Type material. Holotype, ♀ (RMNH), “N. Vietnam, Hoa Binh, Pa Co Hang Kia N.R., N20˚44'36", E104˚56'21", 1039 m, 23.x.2009, Taiw[an] tr[ap] 4, C. van Achterberg & R. de Vries, RMNH’09”. Paratype: ♀ (NWUX), “SW. China: Yunnan, Menglun, Xishuangbanna, c 540 m, 4.x.2010, Bot[anical] garden, 21˚93'N, 101˚26'E, Jiangli Tan, NWUX ”.
Description. Holotype, ♀, length of body 5.2 mm, of fore wing 4.7 mm (Fig. 1).
Head. Width 1.8× its median length in dorsal view, punctate dorsally and posteriorly. Behind ocellar triangle (stemmaticum) with a distinct pit; OOL: diameter of ocellus: POL= 7:5:4 (Fig. 3). Frons depressed, anterior half behind antennal sockets crenulate and laterally with some rugae; posterior half shiny and punctate medially and slightly rugose laterally (Fig. 3). Face densely setose, upper part transversely rugose; lower part densely punctate and laterally rugose except sparsely punctate medial part (Fig. 2). Clypeus weakly convex, coarsely punctate and its ventral margin thin and slightly concave; width of clypeus 2.2× its maximum height and 0.7× width of face; hypoclypeal depression distinct and narrow (Fig. 2). Antennal sockets strongly protruding (Fig. 3). Eye glabrous, in dorsal view 3.3× longer than temple, distinctly depressed along posterior and dorsal margins of eye (= subocular depression); eye slightly emarginated near base of antennal socket, 2.4× as high as broad in anterior view (Figs 2-4). Temple behind eye (in dorsal view) roundly contracted (Fig. 3). Occipital carina strongly developed and lamelliform laterally with a small angulate part dorsally (Fig. 3), largely absent medio-dorsally and separated from hypostomal carina ventrally (Fig. 4). Temple and malar space coarsely punctate; length of malar space 0.3× height of eye and 0.7× basal width of mandible; malar suture mainly developed near eye (Fig. 4). Mandible somewhat twisted and gradually widened baso-ventrally, with distinct teeth and ventral carina (Fig. 5); length of maxillary palp 1.3× height of head; labial palp segments slender. Antenna with 48 articles and 1.4× as long as fore wing; third article as long as fourth article, length of third, fourth and penultimate articles 1.6×, 2.0× and 4.5× their width, respectively.
Mesosoma. Distinctly flattened in lateral view; length of mesosoma twice its height (Fig. 7). Pronotum smooth laterally (but anteriorly with a distinct crenulate groove), crenulate posteriorly and finely punctate dorsally; dorsal pronope round and medium-sized (Figs 3, 8); propleuron evenly convex, shiny and punctulate (Fig. 7). Mesoscutum directly raised above pronotum, shiny and finely punctate; notauli incomplete, only impressed in anterior third of mesoscutum, rather deep and crenulate; medio-posterior depression of mesoscutum absent; transverse suture of mesoscutum present; scutellar sulcus deep and broad medially, with five carinae, 0.3 × as long as scutellum, laterally curved, narrowed and finely crenulate (Fig. 8); scutellum largely smooth, punctulate, flat, without subposterior depression; side of scutellum crenulate (Figs 7-8). Mesopleuron sparsely punctate; prepectal and postpectal carinae absent; precoxal sulcus wide, crenulate and sloping down; pleural sulcus smooth; mesepimeral flange widened near pleural scrobe (Fig. 7); mesosternal sulcus narrow and crenulate. Metapleuron medially punctulate and laterally coarsely crenulate or rugose (Fig. 7). Propodeum coarsely foveolate-reticulate with two small smooth patches antero-dorsally; transverse subbasal carina absent; median carina developed anteriorly and merged posteriorly into surrounding sculpture (Fig. 9).
Wings. Fore wing (Fig. 6): length 3.0× as long as its maximum width. Pterostigma elongate triangular, 3.6× as long as its maximum width; vein M+CU1 weakly curved, sclerotized; vein r-m present, slightly oblique; 1-R1 ending before wing apex; 2-SR:3-SR:r-m = 27:50:17; vein r slightly widened, arising before middle of pterostigma; 1-M and SR1 slightly curved; m-cu antefurcal; cu-a postfurcal and inclivous; 1-CU1 slightly widened; CU1b short. Hind wing (Fig. 6): M+CU:1-M:1r-m = 18:32:17; cu-a straight; m-cu absent.
Legs. Hind femur, tibia and basitarsus 3.4×, 8.6× and 5.8× as long as wide, respectively; hind tibial spurs about 0.2× hind basitarsus; hind tibia distally with six spines on its outer side (Fig. 10) and baso-laterally without oblique carina on its inner side.
Metasoma. Metasoma 1.2× as long as head and mesosoma combined; seven tergites exposed (Fig. 1). Tergite I 1.1× as long as wide apically, its surface moderately convex and coarsely rugose; dorsal carinae merged basally into a complete median carina (Fig. 9); laterope and glymma present (Fig. 11), dorsope absent. Second suture present; tergite II strongly rugose except smooth medio-posterior patch; tergite III shiny, sparsely setose with some longitudinal striae dorso-anteriorly and posteriorly with longitudinal impressions (Fig. 9); following tergites shiny and smooth but each apical margin superficially similarly impressed; tergites III–IV latero-posteriorly protruding (Fig. 11). Setose part of ovipositor sheath 0.2× as long as fore wing, 1.6× tergite I and 0.8× as long as hind tibia; hypopygium subtrunctate ventro-apically and about 0.7× as long as tergite I (Fig. 11).
Colour. Black or dark brown; head and mesosoma (except propodeum) brownish yellow; antenna, stemmaticum, tip of mandible, pterostigma, veins (but basal half of vein M+CU1 pale brown), hind tibia, hind tarsus (but telotarsus yellowish brown) and ovipositor sheath dark brown; palpi, fore and middle legs and hind coxa and hind femur, and metasoma ventrally pale yellow or yellowish white; wing membrane subhyaline (Fig. 1).
Variation. Length of body 5.2-6.8 mm, of fore wing 4.7-5.0 mm; antenna with 48 or 54 articles; length of mesosoma 1.9-2.0× its height; length of hind femur, tibia and basitarsus 3.4–4.0×, 8.6–10.0× and 5.8–7.0× as long as wide; length of first tergite 1.1–1.2× its apical width.
Distribution. Oriental China (Yunnan), NW Vietnam.
