( Figures 2F View Figure 2 , 5F–J View Figure 5 , 6)
Diagnosis
This species is similar to S. bicolor in general appearance and male genitalia, but based on Kamiya’s detailed descriptions and illustrations, it can be distinguished from the latter by the elytra with a red brown area ( Figure 2F View Figure 2 ). In S. bicolor , elytron is uniformly black. Their male genitalia are also distinctly diagnostic ( Figures 5F–J View Figure 5 ).
Description
TL: 1.02 mm, TW: 0.78 mm, TH: 0.47 mm, TL / TW: 1.30; PL / PW: 0.52; EL / EW: 0.90.
Head yellow, with eyes black. Pronotum yellowish brown. Ground colour of elytra yellowish brown, with sutural area reddish brown ( Figure 2F View Figure 2 ). Underside yellowish brown, except mesoventrite and metaventrite dark brown. Legs yellow.
Body minute, short oval, distinctly convex; dorsum pubescent. Head small, 0.47 times elytral width (HW / EW = 1: 2.14); frons convex, with fine punctures, separated by 1.5–3.0 times their diameter, with short and sparse hairs; eyes small and coarsely faceted, widest interocular distance 0.66 times width of head. Pronotum 0.77 times elytral width (PW / EW = 1: 1.30), pronotal punctures fine, similar to those on head, separated by 2.0–4.0 times their diameter. Punctures on elytra large, separated by 0.5–1.5 times their diameter. Surface of proventrite and mesoventrite slightly shagreened, with several setae. Punctures on metaventrite moderately large, separated by 1.0–3.0 times their diameter, with short and dense setae in punctures. Abdominal postcoxal line incomplete, reaching lateral margin smoothly, divided into two lines, with associated small pits and pores ( Figure 5F View Figure 5 ).
Male genitalia. Penis simple and slender, curved and narrowing toward apex; penis capsule indistinct ( Figure 5G,H View Figure 5 ); penis guide in lateral view slender and almost straight, almost subparallel at basal five-sixths, somewhat bulging at apical one-sixth, apex pointed and strongly bent; parameres short and indistinct, with several setae ( Figure 5I View Figure 5 ); penis guide in ventral view stout and straight, narrowed at base, tapering apical, apex pointed and slightly bent ( Figure 5J View Figure 5 ).
