( Fig. 2 View FIGURE 2 )

Material examined. Holotype: 1♂, China, Tibet Prov., Zhaxing, Gujing , 3500m, 22.IV.1973, No. IOZ(E)1689933 ( IZAS).

Description. Male. Body length 7 mm, fore wing length 6.5 mm.

Head. Antennomeres 39 (one antenna missing). Length of third flagellomere 1.3×fourth flagellomere; length of third, fourth and penultimate flagellomeres 4.3, 3.3 and 2×their width, respectively. Maxillary palp, palpomeres 5; length of maxillary palp 1.1×height of head. Labial palp 3-segmented. Frons densely rugose-reticulate, medioventrally with a longitudinal carina ( Fig. 2d View FIGURE 2 ). In dorsal view length of eye 1.3×temple ( Fig. 2d View FIGURE 2 ). Malar suture absent ( Fig. 2c View FIGURE 2 ). Length of malar space 1.1×basal width of mandible, 0.5×maximum width of eye ( Fig. 2c View FIGURE 2 ). POL: OD: OOL=12: 10: 31 ( Fig. 2d View FIGURE 2 ). Vertex punctate, surroundings of stemmaticum rugose-reticulate ( Fig. 2d View FIGURE 2 ). Temple densely punctate, densely reticulate near mandible ( Fig. 2c View FIGURE 2 ). Face punctate, slightly elevated centrally, rugose-punctate near mandible ( Fig. 2b View FIGURE 2 ). Tentorial pits distinct, distance between pits shorter than distance from pit to eye ( Fig. 2b View FIGURE 2 ). Clypeus convex, almost straight ventrally, its surface coarsely and densely rugose-punctate ( Fig. 2b View FIGURE 2 ).

Mesosoma. Length 1.6×as long as its height ( Fig. 2e View FIGURE 2 ). Pronope wide. Side of pronotum coarsely rugose-reticulate. Mesoscutal lobes punctate. Notauli narrow and deep, crenulate. Scutellum convex, densely punctate and finely rugose-punctate laterally. Prepectal carina distinct ( Fig. 2e View FIGURE 2 ). Precoxal sulcus long, almost straight, strongly rugose crenulate ( Fig. 2e View FIGURE 2 ). Scutellar sulcus with one carina and some lateral crenulae. Metanotum without a median carina. Propodeum densely punctate basally, remainder coarsely rugose and with a median longitudinal carina.

Wings. Fore wing 3×as long as wide ( Fig. 2f View FIGURE 2 ). 1-M almost straight ( Fig. 2f View FIGURE 2 ). Stigma 3×as long as wide ( Fig. 2f View FIGURE 2 ). r: 3-SR: SR1=13: 15: 75 ( Fig. 2f View FIGURE 2 ). 2-SR: 3-SR: r-m=22: 15: 16 ( Fig. 2f View FIGURE 2 ). 1-M: m-cu=33: 22 ( Fig. 2f View FIGURE 2 ). SR1 straight ( Fig. 2f View FIGURE 2 ). cu-a inclivous, postfurcal ( Fig. 2f View FIGURE 2 ). 1-CU1 short. r-m subvertical ( Fig. 2f View FIGURE 2 ). Hind wing, 1-M: 1r-m=31: 27 ( Fig. 2g View FIGURE 2 ). cu-a inclivous ( Fig. 2g View FIGURE 2 ).

Legs. Length of fore tarsus almost equal to length of fore tibia. Length of femur, tibia and basitarsus of hind leg 5, 9.6 and 6×their width, respectively. Length of outer and inner hind tibia spur 0.25 and 0.29×basitarsus, respectively.

Metasoma. First tergite widened posteriorly, rugose-reticulate, dorsal carinae distinct in basal half ( Fig. 2h View FIGURE 2 ). Length of first tergite 1.1×its apical width ( Fig. 2h View FIGURE 2 ). Second tergite punctate medio-basally, remainder smooth ( Fig. 2h View FIGURE 2 ). Third tergite and following tergites smooth.

Colour. Black. Palpi yellow. Mandible reddish brown largely. Tegula, fore and mid legs (except mid and hind tarsi yellow), hind coxa, trochanters and femur yellow brown. Hind tibia blackish yellow in basal two-fifths, remainder black. Pterostigma brown. Wing membrane faintly fumose with brown veins.

Female. Unknown.

Diagnosis. Aspicolpus frontirugatus sp. n. is similar to A. erythrogaster (Tobias, 1967) , but differs in having the length of malar space 1.1×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) and scutellum convex, densely punctate and finely rugose-punctate laterally (the latter sparsely punctate).

Distribution. China (Tibet).

Host. Unknown.

Etymology. From “ front ” (Latin for “frons”), and “ rugatus ” (Latin for “rugose”), because of its frons densely rugose-reticulate.
