( Figures 77–79 View FIGURES 74 – 82. 74 – 76 , 227–231 View FIGURES 227 – 236. 227 – 231 , 300 View FIGURE 300 )

Diagnosis. This species is similar to S. illecebrosa in dorsal color pattern, but can be distinguished from the latter as follow: pronotum yellow without black spot, elytron with a row of large punctures along the suture ( Fig. 77 View FIGURES 74 – 82. 74 – 76 ), parameres 1/2 of penis guide length ( Fig. 229 View FIGURES 227 – 236. 227 – 231 ), and penis very long and slender ( Fig. 228 View FIGURES 227 – 236. 227 – 231 ). In S. illecebrosa , pronotum is yellow with a black spot, elytra without large punctures ( Fig. 56 View FIGURES 56 – 64. 56 – 58 ), paramere 3/4 of penis guide length ( Fig.194 View FIGURES 187 – 196. 187 – 191 ), and penis shorter ( Fig. 193 View FIGURES 187 – 196. 187 – 191 ).

Description. TL: 2.08 mm, TW: 1.81 mm, TH: 1.05 mm, TL/TW: 1.15; PL/PW: 0.44; EL/EW: 0.91; HW/TW: 0.40; PW/TW: 0.64.

Head yellowish brown, with mouthparts yellow. Pronotum yellowish brown and scutellum dark brown. Elytra predominantly yellowish brown, each elytron with 4 large black rounded spots disposed as follows ( Figs 77–79 View FIGURES 74 – 82. 74 – 76 ): spot 1 resting on the humeral callus (touching basal margin); spot 2 resting on 2/5 length of elytral suture (touching margin); spot 3 resting on disc slightly posteriad of half length of elytron; spot 4 just before sutural apex. Underside brown, elytral epipleuron yellowish brown. Legs yellow.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures medium and densely distributed, 0.5–2.0 diameters apart, with short sparse setae, interocular distance of eyes 0.57x head width ( Fig. 79 View FIGURES 74 – 82. 74 – 76 ).

Pronotal punctures fine, 1.5–2.5 diameters apart, slightly smaller than those on head. Elytral surface polished, punctures fine and sparse, similar to those on pronotum, 1.5–2.5 diameters apart, with a row of large punctures along basal 1/2 of suture. Elytral margins moderately wide, distinctly visible from above.

Prosternal surface slightly shagreened, punctures inconspicuous, with long sparse setae. Mesoventral surface shiny, with several large punctures. Metaventrite covered by coarse and dense punctures distributed at center. Elytral epipleuron broad, complete to apex, moderately foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis very long and soft, moderately curved at base, capsule slightly broadening basally and with a thin inner process ( Fig. 228 View FIGURES 227 – 236. 227 – 231 ); tegmen with penis guide in lateral view slender, widest at base, narrowing to apex, 2x parameres length ( Fig. 229 View FIGURES 227 – 236. 227 – 231 ); penis guide in ventral view thin, widest at base, gradually narrowing to apex ( Fig. 230 View FIGURES 227 – 236. 227 – 231 ); parameres slender, with sparse setae apically.

Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous, each with sparse long terminal setae ( Fig. 231 View FIGURES 227 – 236. 227 – 231 ).
