( Figures 80–82 View FIGURES 74 – 82. 74 – 76 , 232–236 View FIGURES 227 – 236. 227 – 231 , 300 View FIGURE 300 )

Diagnosis. This species is very similar to S. denticulata in dorsal color pattern, but can be distinguished from latter by relatively small spots on elytra ( Fig. 80 View FIGURES 74 – 82. 74 – 76 ), long and slender penis ( Fig. 233 View FIGURES 227 – 236. 227 – 231 ), very short and slender parameres ( Figs 234–235 View FIGURES 227 – 236. 227 – 231 ). In S. denticulata , spots on elytra are large ( Fig. 83 View FIGURES 83 – 91. 83 – 85 ), parameres very wide and distinctly longer than penis guide ( Figs 238–240 View FIGURES 237 – 246. 237 – 241 ).

Description. TL: 2.27–2.54 mm, TW: 2.11–2.41 mm, TH: 1.22–1.38 mm, TL/TW: 1.05–1.08; PL/PW: 0.38– 0.40; EL/EW: 0.84–0.86; HW/TW: 0.37; PW/TW: 0.66.

Head reddish brown. Pronotum reddish brown, and scutellum dark brown. Elytra predominantly reddish brown, with moderately wide black band along lateral margins, band expanded at middle and apex of elytra, each elytron additionally with 4 black rounded spots disposed as follows: spot 1 near middle of basal margin (touching margin); spot 2 (largest one) resting on 2/5 length of suture; spot 3 (smallest one) on disc slightly posteriad of half length of elytron; spot 4 just before elytral apex ( Figs 80–82 View FIGURES 74 – 82. 74 – 76 ). Underside reddish brown, with metaventrite dark brown. Legs reddish brown.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures inconspicuous, 1.5– 2.5 diameters apart, with scattered short setae. Eyes small and coarsely faceted, interocular distance of eyes 0.59x head width ( Fig. 82 View FIGURES 74 – 82. 74 – 76 ).

Pronotal punctures fine and sparse, 1.0–2.0 diameters apart. Elytral punctures fine and sparsely distributed, distinctly smaller than those on pronotum, 3.0–4.0 diameters apart, with a row of large punctures along sutural and basal margins. Elytral margins narrow, visible from above.

Prosternal punctures inconspicuous, with long sparse setae. Mesoventral surface shiny, punctures fine and sparse, 2.0–2.5 diameters apart, with scattered short setae. Metaventrite covered by coarse and dense punctures distributed at center. Elytral epipleuron broad, complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis long and slender, widest at base, gradually narrowing to apex, capsule with a small inner process ( Fig. 233 View FIGURES 227 – 236. 227 – 231 ); tegmen with penis guide in lateral view thin and straight, 3x paramere length, apex slightly curved ( Fig. 234 View FIGURES 227 – 236. 227 – 231 ); penis guide in ventral view wide and flat, symmetrical, apex pointed ( Fig. 235 View FIGURES 227 – 236. 227 – 231 ); parameres very short with short setae apically.

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