Description. Female. Body length (excluding ovipositor sheath) 6.8 mm, length of extended part of ovipositor 4.6 mm, fore wing length 4.6 mm.
Head. Antennomeres 32; length of third flagellomere 1.1×fourth flagellomere; length of third, fourth and penultimate flagellomeres 4.7, 4.2 and 1.4×their width, respectively. Frons crest-shaped and elevated and punctate latero-dorsally, rugose-punctate latero-ventrally, medially reticulate-punctate and with a long median protruding lamella. In dorsal view length of eye 1.3×temple (Fig. 3d). Malar suture absent (Fig. 3c). Length of malar space 2×basal width of mandible, 0.6×maximum width of eye (Fig. 3c). POL: OD: OOL=10: 6: 22 (Fig. 3c). Face 0.6×as high as wide and 1.5×as wide as eye height and 0.6×as wide as head (Fig. 3b). Face convex, densely punctate (Fig. 3b). Vertex and temple smooth and shiny with moderately long hairs, rugose near mandible (Figs. 3c, 3d). Clypeus rugose-punctate, distinctly separated from face by deep epistomal suture (Fig. 3b).
Mesosoma. Length almost 2×as long as its height (Fig. 3h). Pronope small, but distinct. Side of pronotum medially coarsely crenulate, postero-dorsally rugose-punctate, ventrally coarsely reticulate-punctate, remainder densely punctate (Fig. 3h). Mesoscutal lobes punctate (Fig. 3e). Notauli wide and deep, crenulate, posteriorly coarsely reticulate-punctate and with a medial carina (Fig. 3e). Scutellum smooth, laterally and posteriorly rugose-punctate (Fig. 3e). Precoxal sulcus wide and deep, coarsely crenulate, ventrally and posteriorly rugose-punctate (Fig. 3h). Scutellar sulcus rugose and with one median carina (Fig. 3e). Metanotum without a median carina. Propodeum coarsely rugose-reticulate and with a median longitudinal carina.
Wing. Fore wing about 3×as long as wide (Fig. 3g). 1-M almost straight (Fig. 3g). Stigma 2.5×as long as wide (Fig. 3g). r: 3-SR: SR1=11: 15: 67 (Fig. 3g). 2-SR: 3-SR: r-m=20: 15: 17 (Fig. 3g). 1-M: m-cu= 32: 19 (Fig. 3g). SR1 straight (Fig. 3g). 1-M almost straight (Fig. 3g). cu-a inclivous, postfurcal (Fig. 3g). 1-CU1 very short (Fig. 3g). r-m vertical (Fig. 3g). Hind wing, 1-M: 1r-m=18: 25. cu-a inclivous.
Legs. Length of fore tarsus almost equal to length of fore tibia. Length of femur, tibia and basitarsus of hind leg 3.4, 8.6 and 7.1×their width, respectively. Hind femur robust. Length of outer and inner hind tibia spur 0.22 and 0.27×basitarsus, respectively.
Metasoma. First tergite subparallel-sided, densely reticulate-punctate, dorsal carinae distinct in basal two-thirds (Fig. 3f); length of first tergite 1.2×its apical width (Fig. 3f). Second tergite reticulate-punctate anteriorly and medially, latero-posteriorly smooth (Fig. 3f). Third tergite punctate baso-medially, remainder smooth (Fig. 3f). Ovipositor sheath 2×as long as metasoma, 2.3×as long as hind tibia, 2.3×as long as mesosoma and 1.0×as long as fore wing.
Colour. Black. Palpi, fore and mid tibia, tarsi yellow brown, rest of legs dark brown. Antenna, tegula and pterostigma reddish brown. Veins brown. Wing membrane light brown. Ovipositor sheath dark brown.
Variation. Antennomeres 32–33. Body length (excluding ovipositor sheath) 6.8–9.0 mm, fore wing length 5.0– 6.3 mm. Precoxal sulcus wide and deep, coarsely rugose-crenulate medially, anteriorly and posteriorly crenulate.
Male. Unknown.
Diagnosis. Aspicolpus jilinensis sp. n. is similar to A. erythrogaster (Tobias, 1967), but differs in having the length of malar space 2×basal width of mandible (the latter 1.6×basal width of mandible); in dorsal view length of eye 1.3×temple (the latter 1.5×temple); scutellum smooth, laterally and posteriorly rugose-punctate (the latter sparsely punctate); second tergite reticulate-punctate anteriorly and medially, latero-posteriorly smooth (the latter smooth) and third tergite punctate baso-medially, remainder smooth (the latter smooth).
Distribution. China (Jilin).
Host. Unknown.
Etymology. It is named after the type locality of the species, Jilin Province, China.
