( Figures 95–97 , 255–259 , 302 ) Diagnosis. This species is very similar to S. linguiformis in dorsal color pattern, but can be distinguished from the latter as follow: spots on the humeral callus do not touch anterior elytral margins ( Fig. 95 ), penis is short and stout ( Fig. 256 ), and penis guide of tegmen is slightly longer than parameres ( Fig. 257 ). But in S. linguiformis , spots on the humeral callus touch anterior elytral margins, penis is long and slender, and penis guide of tegmen is distinctly shorter than parameres. Description. TL: 2.51–2.93 mm , TW: 2.24–2.60 mm , TH: 1.48–1.71 mm , TL/TW: 1.12–1.13; PL/PW: 0.42– 0.43; EL/EW: 0.88–0.92; HW/TW: 0.38; PW/TW: 0.63. Head, pronotum and scutellum yellowish brown. Elytra predominantly yellow, each elytron with 4 small black rounded spots disposed as follows: spot 1 resting on the humeral callus (not touching basal margin); spot 2 resting near 2/5 length of elytral suture, not touching sutural margin, the diameter of the spot about 1/2 its distance from suture; spot 3 resting on disc slightly posteriad of half length of elytron; spot 4 just before sutural apex ( Figs 95– 97 ). Underside yellowish brown, with elytral epipleuron yellow. Legs yellowish brown. Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine, shallow, inconspicuous, 1.0–1.5 diameters apart, without short sparse setae, interocular distance of eyes 0.70x head width ( Fig. 97 ). Pronotal punctures fine and shallow, 0.5–1.5 diameters apart. Elytral punctures fine and sparsely distributed, smaller than those on pronotum, 2.0–4.0 diameters apart. Elytral margins moderately narrow, visible from above. Prosternal surface slightly shagreened, punctures inconspicuous, with scattered long setae. Mesoventral surface shiny, punctures fine and inconspicuous. Metaventrite shiny, covered by coarse and dense punctures distributed at center. Elytral epipleuron broad and complete to apex, strongly foveate to accommodate femoral tips of hind legs. Wings well-developed. Male genitalia: Penis short and very stout, moderately curved at base, capsule inconspicuous, apex rounded ( Fig. 256 ); tegmen with penis guide slightly longer than parameres, in lateral view stout and straight, widest at base, gradually narrowing to apex ( Fig. 257 ); penis guide in ventral view widest at base, gradually narrowing to apex ( Fig. 258 ); parameres slender and straight, with dense setae apically. Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous, each with sparse long terminal setae ( Fig. 259 ).

Distribution. China : Yunnan . Etymology. The specific epithet is formed from the Latin numeral octo and adjective punctatus , referring to elytra with eight black spots.
