Punctures on head dense and coarse without shiny interspaces, labrum sparsely punctured; prescutum, scutum, and anterior slope of mesoscutellum densely punctured, with narrow interspaces; lateral parts of mesoscutellum sparsely punctured, interspaces shiny; posterior slope of mesoscutellum densely punctured, without interspaces; posttergite shiny with microsculptured laterally; parapsides with large and sparse punctures and dense microsculpture; metascutellum with anterior slope shiny and posterior slop densely punctured; metapostnotum shiny with margins slightly microsculptured; middle and upper of mesepisternum densely and coarsely punctured, without shiny interspaces, venter with large and shiny interspaces between small and sparse punctures; anepimeron coarsely punctured, upper of katepimeron with large punctures, interspaces obviously longer than diameter of punctures, middle and lower of katepimeron microsculptured; upper of metepisternum with dense and small punctures, interspaces shiny, narrower than diameter of punctures, venter sparsely punctured, shiny; basin of metepimeron microsculptured, dorsum with large punctures and posterior corner shiny. First abdominal tergite microsculptured, shiny, lateral edges slightly punctured; other tergites obviously microsculptured, mat, lateral edges of both 3rd and 4th tergites, posterior of 4th tergite, and most of 5th to 8th tergites obviously punctured.
Hairs on dorsum of head straight, about as long as diameter of lateral ocelli. Clypeus shallowly emarginate ( Fig. 7 View FIGURE 7 r), middle of clypeus with a transverse carina ( Fig. 7 View FIGURE 7 o); malar space as long as transverse diameter of median ocellus; shortest distance between eyes below antennal sockets in front view 1.1 × eye height; middle fovea shallow and broad; interocellar furrow deep, postocellar furrow broad and shallow; postocellar area 1.2 × as broad as long, distinctly elevated and about as high as top of ocelli, with an obscure middle ridge; lateral furrows straight, parallel and gradually shallow posteriorly; head behind eyes nearly as long as eye in dorsal view; curved laterally and then convergent posteriorly; genal carina developed, complete ( Fig. 7 View FIGURE 7 a). Antenna as long as head, thorax and basal two abdominal tergites together, as long as vein C, 2nd antennomere 1.5 × as long as broad, relative length of 3rd to 4th antennomeres as 1.8, 5th to 8th antennomeres weakly compressed, inner and outer sides of 5th to 8th antennomeres with weak furrows, 7th antennomere 2.3 × as long as broad. Middle furrow of prescutum distinct; mesoscutellum distinctly elevated, obviously higher than scutum. Metabasitarsus 4.7 × as long as broad, nearly as long as following 4 tarsomeres combined and 1.4 × length of following 3 tarsomeres combined, hind inner tibial spur 0.45 × length of metabasitarsus. Pulvilli of hind tarsus small. Ovipositor sheath 1.1 × length of middle tibia in lateral view; exposed part of apical sheath about 2 × as long as broad, apical sheath 1.4 × as long as basal sheath, apical sheath narrow in dorsal view, exposed part 4 × length of cerci, lateral setae on both sides of sheath straight, forming an angle about 50 degrees. Lancet broadened before apex, with 18 serrulae ( Fig. 9 View FIGURE 9 e), middle serrulae each with 14–15 distal fine teeth ( Fig. 9 View FIGURE 9 r).
Male. Length, 10.5 mm ( Figs 1 View FIGURE 1 d, 4d). Body black; 2nd to 4th abdominal tergites, 2nd to 5th abdominal sternites, and most of 6th and 7th sternites yellowish brown; legs yellowish brown, each coxa, fore and middle trochanter, dorsum of base of fore femur, stripe on dorsum of middle femur, apical 0.2 and stripe on dorsum of hind femur, and apical 0.3 of hind tibia black; similar to female in structure, but malar space 0.6 × transverse diameter of median ocellus ( Fig. 7 View FIGURE 7 c); shortest distance between eyes below antennal sockets in front view 0.9 × eye height; head behind eyes 0.5 ×eyes in dorsal view, curved laterally and then distinctly convergent posteriorly; hairs on temple as long as diameter of lateral ocelli ( Fig. 7 View FIGURE 7 b); genitalia as in Figs 10 View FIGURE 10 o, 10p.
Variation. Females 10.5–12 mm, males 10.5–11.5mm.

Remarks. The new species is similar to S. listoni and S. parallela but differs from them in clypeus with an obtuse transverse ridge and a small apical incision; the posterior margin of pronotum, tegula, the middle trochanter, the hind femur, tibia and tarsus black (the posterior of pronotum at most very narrowly margined with brownish line); the abdominal tergites and sternites black, only second tergite with a small white spot near spiracle; the hind femur in male with black macula but at least basal 4/5 yellow brown in outer side. The new species differs from S. listoni also in the forewings hyaline; antenna slender and the antennomeres 5–7 not dilated; and the apex of mesoscutellum round. The new species differs from S. parallela also in the pterostigma black brown; the apex of apical sheath not acute in lateral view; the posttergite with a middle carina; the antennomeres 2–3 and posttergite without pale spot. See the remarks under S. atra for the difference between S. carinoclypea and S. atra .
