Length 2.2 mm, body slender, head and thorax dark green, with metallic reflection, gaster dark brown (Fig. 6 A); eyes and ocelli dark red, mandible yellowish-brown; antennal flagellum light yellow, scape dark green with metallic reflection, pedicel dark brown; coxae concolor with body, legs yellow except basal part of femurs dark brown; forewing hyaline, venation albescent. Head in frontal view 1.3 × as wide as high (Fig. 6 B), covered with rough reticulate, clypeal margin straight, clypeus with longitudinal striation. Antennal insertion on lower ocular line, distance from upper margin of torulus to lower margin of anterior ocellus 1.6 × distance from lower margin of torulus to lower margin of clypeus. Antennal scape not reaching vertex, two discoid anelli, F 1 shortest and square, clava 2.55 × as long as wide, and with tubercles at apical, length of flagellum and pedicel combined longer than head width (0.86 ×). Head in lateral view, malar sulcus slender not distinct, eyes height 1.62 × malar space. Head in dorsal view (Fig. 6 C), 2.45 × as wide as height, POL 1.84 × OOL. Mesosoma flattened (Fig. 6 D), pronotum without carina, significantly narrower than the mesoscutum, mesoscutum 1.22 × as wide as long, notauli incomplete, scutulum 1.32 × as wide as long, frenal line not distinct, propodeum with finer reticulate in the middle area, median carina and plica not distinct, nucha short. Forewing hyaline (Fig. 6 E) marginal vein 1.28 × postmarginal vein, postmarginal vein longer than stigmal vein (1.38 ×), basal cell bare, speculum small. Gaster sessile, flattened, 2.43 × as long as wide, slightly longer than the combined length of head and thorax, ovipositor does not protrude. Male. Length 1.7 ± 0.1 mm (Fig. 6 F), body slender, head and thorax dark blue, gaster dark brown, forewing hyaline, venation light brown, antennal pedicel dark brown, anellus light yellow, flagellum brown, each funicular segments with whorled light seta (Fig. 6 G). Hosts. Unknown. Etymology. ‘ flavus ’ means golden yellow, which is the distinctive color of its antennae. Diagnosis. The new species is similar to H. sinensis, but differs in having POL 1-1.11 × OOL, each funicular segment longer than broad, marginal vein 2.3 × stigmal vein, and mesosoma 2 × as long as broad.
