Chinese name: Ûūḧ瓢•
Diagnosis. This species is most similar to S. lancetapicalis (Pang & Gordon, 1986), but can be distinguished from the later by the apically expanded penis (Fig. 41e). In S. lancetapicalis, penis is not expanded at apex (Fig. 43e).
Description. TL: 1.64–2.23 mm, TW: 1.17–1.64 mm, TH: 0.64–0.92 mm.
Body oval, moderately convex, surfaces covered with short pubescence (Figs 41a–c). Head yellowish brown with interocular distance distinctly greater than eye width in frontal view. Pronotum yellowish brown. Scutellar shield brown to black. Elytra black with yellowish brown apices. Ventral surfaces yellowish brown to black. Legs yellowish brown. Abdominal postcoxal lines incomplete, slightly recurved toward the base of ventrite (Fig. 41d).
Male genitalia: Penis stout, penis capsule with stout outer arm and long inner one, apex of penis expanded with distinct membranous appendage (Figs 41e–f). Penis guide with prominent keel at base in lateral view, then tapering towards apex; parameres about 2/3 as long as penis guide, with a tuft of long setae at apex; penis guide in ventral view widest near the base, then gradually narrowing to apex (Figs 41g –h).
Female genitalia: Coxites elongate, triangular; styli well developed with terminal setae; spermatheca distinctly curved, with basal ramus and elongate nodulus.
