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+CU 1 weakly curved, sclerotized; vein r-m present, slightly oblique; 1 -R 1 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 SR 1 slightly curved; m-cu antefurcal; cu-a postfurcal and inclivous; 1 -CU 1 slightly widened; CU 1 b short. Hind wing (Fig. 6): M+CU: 1 -M: 1 r-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+CU 1 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. Biology. Unknown.
