Types. Holotype, Female, CHINA: Laoshan Forest Farm, 229m, Qingdao , Shandong Province, 12 May 2017, IT . Paratype: 1 female, Huangshagang Forest Farm, 450m, Wumeishan Natural Reserve , Xiushui , Jiangxi Province, 10 July 2016, IT.

Diagnosis. Face 1.6 to 1.7 × as wide as long. Median portion of pleural carina of propodeum present as thin edge. Second tergite 1.5 to 1.9 × as long as posterior width; thyridia comparatively deep, distance between it and anterior margin approximately half its length. Third tergite 1.5 to 2.0 × as long as its posterior width. All femora brownish red. Hypopygium reddish brown.

Description. Female. Body length 24.5 to 27.4 mm. Fore wing length 14.8 to 15.3 mm. Ovipositor sheath length 28.0 to 31.0 mm.

Head. Inner margins of eyes almost parallel. Face 1.6 to 1.7 × as wide as long, median portion distinctly convex, with even, dense punctures. Clypeal suture shallow, indistinct. Clypeus 2.0 to 2.1 × as wide as long, almost smooth, shiny, with sparse indistinct punctures, apical median portion strongly swelling (elevated) ( Fig. 2 View FIGURE 2 ). Main portion of mandible with sparse punctures; upper tooth slightly longer than lower tooth. Malar area granulated, with dense yellow brown hairs. Subocular sulcus indistinct. Malar space approximately 0.7 × as long as basal width of mandible. Gena (Fig. 3) almost shiny, with comparatively sparse, fine punctures; lower portion slightly shagreened. Vertex ( Fig. 4 View FIGURE 4 ) smooth, shiny, with uneven punctures. Postocellar line approximately as long as ocularocellar line. Frons almost flat, with dense punctures. Antenna with 35 to 38 flagellomeres. Ratio of length from first to fifth flagellomeres: 1.8:1.2:1.1:1.0:1.0.

Mesosoma. Pronotum ( Fig. 6 View FIGURE 6 ) with uneven, irregular punctures, upper-posterior portion slightly convex. Mesoscutum ( Fig. 5 View FIGURE 5 ) almost shiny, with dense punctures, distance between punctures 0.2 to 2.0 × diameter of puncture. Scutoscutellar groove shiny, with sparse fine punctures. Scutellum evenly convex, with dense punctures, posterolateral margin with dense yellowing brown hairs. Anterior portion of postscutellum smooth, with sparse punctures; posterior portion densely punctate. Mesopleuron ( Fig. 6 View FIGURE 6 ) slightly evenly convex, with dense punctures. Speculum transverse, smooth, shiny. Upper end of epicnemial carina reaching about 0.2 level of posterior margin of pronotum. Posteromedian portion of mesosternum ( Fig. 7 View FIGURE 7 ) deeply longitudinally concave. Metapleuron evenly convex, with dense punctures, distance between punctures 0.5–2.0 × diameter of puncture. Anterior portion of submetapleural carina strongly convex, as a broad lobe, somewhat translucent, with indistinct longitudinal wrinkles. Fore wing vein 1cu-a distal of 1/M, distance between them about 0.4 × as long as 1cu-a. Areolet obliquely quadrate, petiolate, receiving vein 2m-cu at apical 0.2 to 0.3. 2-Cu approximately 1.5 × as long as 2cu-a. Hind wing vein 1-cu about 1.5 × as long as cu-a. Claw pectinate ( Fig. 11). Ratio of length of hind tarsomere 1:2:3:4:5 is 7.7:3.5:2.0:1.0:1.4. Propodeum ( Fig. 8 View FIGURE 8 ) evenly convex, without carina except indistinct vestige of pleural carina; apical portion strongly narrow; median portion with comparative sparse punctures; subapicalmedian portion with dense indistinct irregular rugae. Propodeal spiracle elliptical.

Metasoma. First tergite ( Fig. 12 View FIGURE 12 ) 1.9 to 2.3 × as long as posterior width, with dense indistinct punctures; apical median portion smooth, shiny; median dorsal carina reaching about 0.6 to spiracle; spiracle circular, small, located at anterior 0.3 of first tergite. Second tergite ( Fig. 13 View FIGURE 13 ) approximately 0.9 × as long as first tergite, 1.5 to 1.9 × as long as its posterior width, with dense punctures, apical median portion smooth, shiny; thyridium comparatively deep, shiny, distance between it and anterior margin of second tergite approximately half its length. Third tergite 1.5 to 2.0 × as long as its posterior width, with dense punctures. Anterior portions of fifth and subsequent tergites almost shiny, apical portions with fine punctures. Hypopygium large, triangular, with apical median triangular emargination. Ovipositor sheath 4.3 to 4.7 × as long as hind tibia. Subapical portion of ventral valve of ovipositor ( Fig. 14 View FIGURE 14 ) with five distinct vertical teeth.

Coloration ( Fig. 1 View FIGURE 1 ). Black, except for the following. Face and main portion of mandible with yellowish brown hairs. Wings brownish hyaline. Maxillary and labial palpi yellowish brown. Inner orbits, basal portion of clypeus, mandible except teeth, lower-anterior and upper-posterior portions of pronotum, anterolateral longitudinal band of mesoscutum, anterolateral spots of scutellum, tegula, subalar ridge, lower-posterior portion of mesopleuron, fore and mid coxae and trochanters, dorsal profile of hind coxa and apical portion of trochanter yellow. Ventral profile of hind coxa brownish black. All femora brownish red. Fore and mid tibiae and tarsus yellowish brown. Hind tibia and tarsus brownish black. Pterostigma and veins brownish black. Hypopygium reddish brown.

Variation. Face entirely black, or with small sublateral longitudinal spots. Distribution. CHINA: Shangdong, Jiangxi.

Etymology. The name of the new species is based on the lower valve of the ovipositor with distinct teeth.
