Description. Holotype: Ƥ. Length, 11 mm ( Figs 1 View FIGURE 1 a, 5a). Body metallic blue; postocellar area, temple and postorbit copper red, other parts of head with copper luster, palpi dirty brown; antenna blue, interior of apex of 5th antennomere and most of 6th to 9th antennomeres white except venter of 6th to 9th dark brown; anterior of fore femur, anterior of fore tibia and fore tarsus, base of middle tarsus, base of 4th tarsomere of hind leg dirty white. Forewing smoky gray with apex infuscated, cell C dark brown, hind wing hyaline, stigma and veins black. Hairs on dorsum of head dark brown, other body hairs pale brown.
Punctures on head coarse and dense; punctures on temple small and very sparse, with large shiny interspaces; punctures on postocellar area large, interspaces narrower than diameter of punctures ( Fig. 17 View FIGURE 17 a); mesoscutum with shiny interspaces between punctures, anterior slope sparsely punctured, shiny, posterior slope densely and coarsely punctured; punctures on upper half of mesepisternum dense and large, interspaces narrow, lower half sparsely punctured, interspaces shiny; mesepimeron microsculptured, shiny, upper margin densely punctured; upper half of metepisternum densely punctured, interspaces narrow, venter sparsely punctured; metepimeron densely microsculptured, punctures on dorsum dense and large, posterior shiny (Fig. 16d); all tergites with dense transverse microsculpture (16l).
Hairs on dorsum of head sparse, most as long as and few 1.5 × transverse diameter of median ocellus; hairs on dorsum of thorax straight, shorter than transverse diameter of median ocellus. Anterior margin of clypeus truncate; malar space equal to transverse diameter of median ocellus; lower interocular distance about 1.2 × eye height; anterior margin of supraantennal tubercle elevated, frontal ridge fine; middle fovea round and deep, lateral fovea deep; interocellar furrow and postocellar furrow wide and deep; postocellar area elevated, middle distinctly higher than top of ocelli, with middle carina, about 1.2 × as broad as long; lateral furrows deeper posteriorly, slightly curved outwards in middle, parallel posteriorly; head behind eyes 0.8 × eyes in length in dorsal view, convex at base and narrowing posteriorly. Antenna subequal to abdomen and about 1.2 × head and thorax combined in length. Mesoscutellum acutely pyramidally elevated, anterior slope flat, longer than posterior slope, without middle carina; mesepisternum without ventral spur. Apex of hind tibia distinctly enlarged; metabasitarsus 4 × as long as broad, 0.8 × length of remaining 4 tarsomeres combined; hind inner tibial spur 0.5 × length of metabasitarsus. Hind wing with petiole of anal cell equal to half length of cu-a. Ovipositor sheath nearly as long as middle tibia; lancet as in Fig. 9 View FIGURE 9 f; apical and 5th to 8th serrulae as in Fig. 11 View FIGURE 11 c.
Male: Length, 10 mm ( Figs 1 View FIGURE 1 b, 5b). Similar to female in structure and color, except color of forewing darker; dorsum of 6th to 8th antennomeres dirty white; punctures on temple moderate ( Fig. 17 View FIGURE 17 b); lower interocular distance 0.8 × eye height; malar space equal to transverse radius of median ocellus; hairs on dorsum of head curved, hairs on dorsum of thorax slightly curved, most equal to transverse diameter of median ocellus, hairs on mesoscutellum longer than transverse diameter of median ocellus; metapleuron as Fig. 16h; microsculpture on basal 2 abdominal tergites as Fig. 16p; subgenital plate as long as broad, apex round; genitalia as in Figs 14 View FIGURE 14 f, 15f.
Variation. The punctures on temple are very sparse in one male.
Etymology. The specific epithet is a noun and refers to the strongly microsculptured first abdominal tergite.
Specimens examined. Holotype: Ƥ, Deqin (28º29´N, 98º 54.5´E), Yunnan, alt. 3200 m, 15 July 2004, Xiao Wei leg., CSCSHT 0 0 810042 (CSCS). Paratypes: Yunnan: 13, Deqin (28º29´N, 98º 54.5´E), Yunnan, alt. 3200 m, 15 July 2004, Zhou Hu leg.; 13, Mt. Baimaxue (28º17.473´N, 99º 53.157´E), Deqin, Yunnan, alt. 3500 m, 16 July 2004, Zhou Hu leg..
Distribution. China (Yunnan).
Remarks. The new species is somewhat similar to S. szechuanica , but differs by the following: the first abdominal tergite densely microsculptured, mat; postocellar area strongly elevated, middle longitudinal carina obvious; lateral furrows parallel; mesoscuteullm with an acute peak; inner hind tibial spur 0.5 × basitarsus; metepimeron microsculptured. In S. szechuanica the first abdominal tergite is shiny without distinct microsculpture; postocellar area flat, middle longitudinal carina obscure; lateral furrows divergent; mesoscuteullm roundish; inner hind tibial spur 0.6 × basitarsus; most of metepimeron shiny.
