( Figures 74–76 View FIGURES 74 – 82. 74 – 76 , 222–226 View FIGURES 217 – 226. 217 – 221 , 300 View FIGURE 300 )

Diagnosis. This species is very similar to S. denticulata in dorsal color pattern, but can be distinguished from the latter by slender parameres and nipple-shaped apex of penis guide ( Figs 224–225 View FIGURES 217 – 226. 217 – 221 ). In S. denticulata , parameres are very wide and apex of penis guide is pointed ( Figs 239–240 View FIGURES 237 – 246. 237 – 241 ).

Description. TL: 2.24–2.97 mm, TW: 2.01–2.57 mm, TH: 1.19–1.62 mm, TL/TW: 1.11–1.15; PL/PW: 0.43– 0.44; EL/EW: 0.90–0.92; HW/TW: 0.37; PW/TW: 0.62.

Head yellowish brown, with mouthparts yellow. Pronotum dark red, scutellum dark brown. Elytra reddish brown, with moderately wide dark red band along lateral margin; band expanded at middle of lateral margin and at elytral apex. Elytra with 6 moderately large, black rounded spots disposed as follows: a pair resting on the humeral calli (touching basal margin); a pair resting on disc slightly posteriad of half length of elytron; one resting at 2/5 length of elytral suture; one just before sutural apex ( Figs 74–76 View FIGURES 74 – 82. 74 – 76 ). Underside dark brown, elytral epipleuron reddish brown. Legs yellowish brown.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine and shallow, 0.2–1.0 diameters apart, with short sparse setae, interocular distance of eyes 0.62x head width ( Fig. 76 View FIGURES 74 – 82. 74 – 76 ).

Pronotal punctures fine and dense, 0.5–1.5 diameters apart. Elytral punctures very fine and sparse, distinctly smaller than those on pronotum, 2.0–3.0 diameters apart, with two arcuate rows of large punctures near suture at mid length. Elytral margins moderately explanate, entirely visible from above.

Prosternal surface mat and shagreened, punctures inconspicuous. Mesoventral surface shining, punctures fine shallow. Metaventrite covered by coarse and dense punctures distributed at center. Elytral epipleuron broad and complete to apex, distinctly foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis short and stout, slightly curved at base, capsule broadening basally and with a small inner process, apex slightly membranous ( Fig. 223 View FIGURES 217 – 226. 217 – 221 ); tegmen with penis guide slightly longer than parameres, in lateral view stout, widest at base, gradually tapering to apex ( Fig. 224 View FIGURES 217 – 226. 217 – 221 ); penis guide in ventral view short and stout, subparallel along its 6/7 length, then narrowed, apex nipple-shape ( Fig. 225 View FIGURES 217 – 226. 217 – 221 ); parameres slender, almost straight, with short sparse setae apically.

Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous ( Fig. 226 View FIGURES 217 – 226. 217 – 221 ).
