subapical carina weak; first (ventral) valvula with 10 or 11 small, closely spaced teeth, second (dorsal) valvula with 8–10 annuli that are broadly separated dorsally by smooth area.
