Diagnosis. This species is similar to S. quinquepunctatus (Weise, 1923) in the characters of male genitalia, but can be distinguished from the later by parameres slightly shorter than penis guide (Fig. 23g). In S. quinquepunctatus, parameres are about 3/4 as long as penis guide (Fig. 2n).

Description. TL: 1.76–2.44 mm, TW: 1.34–1.86 mm, TH: 0.79–1.08 mm.

Body oval, moderately convex, surfaces covered with short pubescence (Figs 23a–c). Head yellow with interocular distance distinctly greater than eye width in frontal view. Pronotum yellow. Scutellar shield black. Elytra yellowish brown with parenthesis-shaped black markings. Ventral surfaces yellow to black. Legs yellow. Abdominal postcoxal lines incomplete, slightly recurved toward the base of ventrite (Fig. 23d).

Male genitalia: Penis stout, penis capsule with stout outer arm and long inner one, apex of penis distinctly expanded with membranous appendage (Figs 23e–f). Penis guide with prominent keel at base in lateral view, then tapering towards pointed apex; parameres conspicuously inflated, slightly shorter than penis guide, with a tuft of long setae at apex; penis guide approximately parallel sided for basal 1/ 3 in ventral view, then gradually narrowing to apex (Figs 23g –h).

Female genitalia: Coxites elongate, triangular; styli well developed with terminal setae; spermatheca distinctly curved, with basal ramus and elongate nodulus.
