(Figs. 10 –18,29)  
 Etymology. The specific name is derived from the body being entirely black.   
 Holotype. female, CHINA: Weichang County, 41.98°N, 117.76°E, 842m, Hebei Province, 21 April 2014, Mao-Ling Sheng, Tao Li.   
 Paratypes. 1 male, same data as holotype except 18 April 2014; 1 female, 5 males, same data as holotype except 21 April 2014; 5 females, 6 males, same data as holotype except 23 April 2014; 1 female, 4 males, same data as holotype except 24 April 2014; 9 females, 9 males, same data as holotype except 25 April 2014; 5 females, 4 males, same data as holotype except 26 April 2014; 40 females, 36 males, same data as holotype except 27 April to 8 May 2014.   
 Diagnosis. Postocellar line 1.4–1.5x as long as ocular-ocellar line. Hind femur 5.0–5.2x as long as its widest width. First hind tarsomere approximately 10.0x as long as widest width. Tarsal claw comparatively small, basal portion with 2 o 3 teeth. Ovipositor sheath 1.5–1.6x as long as first tergite, 1.4–1.5x as long as hind femur, 1.2–1.3x length of hind tibia. Head, mesosoma, metasoma and hind legs entirely black.   
 Description. Female. Body length 6.2–6.5 mm. Fore wing length 4.0– 4.8 mm. Ovipositor sheath length 1.8– 2.0 mm.   
 FIGURES 10–18. (Continued) Head. Inner margins of eyes slightly convergent downwards, weakly concave near antennal sockets. Face (Fig. 11) coarsely coriaceous, with indistinct punctures, narrowest width approximately as long as total length of face and clypeus, upper median portion slightly convex. Clypeus gradually polished forwards apex, with sparse, distinct, fine punctures; median portion slightly convex. Mandibles comparatively short, basal portion finely granulated, apical polished, lower margin lightly elevated. Lower tooth of mandible almost as long as upper tooth. Cheek finely coriaceous. Malar space 0.5–0.6x as long as basal width of mandible. Gena finely coriaceous, with indistinct punctures, in lateral view approximately as long as widest width of eye. Vertex (Fig. 12) with texture as that of gena, subhind margin with weak transverse concavity. Interocellar area weakly convex. Postocellar line 1.4– 1.5x as long as ocular-ocellar line. Ocular-ocellar line 1.2–1.3x as long as diameter of postocellus. Frons with texture as that of face. Antenna with 30–31 flagellomeres; ratio of length from first to fifth flagellomeres approximately: 4.0:3.6:2.5:2.4:2.3. Occipital carina complete, lower end joining base of mandible.   
 Mesosoma. Lateral concavity of pronotum with weak transverse wrinkles, posterior portion coriaceous or finely granularly coriaceous. Epomia weak and short. Mesoscutum (Fig. 13) comparatively convex, finely coarse, without puncture. Notaulus indistinct. Scutoscutellar groove broad, with fine transverse wrinkles. Scutellum strongly convex, finely shagreened, with indistinct fine punctures. Postscutellum transversely convex, shagreened, anterior portion transversely concave. Mesopleuron (Fig. 14) and metapleuron densely finely granularly coriaceous. Upper anterior portion of mesopleuron between speculum and subalar prominence with dense oblique longitudinal wrinkles. Speculum almost smooth. Upper end of epicnemial carina reaching about 0.5 level of front margin of mesopleuron. Posterior transverse carina of mesosternum complete. Lower portion of metapleuron concave, lower-posterior portion with weak, indistinct oblique wrinkles. Submetapleural carina complete, strong. Wings slightly grayish, hyaline. Fore wing with vein 1cu-a slightly distal to 1/M, approximately by 0.5x width of vein. Areolet slanting quadrangular, shortly petiolate, receiving vein 2m-cu lightly basal of lower-posterior corner. Vein 2-Cu slightly longer than 2cu-a. Hind wing vein 1-cu evidently inclivous, cu-a almost absent; 2-Cu unpigment. Hind femur 5.0–5.2x as long as its widest width. Ratio of length of hind tarsomeres 1:2:3:4:5 is 10.0:4.2:3.1:1.9:2.8, first tarsomere approximately 10.0x as long as widest width. Tarsal claw comparatively small, basal portion with 2 to 3 teeth. Propodeum (Fig. 15) coarse, with complete, strong anterior transverse, median longitudinal, lateral longitunal and pleural carinae. Costula slightly arched downwards. Area basalis convergent backwardly, longer than widest width. Area superomedia combined with area petiolaris, combined area deeply, longitudinally concave, with indistinct transverse wrinkles. Propodeal spiracle oval, distance to pleural carina less than its longest diameter.   
 Metasoma. First tergite 3.0–3.1x as long as apical width, basal portion almost smooth, apical portion finely granularly coriaceous; dorsolateral carinae complete; suture (Fig. 16) separating from sternite at 0.3 the distance from base of the tergite lying at the mid-height of the segment. Second and subsequent tergites finely granularly coriaceous. Second tergite (Fig. 17) 1.32–1.43x as long as apical width. Ovipositor sheath 1.5–1.6x as long as first tergite, 1.4–1.5x as long as hind femur, 1.2–1.3x length of hind tibia. Ovipositor slightly curved upwardly, with distinct subapical dorsal notch.   
 Color (Fig. 10). Black, except the following: ventral profiles of front femora and front tibiae brown, front and mid tarsi and ventral profiles of mid tibiae brownish black, front profiles of mid femora blackish brown.   
 Male. Body length 4.0– 5.5 mm. Fore wing length 2.8–3.9 mm. Antenna with 27–31 flagellomeres. Areolet slanting quadrangular, petiole 0.6–0.9x as long as areolet.   
 Cocoon (Fig. 18). Length 7.0–9.0 mm. Grey. Cocooned in the cocoon of host.   
 Host. Epinotia rubiginosana rubiginosana (Herrich-Schäffer, 1851) (Lepidoptera, Tortricidae).   
 Host plant. Pinus tabulaeformis Carrière.   
 Remarks. This new species can be easily distinguished from any other species of genus Sinophorus Förster by the following characters: head, mesosoma, metasoma and hind legs entirely black.
