Description. Female. Body length (excluding ovipositor sheath) 6.5 mm, length of extended part of ovipositor 3.7 mm, fore wing length 5.4 mm.
Head. Antennomeres 25; length of third flagellomere 1.2×fourth flagellomere; length of third, fourth and penultimate flagellomeres 4.8, 3.3 and 1.1×their width, respectively. Maxillary palp, palpomeres 6; length of maxillary palp 0.6×height of head. Labial palp 4-segmented. Frons with a crest-shaped elevation and punctate latero-dorsally, rugose-punctate latero-ventrally, medially rugose-reticulate and with a long median protruding lamella. In dorsal view length of eye 1.4×temple ( Fig. 4d View FIGURE 4 ). Malar suture absent ( Fig. 4c View FIGURE 4 ). Length of malar space 1.7×basal width of mandible, 0.7×maximum width of eye ( Fig. 4c View FIGURE 4 ). POL: OD: OOL=13: 8: 33 ( Fig. 4d View FIGURE 4 ). Face 0.5×as high as wide and 1.5×as wide as eye height and 0.6×as wide as head ( Fig. 4b View FIGURE 4 ). Face weakly convex, coarsely reticulate-punctate ( Fig. 4b View FIGURE 4 ). Vertex sparsely punctate ( Fig. 4d View FIGURE 4 ). Temple densely punctate dorsally, coarsely rugose-reticulate ventrally ( Fig. 4c View FIGURE 4 ). Clypeus coarsely and densely punctate, with a broad central thickening and concave medially, its apical margin convex ( Fig. 4b View FIGURE 4 ).
Mesosoma. Length almost 2×as long as its height ( Fig. 4e View FIGURE 4 ). Pronope shallow and wide, triangle-shaped. Side of pronotum medially crenulate, posteriorly and ventrally rugose-punctate, dorsally densely punctate. Mesoscutal lobes punctate, rugose-punctate posteriorly ( Fig. 4f View FIGURE 4 ). Notauli narrow and crenulate, with a medial carina posteriorly ( Fig. 4f View FIGURE 4 ). Scutellum punctate, coarsely rugose-punctate posteriorly and laterally ( Fig. 4f View FIGURE 4 ). Scutellar sulcus with one carina and several lateral crenulae ( Fig. 4f View FIGURE 4 ). Prepectal carina distinct ( Fig. 4e View FIGURE 4 ). Precoxal sulcus wide, coarsely crenulate ( Fig. 4e View FIGURE 4 ). Metanotum with a short median carina ( Fig. 4f View FIGURE 4 ). Propodeum coarsely rugose-reticulate and with a median longitudinal carina ( Fig. 4f View FIGURE 4 ).
Wing. Fore wing about 3×as long as wide ( Fig. 4g View FIGURE 4 ). 1-M posteriorly slightly curved ( Fig. 4g View FIGURE 4 ). Stigma 3.3×as long as wide ( Fig. 4g View FIGURE 4 ). r: 3-SR: SR1=15: 17: 81 ( Fig. 4g View FIGURE 4 ). 2-SR: 3-SR: r-m=25: 18: 20 ( Fig. 4g View FIGURE 4 ). 1-M: m-cu=38: 23 ( Fig. 4g View FIGURE 4 ). SR1 almost straight ( Fig. 4g View FIGURE 4 ). cu-a inclivous, postfurcal ( Fig. 4g View FIGURE 4 ). 1-CU1 short ( Fig. 4g View FIGURE 4 ). r-m vertical. Hind wing, 1-M: 1r-m =14: 16, cu-a inclivous.
Legs. Length of fore tarsus 1.2×fore tibia. Length of femur, tibia and basitarsus of hind leg 3.1, 8.2 and 5.8×their width, respectively. Hind femur robust. Length of outer and inner hind tibia spur 0.24 and 0.27×basitarsus, respectively.
Metasoma. First tergite parallel-sided, coarsely striate, dorsal carinae distinct and complete ( Fig. 4h View FIGURE 4 ); length of first tergite 1.1×its apical width ( Fig. 4h View FIGURE 4 ). Second tergite striated basally, remainder smooth ( Fig. 4h View FIGURE 4 ). Third tergite and following tergites smooth. Ovipositor sheath 1.6×as long as metasoma, 1.4×as long as hind tibia, 1.3×as long as mesosoma and 0.7×as long as fore wing.
Colour. Black. Palpi light yellow. Fore and mid tibiae, tarsi yellow. Fore and mid coxae, trochanters, femora, hind legs and ovipositor sheath yellow brown. Antenna and pterostigma reddish brown. Tegula dark brown. Wing membrane light brown and veins brown.
Variation. Antennomeres 24–26. Body length (excluding ovipositor sheath) 5.2–7.4 mm, fore wing length 4.2–5.8 mm. In one specimen second tergite nearly smooth.
Male. Unknown.
Diagnosis. Aspicolpus striatus sp. n. is similar to A. rugosus Chou et Hsu, 1998 , but differs in having the length of malar space 1.7×basal width of mandible (the latter 1.0×basal width of mandible); temple densely punctate dorsally, coarsely rugose-reticulate ventrally (the latter rugose-reticulate) and vertex sparsely punctate (the latter rather densely punctate).
Distribution. China (Fujian).
Host. Unknown.
Etymology. It is named after its coarsely striated first tergite.
