Description. Holotype: Ƥ. Length, 8.5 mm ( Figs 3 View FIGURE 3 i, 7c). Body metallic blue, labrum dark brown; basal half of left 6th antennomere white dorsally, 7th to 9th left antennomeres and 6th to 9th right antennomeres lost; most of anterior of fore femur, anterior of fore tibia, and entire fore tarsus pale brown; most of middle tarsus dark brown. Wings infuscated hyaline, apices weak smoky, cell C dark brown.Hairs on dorsum of head brown; hairs on thorax pale.
Punctures on head dense, temple sparsely punctured, interspaces shiny, wider than diameter of punctures; interspaces of punctures on postocellar area and postorbit narrower than diameter of punctures ( Fig. 21 View FIGURE 21 j); punctures on thorax dense, posterior of prescutum and middle of scutum sparsely punctured, shiny; anterior slope of mesoscutellum sparsely punctured, interspaces shiny, lateral and posterior slope densely punctured, mat; metascutellum densely punctured, interspaces narrow, posttergite shiny without punctures; punctures on upper half of mesepisternum dense and large, punctures on venter sparse; mesepimeron microsculptured, upper margin with large punctures; metepisternum shiny; punctures on dorsum of metepimeron large, posterior shiny; 1st abdominal tergite shiny except lateral sides feebly microsculptured, other tergites microsculptured.
Body short, forewing 1.3 × body length; hairs on dorsum of head curved, 2 × transverse diameter of median ocellus. Anterior margin of clypeus truncate; malar space 0.8 × transverse diameter of median ocellus; lower interocular distance equal to eye height; anterior margin of supraantennal tubercle elevated, posterior confluent with frontal ridge; middle fovea broad furrow like, lateral fovea deep; interocellar furrow broad and deep, postocellar furrow shallow and deep; postocellar area slightly elevated, lower than top of ocelli ( Fig. 21 View FIGURE 21 k), without middle carina, about 1.3 × as broad as long; lateral furrows straight, deep and broad, parallel posteriorly; head behind eyes 0.6 × eyes in length in dorsal view, convex at base and narrowing posteriorly. Mesoscutellum roundly elevated ( Fig. 21 View FIGURE 21 l), anterior slope longer than posterior slope, without middle carina; ventral thorn absent. Apex of hind tibia distinctly enlarged; metabasitarsus 4.6 × as long as broad, 0.9 × length of remaining 4 tarsomeres combined; hind inner tibial spur 0.5 × length of metabasitarsus. Hind wing with petiole of anal cell equal to 0.3 × cu-a in length. Ovipositor sheath as long as length of middle tibia; lancet as in Fig. 9 View FIGURE 9 a; apical and 6th to 8th serrulae as in Fig. 13 View FIGURE 13 d.
Male: Unknown.
Etymology. The specific epithet refers to the long wings comparing with the shortened body.
Specimens examined. Holotype: Ƥ, Jieyindian, Mt. Emei, Sichuan, 29°52.42´N, 103°34.03´E, alt. 2045 m, 11 June 2007, Liu Fei leg., CSCSHT 0 0 810038 (CSCS).
Distribution. China (Sichuan).
Remarks. The new species is similar to S. sinica , but differs from the latter by the following: body with metallic blue luster, without green luster; wings 1.3 × body length; mesoscutellum roundly elevated; malar space shorter than transverse diameter of median ocellus; the apices of wings feebly infuscated. In S. sinica : body with metallic bluish green luster; wings as long as body; mesoscutellum strongly elevated with a peak; malar space equal to transverse diameter of median ocellus; the apices of wings distinctly infuscated.
