Lower face weakly strigose, clypeus bilobed, mandible tridentate, supraclypeal area slightly concave and extending to the toruli. Malar sulcus present, incomplete, reaching about ⅔ of malar space. Malar space glabrous, smooth. Genal carina present. Toruli positioned above the lower ocular line about 1/3 of the eye length, diameter of torulus 3.3 xthat of the intertorular space. Scrobal depression deeply excavated. Vertex areolate, anterior ocellus above scrobal depression, ratios of POL:OOL:LOL equal to 3:4:1. Ventral plaque on scape forming a projection on the inner face below the attachment point to the pedicle. Ratio of scape (minus radicle):pedicel:anellus:F1:F2:F3:F4:F5:F6:club as 10:2.7:1:5.7:6.3:6.3:5.7:5:4.7:6.7, pedicel chalice-shaped, funicular segments with multiple irregular rows of longitudinal sensilla whorls of setae, much shorter than its bearing segment, clava 2-segmented (Fig. 25). Postgenal lamina present.   Figure 22-23.  Kavayva davidsmithilateral habitus 22female 23male. Photos by Cecilia Escobar.   Wing.Forewing infumated half way down the wing below the submarginal and marginal vein, not exceeding stigmal vein. Ratio of marginal vein:postmarginal vein:stigmal vein as 2.3:1.2:1 (Fig. 27).   Mesosoma.Mesosoma umbilicate, 1.7 xas long as broad. Notauli complete, shallow (Fig. 26). Anterior pronotal carina interrupted. Femoral depression of mesopleuron weakly striate, mesepimeron smooth and shiny ventrally, bulging laterally (Fig. 22). Dorsellum carinae diverging. Propodeum in lateral view forming a 90° angle with mesosoma, broadly delimited by carinae forming a hexagon with raised lateral corners. Median furrow of propodeum concave and smooth, bordered laterally by irregular setose cells. All femora with distal lamella.   Metasoma.Metasoma medially compressed, smooth, Gt6-syntergum setose. Gaster S-shaped in lateral view, ovipositor angled at about 30° dorsad to horizontal axis (Fig. 22). Gt4 emarginate posteriorly in dorsal view.  Male.9.4 mm. Scrobal depression black, otherwise color and sculpture as described for female (Fig. 23). Antennomeres with multiple rows of erect setae and about 1.4 xas long as width of segment (Fig. 26). Gastral petiole length in dorsal view about 2.8 xas long as its greatest width, 1.7 xas long as the length to metacoxa, smooth (Fig. 23).   Figure 24-25.  Kavayva davidsmithi 24male dorsal habitus 25frontal view of head. Photos by Cecilia Escobar.  Variation. The coloration on the vertex and occiput can be confluent or disconnected.  Biology. Associated with seeds of  Guarea guidonia( Meliaceae).  Distribution. Manu National Park, Peru.  Etymology. Patronym honoring David Smith for his decades of devotion to Hymenopteraand improvement of the Smithsonian'sNational Insect Collection.   Figure 26-27.  Kavayva davidsmithi 26male head and antennae 27female forewing.
