- Aspicolpus frontirugatus Yan et Chen, sp. n. ( Fig. 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). In dorsal view length of eye 1.3×temple (Fig. 2d). Malar suture absent (Fig. 2c). Length of malar space 1.1×basal width of mandible, 0.5×maximum width of eye (Fig. 2c). POL: OD: OOL=12: 10: 31 (Fig. 2d). Vertex punctate, surroundings of stemmaticum rugose-reticulate (Fig. 2d). Temple densely punctate, densely reticulate near mandible (Fig. 2c). Face punctate, slightly elevated centrally, rugose-punctate near mandible (Fig. 2b). Tentorial pits distinct, distance between pits shorter than distance from pit to eye (Fig. 2b). Clypeus convex, almost straight ventrally, its surface coarsely and densely rugose-punctate (Fig. 2b). Mesosoma. Length 1.6×as long as its height (Fig. 2e). 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). Precoxal sulcus long, almost straight, strongly rugose crenulate (Fig. 2e). 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). 1-M almost straight (Fig. 2f). Stigma 3×as long as wide (Fig. 2f). r: 3-SR: SR1=13: 15: 75 (Fig. 2f). 2-SR: 3-SR: r-m=22: 15: 16 (Fig. 2f). 1-M: m-cu=33: 22 (Fig. 2f). SR1 straight (Fig. 2f). cu-a inclivous, postfurcal (Fig. 2f). 1-CU1 short. r-m subvertical (Fig. 2f). Hind wing, 1-M: 1r-m=31: 27 (Fig. 2g). cu-a inclivous (Fig. 2g). 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). Length of first tergite 1.1×its apical width (Fig. 2h). Second tergite punctate medio-basally, remainder smooth (Fig. 2h). 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.
