Description. Holotype: Ƥ. Length, 13 mm ( Figs 3 View FIGURE 3 f, 6e). Body metallic blue; labrum blackish brown; 6th to 8th antennomeres and basal half of 9th antennomere yellowish white; fore leg with apical half of femur anteriorly, anterior of tibia, inner tibial spur and base of basitarsus pale brown. Wings hyaline and slightly infuscated at apices, cell C brown except base and apex blackish brown, stigma and veins blackish brown; hairs on dorsum of head dark brown, hairs on dorsum of thorax dark brown except hairs on anterior margin pale, hairs on pleuron pale.
Clypeus, frons, postocellar area and postorbit densely punctured, inner orbit and most of temple sparsely punctured, with large shiny patch ( Fig. 19 View FIGURE 19 j); scutum densely punctured, interspaces narrow, mesoscutellum coarsely and densely punctured, posttergite microsculptured; upper half of mesepisternum densely punctured and microsculptured, without shiny interspaces, lower half with sparse and large punctures; mesepimeron densely microsculptured except upper margin coarsely and densely punctured; dorsum of metepisternum densely punctured and microsculptured, other parts shiny; middle and posterior of metepimeron shiny, dorsum of metepimeron coarsely and densely punctured; 1st abdominal tergite shiny, other tergites densely microsculptured.
Hairs on frons and postorbit straight, slightly longer than transverse diameter of median ocellus; hairs on postocellar area straight, equal to transverse diameter of median ocellus; hairs on mesepisternum curved, longer than transverse diameter of median ocellus; hairs on mesoscutellum shorter than transverse diameter of median ocellus. Anterior margin of clypeus truncate; malar space 1.2 × transverse diameter of median ocellus; head in front view with eyes converging below, lower interocular distance 1.3 × eye height; anterior margin of supraantennal tubercle elevated, posterior confluent with frontal ridge; middle fovea round and broad, lateral fovea deep; interocellar and postocellar furrows shallow; postocellar area flat, lower than top of ocelli ( Fig. 19 View FIGURE 19 k), without middle carina, about 1.7 × as broad as long; lateral furrows deep, slightly curved outwards, parallel posteriorly; head behind eyes equal to eyes in length in dorsal view, convex at base and narrowing posteriorly. Antenna subequal to abdomen and 1.2 × head and thorax combined in length. Mesoscutellum acutely pyramidally elevated ( Fig. 19 View FIGURE 19 l), anterior slope flat, longer than posterior slope; posttergite with an obtuse middle carina; metascutellum with a distinct middle carina; mesepisternum angularly elevated, ventral spur faint. Apex of hind tibia distinctly enlarged; metabasitarsus 4.4 × as long as broad, 0.8 × length of remaining 4 tarsomeres combined; hind inner tibial spur 0.4 × length of metabasitarsus. Hind wing with petiole of anal cell shorter than half length of cu-a. Ovipositor sheath 0.9 × length of middle tibia, apical sheath and basal sheath subequal in length; lancet as in Fig. 8 View FIGURE 8 a, apical and 4th to 6th serrulae as in Fig. 12 View FIGURE 12 a.
Male: Unknown.
Variation. No variation is found in the type specimens.
Etymology. The name is from the locality of holotype and is a noun.
Specimens examined. Holotype: Ƥ, 24k, Bomê, Tibet, 29°48.287´N, 95°41.914´E, alt. 3563 m, 21 June 2009, Wei Meicai leg., CSCSHT 0 0 810031 (CSCS). Paratypes: Tibet: 1Ƥ, 24k, Bomê, Tibet, 29°48.380´N, 95°41.956´E, alt. 3522 m, 21 June 2009, Li Zejian leg.; 1Ƥ, 24k, Cibagou, Zayü, Tibet, 28°53.816´N, 97°27.771´E, alt. 2697 m, 23 June 2009, Niu Gengyun leg.
Distribution. China (Tibet).
Remarks. The new species is similar to S. sinica , but differs from the latter by the following: postocellar area flat; upper half of the inner orbit shiny; anterior and posterior slopes of the mesoscutellum flat, anterior slope densely punctured; posttergite microsculptured; metascutellum with a sharp middle longitudinal carina; apex of the forewing weakly infuscated, cell C brown; ovipositor sheath shorter than middle tibia; apical sheath as long as basal sheath; lancet sclerotized with serrulae protruding.
On the road from Bomê to Mêdog, there are many places named by digits, like 24k, 52k, and 80k. These names reflect their position at different distances from the start of Bomê.
