( Figs. 1–8 View FIGURE 1 – 9 , 10 View FIGURE 10 – 17 , 18–22 View FIGURE 18 – 27 )
Diagnosis. This species is similar to S. (P.) tsugae in general appearance, but can be distinguished from it by the following characters: penis guide nearly parallel at 2/3 length, gradually converging apically to a pointed tip in ventral view; parameres distinctly shorter than penis guide, 2/3 length of the latter.
Description. TL: 2.12–2.36 mm, TW: 1.44–1.64 mm, TH: 1.00– 1.12 mm, TL/TW: 1.44–1.47, PL/PW: 0.51– 0.53, EL/EW: 1.21–1.22.
Body elongate oval, moderately convex, dorsum surface with fine, yellowish white pubescence ( Fig. 10 View FIGURE 10 – 17 ). Head, antennae and mouthparts yellowish white. Pronotum yellow. Scutellum and elytra reddish brown. Underside yellow except the mesoventrite and metaventrite reddish brown.
Head small, 0.58× of pronotal width (HW/PW=0.68/1.16). Punctures on head dense and evenly separated by 0.5–2 diameters, with silvery white pubescence. Eyes small and almost oval, rather coarsely faceted, the widest interocular distance about 0.53× of head width. Pronotum about 0.73× of elytral width (PW/EW=1.20/1.64), pronotal punctures fine, sparse, and slightly larger than those on head, 1–2 diameters apart. Surface of elytra with sparse puncture, separated by 1–3 diameters. Prosternal carinae nearly parallel, extending to anterior margin. Prosternal process rectangle, length 3 times of width at the base ( Fig. 7 View FIGURE 1 – 9 ). Abdominal postcoxal lines incomplete, slightly recurved toward the base of ventrite ( Figs. 6 View FIGURE 1 – 9 , 18 View FIGURE 18 – 27 ). Area surrounded by the line evenly punctured, narrowly smooth along the line.
Male genitalia: Penis slender, penis capsules are quite differently from the other species ( Fig. 19 View FIGURE 18 – 27 ). Apex of penis with thread-like appendage ( Fig. 20 View FIGURE 18 – 27 ). Tegmen moderately stout, penis guide nearly parallel at 2/3 length, converging gradually apically to a pointed tip in ventral view ( Fig. 22 View FIGURE 18 – 27 ). Parameres distinctly shorter than penis guide, 2/3 length of the latter, obliquely truncate on distal margin, with two groups of uniform setae inserted in different directions ( Fig. 21 View FIGURE 18 – 27 ).
Female genitalia: coxites triangular, elongated, about 2.70 times as long as width at the base, tapering to blunt apices, outer and inner margin almost straight, each with several long terminal setae. Spermatheca C-shape, sclerotised ( Fig. 8 View FIGURE 1 – 9 ).
