Etymology. From the Latin word flavidus (yellowish), in reference to the yellowish body of females.

Description. FEMALE (habitus: Fig. 22 ). Length = 3.5–4.3 [4.1] mm. Head ( Figs 19–22 ) green with reddishviolaceous luster at least on frontovertex and usually similar ( Figs 19, 21 ) or more coppery luster within scrobal depression; in lateral view ( Fig. 20 ) comparatively highly convex but frontal surface evenly curved so broadest near middle, about 1.3× as high as long; in frontal view about 1.2× as wide as long; in dorsal view almost 1.5× as wide as high with interocular distance about 0.33× head width, without distinct ocellocular mark though sometimes with concave, sometimes differently colored, lunate depression along outer margin of posterior ocellus ( Fig. 21 ), and with OOL: POL: LOL: MPOD = 8: 17: 10: 11. Frontovertex with vertex and ocellar triangle reticulate-punctate to reticulate-rugulose ( Fig. 21 ) and with very small region between ocelli and reticulate-rugulose scrobal depression often more transversely reticulate-strigose, the latter region with a vertical sulcus below anterior ocellus to within obscurely differentiated dorsal limit of scrobal depression ( Fig. 19 ), and with comparatively long and dense but thin, hairlike white setae. Scrobal depression ( Fig. 19 ) deep ventrally and shallowed dorsally to near anterior ocellus, bell-shaped with lateral margin slightly incurved above torulus such that slender parascrobal region differentiated along inner orbit, and with depression subdivided near mid-height by transverse, sinuate depression differentiating reticulate-rugulose dorsal part of depression from interantennal prominence and shiny, finely coriaceous scrobes; interantennal prominence comparatively highly and narrowly convex and depressed dorsally so as to be somewhat Y-shaped between transverse depression above each scrobe ( Fig. 19 ). Interantennal prominence, lower face and parascrobal region with white, slender-lanceolate setae ( Fig. 19 ). Mandible ( Fig. 23 : insert) bidentate with acute ventroapical tooth and broad, slightly incurved dorsoapical margin. Labial and maxillary palps yellow ( Fig. 19 ). Antenna with scape, pedicel, basal four flagellomeres and usually fifth flagellomere basally, plus apical two clavomeres pale, yellowish compared to darker brown basal clavomere and at least apical three funiculars; length of flagellum + pedicel about 2.3× head width; scape slightly compressed and curved, similarly slender throughout; length[width] of scape: pedicel: funiculars: clava = 87[19]: 25[12]: 18[11], 41[13], 44[14], 59[18], 31[19], 26[20], 22[23]: 75[25].

Mesosoma ( Figs 24–26 ) mostly yellowish to light brownish-yellow except pronotum dark posterolaterally anterior to spiracle ( Fig. 24 ) and tegula apically and sometimes scutellum in part somewhat darker brown. Legs ( Fig. 22 ) similar in color to mesosoma with tarsi somewhat lighter than femora and tibiae. Pronotum in dorsal view ( Figs 21–24 ) with collar transverse-quadrangular, about 1.4× as wide as long with anterolateral corners rightangled relative to comparatively poorly differentiated anterior margin, the dorsal surface flat with anterior margin obtusely angled relative to neck on either side of deep mediolongitudinal furrow, and with sparse, inconspicuous pale setae. Mesoscutum ( Fig. 24 ) flat anteriorly and with lateral lobes carinately angled only within about posterior quarter or less; meshlike reticulate; with inconspicuous posteriorly directed setae similar in color to cuticle except posteromedially with at least a couple of more conspicuous, slightly lanceolate, posteriorly directed white setae on either side of midline near posterior margin. Scutellar-axillar complex ( Fig. 25 ) about 1.4× as long as basal width; axillae extending about half-length of scutellum, reticulate to obliquely reticulate-strigose, and with hairlike setae of similar color as cuticle along lateral margins; scutellum longitudinally reticulate to reticulate-strigose and with only one, much longer seta on either side near posterior limit of axilla, teardrop-shaped, about 2.2× as long as greatest width, with distinctly differentiated, shiny and only obscurely meshlike coriaceous frenal area. Tegula ( Figs 24, 26 ) with numerous dark setae, but not as differentiated setal tuft. Fore wing ( Fig. 25 ) extending to base of propodeum, about 2.8× as long as maximum width, flat, brownish-infuscate; costal cell not quite extending to, but vein complex extending to angulate apical margin of wing, with costal cell setose ventrally, vein complex dorsally setose with apical-most seta extending beyond apical margin of wing, and membrane behind venation transversely wrinkled and bare except for marginal setae in apical half. Mesopleurosternum ( Fig. 26 ) with mesopectus anterolaterally uniformly setose with ventrally projecting white lanceolate setae and acropleuron anteriorly with some anteriorly projecting white setae, but these not forming conspicuous, dense setal tuft; acropleuron meshlike reticulate to coriaceous-reticulate anteriorly to about posterior level of tegula, more reticulate-strigose along dorsal margin, meshlike-reticulate along posterior margin, and very finely meshlike coriaceous ventrally, but extensively smooth and shiny medially. Metacoxa ( Fig. 26 ) entirely setose with white setae over outer surface. Propodeum ( Fig. 25 ) comparatively long, almost as long medially as scutellum, with transverse posterior margin incurved at midline such that dorsally recurved contiguous margins form median carina extending to slightly incised anteromedial margin, the surface otherwise reticulate-rugulose and with a few similar, slender lanceolate white setae anterolaterally anterior to spiracle and posterolaterally near metacoxa.

Gaster ( Figs 22, 27 ) similarly colored as mesosoma except ventrally mostly pale, whitish ( Fig. 22 : insert); finely meshlike coriaceous and all but basal and apical tergites longitudinally wrinkled and with long setae similar in color to cuticle in more than one row across most tergites; syntergum ( Fig. 27 ) much shorter than penultimate tergite with syntergal flange differentiated as tapered, posteriorly rounded to angulate, bare region behind subapical row of brownish setae; ovipositor sheaths projecting distinctly beyond syntergum by distance about equal to 0.3× length of metatibia.

Distribution (Map 1B). Costa Rica.

Remarks. Females of O. flavida are differentiated by their unique body color pattern, which includes a distinctly bicolored flagellum ( Fig. 23 ) and a green head contrasting with a yellowish to light brownish-yellow mesosoma and gaster ( Fig. 22 ) except for a mostly whitish gastral venter ( Fig. 22 : insert). The scrobal depression is bell-shaped, quite deep ventrally and extending to near the anterior ocellus with the dorsal margin only indistinctly delimited, but more conspicuously transversely subdivided at about mid-height above the interantennal prominence and scrobes ( Fig. 19 ). Although there are white setae on the acropleuron anteriorly ( Fig. 26 ) and the mesoscutum posteromedially ( Fig. 24 ), the setae are relatively sparse and inconspicuous rather than forming dense setal tufts as in most other species.

Only the holotype of the three available females is uncontorted and with the fore wings clearly visible. The longitudinal vein apparently consists mostly of the submarginal vein, but because the vein extends to the wing margin apically and the costal cell does not, the apical-most portion likely consists of a remnant of the marginal/ stigmal/postmarginal veins. This region of the venation is also slightly sinuate rather than straight, supporting it as other than just the submarginal vein.
