(Fig. 12)
Diagnosis. Distinguished from other members of the O. bakeri group by having a dark, almost black body coloration (Fig. 12A) and mesoscutum with lateral lobes dorsally smooth (Fig. 12F). It is most similar to O. texana but lacks a depression in the midlobe of the mesoscutum (Fig. 12F), lacks a medial carina on the propodeum (Fig. 12F), and has a smooth to imbricate upper mesepimeron (Fig. 12C).
Description. Female. Length 2.2–2.8 mm (Fig. 12A). Color. Head and mesosoma dark bluish-black. Scape dark brown with iridescence; pedicel and dark brown. Maxilla and labium brown. Tibiae light brown. Fore wing venation pale brown. Head (Fig. 12B). Head in frontal view subquadrate; HW:HH = 1.1–1.4; scrobal depression shallow, laterally rounded, with transverse striae; eyes sparsely setose, IOD:EH = 1.7–1.9; MS:EH = 0.7–0.9; supraclypeal area about as long as broad, shorter than clypeus, smooth; epistomal sulcus distinct and sharply defined; anteclypeus distinct, broadly rounded. Palpal formula 3:2. Occiput with dorsal margin evenly rounded. Pedicel small and globose. FL:HH = 1.0–1.1; F2L:F2W = 0.8–1.2, F2L:F3L = 1.0–1.2 (Fig. 12D). Mesosoma (Fig. 12C, F). ML:MH = 1.2–1.4. Mesoscutal midlobe bare; lateral lobe dorsally smooth; notauli deep. Axilla smooth to slightly reticulate, dorsally rounded, on roughly same plane as mesoscutellum; scutoscutellar sulcus narrow, irregularly foveate, narrowly separated from transscutal articulation; mesoscutellar disc as long as broad, reticulate; frenal line as smooth band, foveate posteriorly; axillular sulcus anteriorly absent, narrow and foveate posteriorly; axillula areolate-reticulate. Propodeal disc flat, without depression or carina (Fig. 12G); callus reticulate, bare; callar nib absent. Propleuron nearly flat. Postpectal carina weak. Upper mesepimeron smooth to imbricate; lower mesepimeron reticulate; transepimeral sulcus distinct. Metepisternum laterally reticulate. HCL:HCW = 1.4–1.9; HFL:HFW = 4.1–5.8, evenly covered with short, dense setae. FWL:FWW = 2.1–2.5, FWL:ML = 1.9–2.1; fore wing with basal third bare, wing disc setose; marginal fringe minute; submarginal vein with minute setae; marginal vein with minute setae; stigmal vein about twice as long as broad, slightly angled toward wing apex; postmarginal vein slightly longer than stigmal vein. Metasoma. Petiole broad, linear in profile, PTL:PTW = 0.6–1.3, PTL:HCL = 0.4–0.8, reticulate, lateral margin with longitudinal carina continuous with basal flange, ventral sulcus absent. Subapical carina absent; second (dorsal) valvula with 8–10 annuli that are narrowly separated dorsally, with carinae coalescing.
Male. Length 2.0– 2.4 mm. HW:HH = 1.2–1.3. FL:HH = 1.2–1.4, F2L:F2W = 1.0–1.2 (Fig. 12E). Tibiae light brown. PTL:PTW = 1.6–2.3, PTL:HCL = 0.8–1.3.
Hosts. Unknown.
Plant associates. Some specimens from Charlotte, North Carolina were collected from wild carrot (Daucus carota L.; Apiaceae), specimens from Bangs, Texas were collected from a peach orchard, and one other specimen from Texas was swept from Gaillardia (blanket flower; Asteraceae); none are associated with observing oviposition.
