Redescription.
Female. Body length 1.8 mm; fore wing length 1.6 mm.
Head. Head 1.9 × wider than its medial length (dorsal view), 1.1 × wider than mesoscutum. Occiput weakly evenly concave. Head behind eyes distinctly roundly narrowed; transverse diameter of eye ~ 4.5 × larger than length of temple in dorsal view or ~ 2.0 × in lateral view. Ocelli arranged in triangle with base 1.2 × its sides. POL 1.4 × Od, 0.5 × OOL. Eye 1.7 × as high as broad. Malar space almost equal to basal width of mandible, 0.15 × height of eye. Face weakly convex, width of face ~ 1.2 × its median height. Tentorial pits small, distance between pits 1.4 × distance from pit to eye. Clypeus high and weakly convex, its width 2.5 × median height, 0.8 × width of face; its lower margin medially almost straight. Head strongly roundly narrowed below eyes (front view).
Antenna. Antenna 20 - segmented, thickened, weakly setiform, submedial and apical segments elongate. Scape 2.1 × longer than wide. First flagellar segment 3.7 × longer than its apical width, 1.6 × longer than second segment. Tenth segment elongate, 1.6 × longer than wide.
Mesosoma. Mesosoma 1.4 × longer than maximum height. Mesoscutum highly and curvedly elevated above pronotum (lateral view), 1.7 × as wide as its medial length (dorsal view). Prescutellar depression (scutellar sulcus) short and shallow, with numerous distinct carinae. Scutellum 0.8 × as long as anterior width. Prepectal carina present laterally and absent ventrally. Precoxal sulcus distinct, long, oblique, sinuate, extending below almost throughout all mesopleuron, crenulate-rugose.
Wings. Fore wing damaged and distinctly dented anteriorly, ~ 3.0 × longer than maximum width. Radial vein (r) arising almost from distal 0.3 of pterostigma and far from first radiomedial vein (2 - SR). Present only single abscissa of radial vein (r), this vein distinctly curved, mainly desclerotised and reaching as track distal margin of wing. Radial (marginal) cell shortened. Metacarp (1 - R 1) sclerotised at basal part, its sclerotised part ~ 0.6 × as long as pterostigma. First radiomedial vein (2 - SR) distinctly sclerotised, ~ 6.0 × longer than recurrent vein (m-cu). Recurrent vein (m-cu) very weakly antefurcal to first radiomedial vein (2 - SR), posteriorly weakly divergent with basal vein (1 - M). Discoidal (discal) cell broadly sessile anteriorly, 1.4 × longer than its maximum width. Nervulus (cu-a) perpendicular to longitudinal anal vein (1-1 A), postfurcal, distance between basal vein (1 - M) and nervulus (cu-a) 0.5 × nervulus (cu-a) length. Hind wing ~ 3.0 × longer than maximum width. First abscissa of mediocubital vein (M + CU) ~ 2.7 × longer than second abscissa (1 - M).
Legs. Legs entirely missing.
Metasoma. Metasoma 1.1 × longer than mesosoma. First to third tergites sclerotised, with distinct, relatively wide, sparsely crenulate and weakly curved first and second sutures; following tergites relatively weakly sclerotised. Medial length of first tergite 0.6 × its apical width, approximately as long as second tergite. Second tergite almost 2.0 × longer than short third tergite. Length of first to third tergites combined 1.15 × their maximum width. Third tergite weakly curved in posterior margin. Ovipositor sheath narrow and short, ~ 0.25 × as long as first – third tergites combined.
Sculpture. Vertex densely and small areolate-punctate; frons areolate-punctate, but almost smooth medially; face transverse striate with reticulation between striae, only rugulose-reticulate medially, clypeus rather weakly and sparsely punctate, smooth between punctures. Mesoscutum densely punctate, with dense striation in medio-posterior one – third; scutellum rather densely and distinctly punctate, smooth between punctures. Mesopleuron smooth in long posterior area, mainly punctate with reticulation in anterior lower two – thirds; metapleuron mainly smooth, reticulate-areolate marginally. Propodeum mainly widely smooth, with areas distinctly delineated by high carinae, with wide and inversely-pentagonal areola (wide anteriorly and narrow posteriorly), anterolateral areas subsquare, posterolateral areas transverse-curved. First and second tergites entirely and sparsely striate, with dense rugosity between striae. Third and following tergites smooth.
Colour. Body mainly pale reddish brown, mesosoma reddish brown. Antenna yellowish brown. Palpi pale yellow. Fore coxa pale brown. Fore wing entirely faintly infuscate, without dark band under pterostigma. Pterostigma and parastigma brown; most veins brown.
Male. Unknown.
Distribution.
China (Zhejiang).
