( Figures 47–49 View FIGURES 47 – 55. 47 – 49 , 178–182 View FIGURES 178 – 186. 178 – 182 , 298 View FIGURE 298 )

Diagnosis. This species is similar to S. formosana in dorsal color pattern, but can be distinguished from latter as follows: anterior spots on elytra touching anterior elytral margins ( Fig. 47 View FIGURES 47 – 55. 47 – 49 ), penis very long and slender ( Fig. 179 View FIGURES 178 – 186. 178 – 182 ), and penis guide slightly shorter than parameres ( Fig. 180 View FIGURES 178 – 186. 178 – 182 ). In S. formosana , anterior spots on elytra do not touch anterior elytral margins ( Fig. 33 View FIGURES 29 – 37. 29 – 31 ), penis is short ( Fig. 155 View FIGURES 150 – 158. 150 – 153 ), and penis guide is longer than parameres ( Fig. 156 View FIGURES 150 – 158. 150 – 153 ).

Description. TL: 2.70–2.90 mm, TW: 2.51–2.67 mm, TH: 1.38–1.48 mm, TL/TW: 1.08–1.09; PL/PW: 0.43– 0.45; EL/EW: 0.83–0.89; HW/TW: 0.23; PW/TW: 0.63.

Head reddish brown, mouthparts yellow. Pronotum and scutellum black. Elytra black, each elytron with 2 large yellowish spots, anterior spot very large, irregular, at middle of basal margin (touching margin), posterior small, 1/ 2 size of anterior spot, at apical third ( Figs 47–49 View FIGURES 47 – 55. 47 – 49 ). Underside reddish brown, middle of meso- and metaventrite dark brown. Legs yellowish brown.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine and conspicuous, 1.0–2.0 diameters apart, with scattered short setae, interocular distance of eyes 0.63x head width ( Fig. 49 View FIGURES 47 – 55. 47 – 49 ).

Pronotal punctures fine and conspicuous, 1.5–2.5 diameters apart. Elytral surface polished, punctures very fine and shallow, smaller than those on pronotum, 2.0–4.0 diameters apart. Elytral margins moderately wide, hardly visible from above.

Prosternal surface mat and shagreened, punctures inconspicuous, with scattered long setae. Mesoventral surface shiny, punctures coarse and sparsely distributed with scattered short setae. Metaventrite with large and densely distributed punctures, 1.2–2.0 diameters apart. Elytral epipleuron broad, complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis long and slender, strongly curved, capsule broadening basally and with a small inner process ( Fig. 179 View FIGURES 178 – 186. 178 – 182 ); tegmen with penis guide slightly longer than paramere, in lateral view thin and straight, arcuately projected at base( Fig. 180 View FIGURES 178 – 186. 178 – 182 ); penis guide in ventral view parallel along 7/8 its length, then narrowing to apex ( Fig. 181 View FIGURES 178 – 186. 178 – 182 ); parameres long and slender.

Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous ( Fig. 182 View FIGURES 178 – 186. 178 – 182 ).
