Diagnosis. This species is similar to S. hamatus (Yu & Pang, 1993), but can be distinguished from the later by its straight penis guide in lateral view ( Fig. 54g ). In S. hamatus , the penis guide is strongly curved upwardly in lateral view (Fig. 51g).

Description. TL: 1.60–2.21 mm, TW: 1.21–1.63 mm, TH: 0.73–0.99 mm.

Body oval, moderately convex, surfaces covered with short pubescence ( Figs 54a–c ). Head yellowish brown with interocular distance slightly greater than eye width in frontal view. Pronotum yellowish brown. Scutellar shield black. Elytra black with yellowish brown apices. Ventral surfaces yellowish brown to black. Legs yellowish brown. Abdominal postcoxal lines almost complete ( Fig. 54d ).

Male genitalia: Penis slender, penis capsule with long inner arm but without outer one, apex of penis pointed ( Figs 54e–f ). Penis guide widest at base in lateral view, gradually narrowing to blunt apex; parameres about 1/4 as long as penis guide, with a tuft of long setae at apex; penis guide widest at base in ventral view, tapering towards blunt apex ( Figs 54g –h ).

Female genitalia: Coxites shortened; styli absent; spermatheca worm-like, with basal ramus and nodulus.
