Diagnosis.

Female. Body length 1.1–1.7 mm, strongly sclerotized, mainly black to dark brown; antenna with scape yellowish brown to brown, pedicel and flagellum dark brown; fore wing hyaline. Head (Fig. 9 A, B ) with face and vertex smooth, frontal sulcus V-shaped, antennal scrobes meeting below meeting below frontal sulcus and connected frontal sulcus with longitudinal suture; clypeus trapezoid, 1.5 × as wide as high. Antenna (Fig. 9 C ) with five flagellomeres separated from each other; scape slightly stout, 5.2 × as long as wide; pedicel 1.5 × as long as wide; F 1 1.0 × as long and 2.0 × as wide as F 2; F 1 –5 with verticillate setae at base, the setae reaching or reaching beyond the apex of flagellomere attached to. Mesosoma (Fig. 9 D, E ) with mesoscutum and scutellum with distinct and sparse reticulation, meshes of reticulation mainly hexagonal; midlobe of mesoscutum with two pairs of setae and an incomplete shallow median groove; notauli as distinct deep grooves in posterior 1 / 2; scutellum 1.2 × as long as wide, with an incomplete median groove in anterior 1 / 2–2 / 3; metascutellum tongue like and without foveae anterolaterally; propodeum smooth, with a weak and narrow median carina, plica, between median carina and spiracular sulcus with a longitudinal carina, posterior part forming a short nucha; Fore wing (Fig. 9 J ) speculum closed, with 8–12 admarginal setae arising from MV and membrane just below MV; PMV shorter than STV, 0.7–0.8 × as long as STV, radial cell nearly bare (at least without setae along PMV). Metasoma (Fig. 9 I ), petiole quadratic to transverse, with anterior part drawn out to form a sharp margin that covers propodeal nucha; gaster 1.3 × as long as mesosoma, slightly longer than head + mesosoma (1.1: 1.0).
