Description. Holotype: Ƥ. Length, 14 mm ( Figs 2 View FIGURE 2 f, 6b). Body metallic blue; labrum dark brown; dorsum of apex of 6th antennomere and dorsum of 7th to 8th antennomeres white; anterior of fore femur and of tibia, fore tarsi, most of middle tarsi, dorsum of hind 3rd tarsomere and 4th to 5th tarsomeres yellow brown. Wings infuscated, apical third smoky, cell C blackish; stigma and veins black. Hairs on dorsum of head dark brown, hairs on thorax pale.
Punctures on head dense and coarse, interspaces narrow, microsculptured ( Fig. 19 View FIGURE 19 a); thorax densely punctured, anterior of scutum shiny; anterior slope of mesoscutellum densely punctured, middle sparsely punctured, interspaces shiny; punctures on posterior slope and metascutellum large, interspaces narrow, mat; lateral margin of posttergite microsculptured, middle shiny, impunctate; mesepisternum densely and coarsely punctured, punctures on venter sparse and shallow, interspaces shiny; mesepimeron microsculptured, middle area shiny, upper margin densely and coarsely punctured, posterior margin shiny; middle and lateral of 1st abdominal tergite feebly punctured and microsculptured, other parts shiny, other tergites densely microsculptured and sparsely punctured.
Hairs on dorsum of head curved, 1.8 × transverse diameter of median ocellus. Anterior margin of clypeus truncate; malar space as long as median ocellus; lower interocular distance as long as eye height; anterior margin of supraantennal tubercle weakly elevated, posterior confluent with frontal ridge; middle fovea broad furrow like, lateral fovea deep; interocellar furrow broad and deep, postocellar furrow broad and shallow; anterior of postocellar area slightly elevated, lower than top of ocelli ( Fig. 19 View FIGURE 19 b), without middle carina, about 1.3 × as broad as long; lateral furrows deep, slightly curved outwards, parallel posteriorly; head behind eyes 0.8 × eyes in length in dorsal view, convex at base and narrowing posteriorly ( Fig 19 View FIGURE 19 a). Antenna subequal to head, thorax and first abdominal tergite combined in length. Mesoscutellum pyramidally elevated, but not very high ( Fig. 19 View FIGURE 19 c), anterior slope flat, longer than posterior slope; posterior slope with a distinct middle carina; posttergite with an obtuse middle carina. Apex of hind tibia distinctly enlarged; metabasitarsus 4 × 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 shorter than half length of cu-a. Ovipositor sheath 1.2 × length of middle tibia, apical sheath 1.2 × as long as basal sheath; Lancet as in Fig. 9 View FIGURE 9 i; apical and 5th to 8th serrulae as in Fig. 13 View FIGURE 13 g.
Male: Length, 10 mm ( Figs 2 View FIGURE 2 g, 6c). Hairs on dorsum of head curved, 2 × transverse diameter of median ocellus; anterior margin of clypeus roundly protruding; malar space linear; lower interocular distance 0.7 × eye height; postocellar area about 1.5 × as broad as long; head behind eyes 0.5 ×length of eyes in dorsal view; genitalia as in Figs 14 View FIGURE 14 g, 15g.
Etymology. The specific epithet is a noun and is named after the type locality.

Distribution. China (Hubei).
Remarks. The new species is somewhat similar to S. metallica , but differs from the latter by the following: the apical 2/3 of forewing distinctly infuscated; the hairs on dorsum of head curved, 2 × transverse diameter of median ocellus; postocellar area without middle carina; mesoscutellum with a peak; 4th and 5th hind tarsomeres yellowish white; punctures on metapleuron shallow and fine; the upper margin of supraantennal tubercle elevated; valvicep of penis valve oval. In S. metallica : the apical 2/3 of forewing indistinctly infuscated; the hairs on dorsum of head nearly straight, equal to transverse diameter of median ocellus; postocellar area with a distinct middle longitudinal carina; mesoscutellum without peak; hind tarsi entirely blue; punctures on metapleuron dense and coarse; the upper margin of supraantennal tubercle obtuse; valvicep of penis valve narrow. See above key for differences between this new species and other species of the group.
