1 ♀ (IRSNB). French Guiana, Montagne de Kaw, Relais Patawa, v.2001.


Female. Body length 4.3-4.4 mm or 4.5-4.6 mm. Fore wing length 4.5-4.6 mm or 4.7-4.8 mm. Body color: meso- and metasoma entirely yellow-orange (with the exception of a very small black spot on axillar complex) ( Figs 52, 56, 58 View Figures 52–58 ). Scape color: partially dark brown to black. Flagellomeres color: with relatively extense yellow area (at least including F13-15, and usually apical half of F11 and basal half of F16) ( Figs 52-54 View Figures 52–58 ). Tegula and humeral complex color: both pale. Mesotibia color: entirely yellow. Metatibia color: entirely yellow ( Fig. 55 View Figures 52–58 ). Metatibia spurs color: yellow-orange. Metatarsus color: dark brown to black (except for anterior 0.7 or less of first metatarsomere). Fore wing color pattern: hyaline. Fore wing veins color: all veins dark brown ( Fig. 53 View Figures 52–58 ). Pterostigma color: entirely dark brown. Hypostomal carina: not raised ( Fig. 57 View Figures 52–58 ). Scutoscutellar sulcus: with 6 impressions ( Fig. 56 View Figures 52–58 ). Areolet height÷vein r length (fore wing): 0.2 ×. Hind wing subbasal cell: mostly with setae. Hind tarsal claws: with 1 or 2 teeth on anterior 0.3 of claw. Shape of mediotergite 1: distinctly narrowing posteriorly, width at posterior margin clearly less than width at anterior margin and median width ( Fig. 58 View Figures 52–58 ). Mediotergite 1 length÷width at posterior margin 4.6-5.0 ×. Mediotergite 2 width at posterior margin÷length: 3.6-4.0 ×. Ovipositor sheaths length: 0.5 × as long as metatibia.
