Material examined. Holotype: 1♂, China, Zhejiang Prov., Linan, Tianmu Mountain, 11.VI.1993, Ling Teng, No. 935306 (ZJUH).
Description. Male. Body length 6.2 mm, fore wing length 5.8 mm.
Head. Antennomeres 38; length of third flagellomere 1.1×fourth flagellomere; length of third, fourth and penultimate flagellomeres 3.3, 3 and 2×their width, respectively. Maxillary palp, palpomeres 5; length of maxillary palp 1.4×height of head. Labial palp 3-segmented. Frons smooth dorsally, punctate ventrally, medially striate-punctate (Fig. 1d). In dorsal view length of eye 1.2×temple (Fig. 1b). Malar suture absent (Fig. 1c). Length of malar space 1.1×basal width of mandible, 0.4×maximum width of eye (Fig. 1c). POL: OD: OOL=9: 8: 20. Face 0.4×as high as wide and 1.4×as wide as eye height and 0.6×as wide as head (Fig. 1b). Face densely punctate (Fig. 1b). Vertex and temple sparsely punctate (Figs. 1c, 1d). Clypeus convex, coarsely rugose-punctate dorsally, ventrally striate and concave apical-medially (Fig. 1b).
Mesosoma. Length almost 2×as long as its height (Fig. 1h). Pronope deep and wide. Side of pronotum posteromedially crenulate, dorsally punctate, remainder nearly smooth. Mesoscutal lobes punctate (Fig. 1f). Notauli narrow and deep, crenulate, posteriorly coarsely reticulate-punctate and with a short medial carina (Fig. 1f). Scutellum smooth, weakly convex (Fig. 1f). Prepectal carina distinct (Fig. 1h). Precoxal sulcus crenulate-punctate, anteriorly punctate (Fig. 1h). Scutellar sulcus with one carina and several lateral crenulae (Fig. 1f). Metanotum with a complete median carina. Propodeum coarsely rugose-punctate and with a median longitudinal carina dorsally.
Wing. Fore wing about 3×as long as wide (Fig. 1g). 1-M almost straight (Fig. 1g). Stigma 3.5×as long as wide (Fig. 1g). r: 3-SR: SR1=12: 20: 77 (Fig. 1g). 2-SR: 3-SR: r-m=22: 20: 18 (Fig. 1g). 1-M: m-cu= 40: 24 (Fig. 1g). SR1 straight (Fig. 1g). cu-a inclivous, postfurcal (Fig. 1g). 1-CU1 very short (Fig. 1g). r-m vertical (Fig. 1g). Hind wing, 1-M: 1r-m=16: 16. cu-a inclivous.
Legs. Length of fore tarsus 1.1×fore tibia. Length of femur, tibia and basitarsus of hind leg 4.6, 9.3 and 6.7×their width, respectively. Length of outer and inner hind tibia spur 0.28 and 0.28×basitarsus, respectively.
Metasoma. First tergite rugose-punctate, widened posteriorly, dorsal carinae distinct in basal four-fifths (Fig. 1e); length of first tergite 1.3×its apical width (Fig. 1e). Second tergite rugose medially, remainder smooth (Fig. 1e). Third tergite and following tergites smooth.
Colour. Black. Most of mandible reddish yellow. Palpi, tarsi and apical one third of hind tibia whitish yellow (remainder dark brown). Coxae, trochanters, femora, fore and mid tibiae yellow. First tergite yellow. Tegula and wing membrane yellow brown. Pterostigma and most veins brown.
Female. Unknown.
Diagnosis. Aspicolpus clypeconcavus sp. n. is similar to A. punctus Chou et Hsu, 1998, but differs in having the frons smooth dorsally, punctate ventrally, medially crenulate-punctate (the latter punctate latero-dorsally, rugosereticulate medially and latero-ventrally); in dorsal view length of eye 1.2×temple (the latter 1.7×temple); length of first tergite 1.3×its apical width (the latter 1.6×its apical width) and second tergite rugose medially, remainder smooth (the latter smooth).
Distribution. China (Zhejiang).
Host. Unknown.
Etymology. From “ clype ” (Latin for “clypeus”) and “ concavus ” (Latin for “concave”), because of its clypeus concave apical-medially.
