( Figures 38–40 , 164–168 , 297 ) Diagnosis. This species is very similar to S. ruficeps but can be distinguished as follow: margins of humeral spots irregular ( Fig. 38 ), penis short ( Fig. 165 ), penis guide longer than parameres with truncate apex ( Figs 166–167 ). In S. ruficeps , the margins of humeral spots are smooth ( Fig. 44 ), the penis is long and slender ( Fig. 175 ) and the penis guide shorter than parameres with apex rounded ( Figs 176–177 ). Description. TL: 2.18–2.27 mm , TW: 1.91–2.11 mm , TH: 1.01–1.05 mm , TL/TW: 1.08–1.14; PL/PW: 0.43– 0.44; EL/EW: 0.84–0.93; HW/TW: 0.36; PW/TW: 0.61. Head orange. Dorsal color pattern as follows ( Figs. 38–40 ): Pronotum and scutellum brown. Elytra predominantly brown, with yellowish brown lateral margin. Each elytron with 2 large yellowish spots disposed as follows: anterior very large, irregular, at middle of basal margin (touching margin), posterior small, 1/2 size of anterior, resting on apical third. Underside yellow; meso- and metaventrite yellowish brown. Legs yellow. In darker specimens, head reddish brown, pronotum and ground color of elytra nearly dark, spots on elytra red. Underside reddish brown; meso- and metaventrite black brown. Legs reddish brown. Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine with scattered short setae, interocular distance of eyes 0.61x head width ( Fig. 40 ). Pronotal punctures very fine but dense, 2.0–3.0 diameters apart. Elytral punctures slightly larger than those on pronotum, 2.0–3.0 diameters apart. Elytral margins narrowly explanate, entirely visible from above. Prosternal punctures inconspicuous, with long sparse setae. Mesoventral surface mat and slightly shagreened, with sparse short setae. Metaventrite with moderately coarse and sparsely distributed punctate. Elytral epipleuron broad, complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings well-developed. Male genitalia: Penis slender, capsule with small inner process and without outer one, apex strongly curved ( Fig. 165 ); tegmen with penis guide distinctly longer than parameres, in lateral view stout, widest at base, apical third slightly bend, apex pointed ( Fig. 166 ); penis guide in ventral view short and stout, widest at base, narrowing to apex, apex truncated ( Fig. 167 ); parameres very slender, almost straight, with short setae apically. Female genitalia: Ovipositor elongate and triangular, styli highly reduced, each with several long terminal setae ( Fig. 168 ).
