Diagnosis. This species is similar to S. bivalvis (Yu, 1997) in structures of the male genitalia, but can be distinguished from the later by elytra with two yellow C-shaped patterns, and parameres about 1/3 as long as penis guide (Figs 28a–b, 28g). In S. bivalvis, elytra are black with yellowish brown apices, parameres are about 1/2 as long as penis guide (Figs 39a–b, 39g).
Description. TL: 1.55–2.45 mm, TW: 1.07–1.83 mm, TH: 0.67–0.92 mm.
Body oval, moderately convex, surfaces covered with short pubescence (Figs 28a–c). Head yellowish brown with interocular distance distinctly greater than eye width in frontal view. Pronotum yellowish brown, sometimes with a black spot. Scutellar shield black. Elytra with two yellow C-shaped patterns as show in Figure 28a. Ventral surfaces yellow to black. Legs yellowish brown. Abdominal postcoxal lines incomplete, recurved toward the base of ventrite (Fig. 28d).
Male genitalia: Penis stout, penis capsule with stout outer arm and long inner one, apex of penis constricted with membranous appendage (Figs 28e–f). Penis guide with prominent keel at base in lateral view, then tapering towards pointed apex; parameres about 1/3 as long as penis guide, with a tuft of long setae at apex; penis guide approximately parallel sided for basal 1/ 3 in ventral view, apically pointed (Figs 28g –h).
Female genitalia: Coxites elongate, triangular; styli well developed with terminal setae; spermatheca distinctly curved, with basal ramus and elongate nodulus.
