Paratypes.

3 females, 2 males. Harbin City, Maoershan Town: Jianlagou. 4-17.VIII. 2014, Cheng-De Li, Hai-Feng Bai, Chao Zhang, Zhi-Guang Wu (2 ♀ ♀, NEFU), MT; same data as holotype (2 ♂ ♂, NEFU); Laoyeling. 16-29.VIII. 2013, Cheng-De Li, Hai-Feng Bai (1 ♀, NEFU), MT.

Diagnosis.

Funicle (Fig. 2) with 2 mps at least on fl4-fl8 and 7 mps on clava; mesoscutum (Fig. 4) without median longitudinal groove; frenum (Figs 4, 5) entirely reticulate; propodeum (Fig. 5) with median areole abutting metascutellum; the median carina absent and replaced by the two carinae forming inner margin of dorsolateral areoles; plica without an anterior bifurcation; petiole 3.54 –4.05× as long as wide; ovipositor (Fig. 7) slightly exserted, about 0.9 × as long as gaster, and 0.86 –0.90× as long as metatibia.

Ooctonus huberi sp. n. runs to Ooctonus novickyi in Triapitsyn’s key ( 2010), and the differences are shown in the key above. The new species is also similar to Ooctonus lokomotiv . Both species have 1 mps sometimes on fl3 and 2 mps on fl4-fl8 and have reticulation on mesoscutum and frenum, but Ooctonus huberi sp. n. differs from the latter by having 7 mps on the clava (8 mps in Ooctonus lokomotiv ); petiole 3.54 –4.05× as long as wide (2.6 –3.3× in Ooctonus lokomotiv ); and ovipositor 0.86 –0.90× as long as metatibia (1.2 –1.4× in Ooctonus lokomotiv ).

Description. Female. Body length 1240-1380. Head and mesosoma dark brown, metasoma brown; scape and pedicel mostly yellow except dorsally dark brown; fl1 brown, remainder of funicle dark brown; petiole and legs yellow except apical tarsomere brown.

Head. Head (Fig. 1) width 396-406. Vertex without stemmaticum. Mid ocellus diameter 29-31. Vertex with conspicuous reticulate sculpture; face with faint, inconspicuous reticulate sculpture.

Antenna. Antenna (Fig. 2) with scape 4.61 –5.25× as long as wide, slightly longitudinally striate; pedicel slightly longer than fl1; funicle with 2 mps on fl4-fl8 and 7 mps on clava, and sometimes fl3 with 1 mps on one antenna. Clava 3.17 –3.31× as long as wide, slightly longer than fl6-fl8 together. Measurements (length/width): radicle 53, scape 199-204/ 38-43, pedicel 65-72/ 36-38, fl1 60-72/ 22-24, fl2 70-79/ 24-26, fl3 72-77/ 26-29, fl4 77-82/ 29-34, fl5 77-79/ 31-36, fl6 72-77/ 31-36, fl7 70-79/ 36-38, fl8 58-65/ 43-46, clava 221-240/ 70-74.

Mesosoma. Mesosoma (Fig. 3) with pronotum weakly sculptured. Mid lobe of mesoscutum (Fig. 4) with meshes raised; scutellar setae long, extending posterior to medially concave frenal line; frenum 0.69 –0.75× mesoscutellum length and entirely reticulate. Metanotum with metascutellum smooth. Propodeum (Fig. 5) smooth between carinae and its anterior margin with a stub slightly lateral to lateral margin of metascutellum; median areole abutting metascutellum; the median carina absent and replaced by the two carinae forming inner margin of dorsolateral areoles; plica almost straight, extending almost to anterior margin of propodeum just medial to stub, without an anterior bifurcation but with a slight curved thickening posterior to the stub.

Wings. Fore wing (Fig. 6) length 1415-1512, width 512-585, length/width 2.57-2.76, longest marginal setae 77-84, 0.13 –0.15× as long as greatest wing width. Marginal vein length 125-132. Hind wing (Fig. 6) length 1049-1122, width 67-70, length/width 16-17, longest marginal setae 122-125.

Metasoma. Petiole 3.54 –4.05× as long as wide, 1.35 –1.38× as long as metacoxa, shorter than metacoxa + metatrochantellus. Gaster (Fig. 7) with ovipositor length 455-485, slightly exserted, 0.89 –0.91× as long as gaster, and 0.86 –0.90× as long as metatibia (515-525).
