( Figures 56–58 View FIGURES 56 – 64. 56 – 58 , 192–196 View FIGURES 187 – 196. 187 – 191 , 298 View FIGURE 298 )

Diagnosis. This species is similar to S. punctata in dorsal color pattern, but can be distinguished from the latter as follows: pronotum is yellow with a rounded black middle spot, spot 2 close but not touch elytral suture ( Fig. 56 View FIGURES 56 – 64. 56 – 58 ), penis short ( Fig. 193 View FIGURES 187 – 196. 187 – 191 ) and penis guide 1.25x longer than parameres ( Fig. 194 View FIGURES 187 – 196. 187 – 191 ). In S. punctata , pronotum is black, spot 2 touches elytral suture ( Figs 59–61 View FIGURES 56 – 64. 56 – 58 ), penis long ( Fig. 198 View FIGURES 197 – 205. 197 – 200 ) and penis guide slightly longer than parameres ( Fig. 199 View FIGURES 197 – 205. 197 – 200 ).

Description. TL: 2.24 mm, TW: 2.08 mm, TH: 1.19 mm, TL/TW: 1.08; PL/PW: 0.45; EL/EW: 0.84; HW/TW: 0.37; PW/TW: 0.60.

Head yellow. Pronotum yellow with a rounded black middle spot. Scutellum yellowish brown. Elytra predominantly yellow, with brown band along basal and lateral margins, band expanded at apex of elytra, each elytron with 4 large black rounded spots disposed as follows: spot 1 resting on the humeral callus (not touching basal margin); spot 2 resting at 2/5 length of elytral suture (almost touching margin); spot 3 resting on disc slightly posterad of half length of elytron; spot 4 just before sutural apex ( Figs 56–58 View FIGURES 56 – 64. 56 – 58 ). Underside yellow.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine and shallow, 1.0–1.5 diameters apart, with scattered short setae, interocular distance of eyes 0.61x head width ( Fig. 58 View FIGURES 56 – 64. 56 – 58 ).

Pronotal punctures fine, 1.5–2.5 diameters apart. Elytral surface polished, punctures uniformly fine, similar to those on pronotum, 1.5–2.0 diameters apart. Elytral margins moderately wide, distinctly visible from above.

Prosternal surface slightly shagreened, punctures inconspicuous, with scattered long setae. Mesoventral surface shiny, punctures medium, 0.5–1.5 diameters apart. Metaventrite shiny, covered by large and dense punctures distributed at center, 0.5–1.5 diameters apart. Elytral epipleuron broad, complete to apex, very feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis short and slender, moderately curved at base, capsule inconspicuous, apex pointed ( Fig. 193 View FIGURES 187 – 196. 187 – 191 ); tegmen with penis guide in lateral view slender, widest at base, narrowing to apex, 1.25x parameres length ( Fig. 194 View FIGURES 187 – 196. 187 – 191 ); penis guide in ventral view widest at base, gradually narrowing to apex ( Fig. 195 View FIGURES 187 – 196. 187 – 191 ); parameres slender and straight, with sparse setae apically.

Female genitalia: Ovipositor elongate and slender, styli inconspicuous, each with sparse long terminal setae ( Fig. 196 View FIGURES 187 – 196. 187 – 191 ).

Holotype: 1male, China, Guizhou: Jiaomi, Taijiang , [26°39.92′N, 108°19.44′E], ca 1150m, 14.x.2008, Liang JB leg. ( SCAU) GoogleMaps . Paratype: 1female, same data as holotype ( SCAU) GoogleMaps .

Distribution. China: Guizhou.

Etymology. The name of this new species is formed from the Latin adjective illecebrosus, referring to its beautiful appearance.
