Diagnosis.

Kavayva bodoquenensis can be distinguished from K. davidsmithi by the lack of black bands across mesosoma in dorsal view (Fig. 18 ), and the lack of ventral plaque in females.

Description.

Holotype female. 6.5 mm in length.

Color. Yellow except malar sulcus, supraclypeal area, Gt3-syntergum of the metasoma (except for pairs of yellow patches dorsad of Gt4 and Gt5), proximal half of femora and tibiae, wing veins, wing bands near basal setal line and marginal vein brown, edge of mandible, setae on head and mesosoma black and eyes pinkish red (Fig. 7 ).

Head. Quadrate with rounded corners, 1.2 × as wide as high in frontal view, 2.5 × as wide as long in dorsal view, areolate-rugose with setae (Fig. 11 ). Lower face weakly strigose, clypeus bilobed, mandible tridentate, supraclypeal area smooth, extending to the toruli. Malar sulcus present, incomplete, reaching to ⅔ of malar space. Malar space glabrous, smooth. Genal carina present, smooth. Toruli positioned above lower ocular line about 1/3 of the eye length, diameter of torulus 3.3 × that of the intertorular space. Scrobal depression deeply excavated, converging ventrally in frontal view (Fig. 9 ). Vertex areolate-umbilicate, anterior ocellus above scrobal depression, ratios of POL:OOL:LOL 4:5:1. Scape without ventral plaque. Ratio of scape (minus radicle):pedicel:anellus:F1:F2:F3:F4:F5:F6:club as 14:3.3:1:6:6:6:5.3:4:7, pedicel chalice-shaped, funicular segments cylindrical with multiple irregular rows of longitudinal sensilla whorls of setae, much shorter than its bearing segment, clava 2-segmented. Occiput concave, postgenal groove diverging, postgenal lamina present, subforaminal bridge ornamentation faint and inconspicuous (Fig. 10 ).

Wing. Forewing infumated below marginal and stigmal vein, band narrow, curving slightly proximally, and extending half way down the wing. Basal and costal setal line also infumated. Ratio of marginal vein:postmarginal vein:stigmal vein as 1.5:1 (Fig. 7 ).

Mesosoma. Mesosoma umbilicate, 1.2 × as long as broad. Notauli complete, shallow (Fig. 18 ). Anterior pronotal carina widely interrupted. Femoral depression of mesopleuron weakly striate, mesepisternum smooth (Fig. 14 ). Dorsellum carinae diverging. Propodeum in lateral view forming a 90° angle with mesosoma, concave and smooth medially, bordered laterally by irregular, ridged, setose cells (Fig. 15 ). All femora with distal lamella.

Metasoma. Metasoma medially compressed, smooth, Gt4-syntergum setose. Petiole very short and not visible while specimen is intact (Fig. 7 ). Gaster S-shaped in lateral view, ovipositor angled at about 30° dorsad to horizontal axis. Gt4 not emarginate posteriorly in dorsal view.

Male. 6.5 mm. Scrobal depression black, ventral half of body whitish-yellow, wing vein amber, otherwise color and sculpture as described for females. Ventral plaque on scape forming a projection on the inner face below the attachment point to the pedicle (Figs 12 , 13 ). Antennomeres with multiple rows of erect setae. Gastral petiole striate dorsally, 1.5 × as long as the length to metacoxa, smooth laterally (Fig. 17 ).

Variation. Size ranges from 3.5-6.5 mm. Color ranges from mostly yellow to mostly black dorsally, mesepisternum can range from smooth to weakly striate.

Larva. Head amber-colored and body beige. Body length 4.7 mm; width 1.7 mm. Body C-shaped; 13 segmented (three thoracic, nine abdominal, and one anal segments); tapering slightly posteriorly; no protuberance on body segments (Fig. 19 ). Head heavily sclerotized; antennae positioned ventrolaterally on the head, above the mandible, 1.29 × as long as broad. Two pairs of superior frontal setae near the cranial depression, two pairs of interior frontal setae around anterior tentorial pits, two pairs of clypeal setae, antennae low and offset laterally, two pairs of genal setae, two pairs of labral setae, and four pairs of hypostomal setae (Fig. 20 ). Mandible narrowing apically, bidentate, with two pairs of sensilla. Underlip complex flat, with two pairs of setae on the median lobe (labium), and one on the lateral lobe (maxilla) (Fig. 21 ). Thoracic segments with two dorsal setae, one pair of pleural setae, one pair of lateral setae, and one pair of ventral setae. Abdominal segments with a single pair dorsal, pleural, and ventral setae. Anal segment with one pair of dorsal terminal setae, and ventral terminal setae present.

Biology.

Associated with seeds of Guarea kunthiana and G. guarea = G. guidonia ( Meliaceae ).

Distribution.

Brazil, Panama.

Etymology.

Named in honor of the Serra da Bodoquena National Park, an environmental conservation unit in Mato Grosso do Sul, Brazil.

Remarks.

The specimens collected from Panama are slightly smaller (3.5-5.5 mm) than those from Brazil (5.5-6.5 mm), and with lighter coloration on the wings and metasoma which could be the result of specimens being older (Fig. 18 ). We did not find any consistent morphological differences in either sex that reliably separate the Panama specimens from those collected in Brazil. Therefore we chose to group them all within K. bodoquenensis until fresh material can be collected for molecular work.
