DESCRIPTION — FEMALE: Holotype (Figures 7-10). Body length. 3 mm. Color. Head and mesosoma black, without

metallic reflections. Metasoma dark brown. Eyes and ocelli pale red. Mandibles reddish-brown, darker basally. Antennae black. Legs with coxae concolorous with mesosoma; femora dark brown; tibiae dark brown, becoming yellowish-brown distally; tarsi yellowish-brown, last segment brown. Wings hyaline, venation dark brown (Figures 7-10). Head coriaceous except finely striate clypeal area and smooth scrobes. Alveolae inside ocellar triangle smaller than those on surrounding areas. Antenna (Figure 9) with scape not reaching lower margin of median ocellus; flagellum with fl1 and fl2 anelliform, without longitudinal sensilla, fl2 slightly wider than the first, followed by three large but transverse segments (fl3-fl5), each of them with one row of dense longitudinal sensilla; tips of sensilla slightly exceeding the length of segments; clava with the first two segments transverse, the last one conical. Relative measurements: head length: 26, width: 64, height: 50; POL: 12; OOL: 11; eye height: 29, length: 20; IOD: 39; eye length dorsally: 30; temple length dorsally: 4; malar space: 15; distance between clypeal margin and lower margin of toruli: 9; scape length: 26; pedicel length: 10, width: 5; pedicel plus flagellum: 50; fl3 length: 5.5, width: 9; fl4 length: 6, width: 10; fl5 length: 6, width: 10; clava length: 18, width: 10. Mesosoma mostly flattened dorsally (Figure 7). Pronotal collar smooth except finely coriaceous lateral sides; pronotal neck abrupt and finely coriaceous. Mesoscutum, axillae and scutellum finely coriaceous, except smooth axillulae; frenal area smoother than rest of scutellum. Dorsellum smooth (Figure 10). Propodeal median area mainly smooth, except finely wrinkled area around median carina; spiracular sulcus and callus mainly smooth, the later bare; posterior corners of median area, anterior to transverse carina and separating median area from adpetiolar margin, with one small pit each (Figure 10). Prepectus with shallow uniform reticulation. Mesepisternum reticulate; upper mesepimeron large and smooth, lower mesepimeron shallowly reticulate and separated from upper mesepimeron by groove. Metapleura shallowly reticulate. Hind coxa coarsely reticulate (Figure 10). Fore wing (Figures 7-8) with basal cell and basal fold bare; costal cell bare except a few setae in distal part; speculum large, reaching to S; a single row of admarginal setae present beyond M; stigma moderately large, uncus conspicuous; marginal fringe well developed. Relative measurements: mesosomal length: 90, width: 60, height: 35; mesoscutum length: 31; scutellum length: 30, width: 37; dorsellum length: 9; propodeum length: 19; fore wing length: 185, width: 80; M: 50; S: 10; P: 5. Metasoma longer than head plus mesosoma, elongate and widening distally (Figures 7-8). Dorsal surface smooth except finely coriaceous gt4-gt7. Posterior margin of gt3-gt5 medially incised. Hypopygium reaching tip of gaster. Ovipositor sheaths well protruding beyond tip of gaster (Figure 7). Relative measurements: petiole length: 20, width 9; gaster length (excluding ovipositor sheaths): 120, width: 33; gt1-gt3 combined length: 90; ovipositor sheaths length: 27.
