Flores (1 ♀, CNC). Diagnosis . Propodeum without a median carina so the pentagonal areole is almost in contact with the dorsellum ( Figs 13, 14 ). Females of O. costaricensis are most similar to those of O . vulgatus Haliday and O . notatus from America North of Mexico . They differ from O . vulgatus by the absence of claval bullae (a row of several bullae in O . vulgatus ) and entirely reticulate frenum (medially smooth frenum in O . vulgatus ), and from O . notatus by the lack of mps on fl5 (two mps on fl 5 in O . notatus ). Description. Female. Body length 845–973 Μm (critical point dried, n=5). Head except mouthparts and mesosoma almost black; metasoma mostly yellow or light brown, sometimes with ovipositor and surrounding area brown or apical half dorsally brown; procoxa and mouthparts brown; antenna dark brown except scape and pedicel laterally and ventrally yellow; petiole and legs except procoxa and apical tarsomere, yellow with brown on much of femora dorsally and laterally. Fore wing ( Fig. 19 ) with distinct brown suffusion in basal half, especially along posterior margin. Head . Width (n=2) 262–306. Vertex without stemmaticum ( Figs 3, 4 ). Mid ocellus diameter 23– 27. Antenna . Measurements (length/width, n=2): scape 189–207/34–43, pedicel 68–74/36–37, fl1 56–67/17, fl2 46– 64/18–19, fl3 50–56/20–22, fl4 40–52/21–22, fl5 48–60/22–23, fl6 44–45/24–25, fl7 53–65/30, fl8 49–57/32–34, clava 162–188/59. Flagellum (Figs 8, 9) total length 385–476; with 2 mps on fl7 and fl8; fl1 slightly the longest funicle segment; fl1–fl6 length/width ratios (n=2): fl1 3.31–4.00, fl2 2.64–3.38, fl3 2.43–2.56, fl4 1.92–2.43, fl5 2.13– 2.57, fl6 1.85–2.23; clava 2.75–3.19× as long as wide, slightly longer than fl6–fl8 together, with 7 mps and without bullae (Fig. 8, inset). Mesosoma . Pronotum ( Figs 13, 14 ) with collar moderately short, with well defined transverse carina. Mesonotum midlobe with engraved meshes; scutellar seta moderately long, not quite extending posteriorly to medially straight frenal line; axilla reticulate, lateral panel of axilla and axillula smooth; frenum entirely reticulate. Metanotum with dorsellum smooth and lateral lobes with at most 1 longitudinal carina ( Figs 13, 14 ). Propodeum ( Fig. 14 ) slightly rugose between carinae; anterior margin with propodeal stub distinctly lateral to lateral margin of dorsellum; median areole almost abutting dorsellum, separated only by carina almost as wide as FIGURES 7–11 .
