Diagnosis.
This species is very similar to
S. jinpingensis
but can be distinguished from the latter by penis guide shorter than parameres and narrow in ventral view (
Figs 267–268
). But in
S
.
jinpingensis
, penis guide longer than parameres and wide in ventral view.
Description.
TL:
2.26–2.70 mm
, TW:
2.08–2.44 mm
, TH:
1.22–1.52 mm
, TL/TW: 1.09–1.11; PL/PW: 0.41– 0.42; EL/EW: 0.87–0.95; HW/TW: 0.38; PW/TW: 0.61.
Head, pronotum and scutellum yellow. Elytra predominantly yellow, each elytron with 4 small black rounded spots disposed as follows: spot 1 resting on the humeral callus (touching basal margin); spot 2 resting on 2/5 length of elytral suture (touching sutural margin); spot 3 resting on disc slightly posteriad of half length of elytron; spot 4 just before sutural apex (
Figs 101–103
). Underside uniformly yellow.
Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine, shallow, 1.5– 2.0 diameters apart, without short setae, interocular distance of eyes 0.61x head width (
Fig. 103
).
Pronotal punctures fine and shallow, 0.5–1.5 diameters apart. Elytral punctures fine, slightly smaller than those on pronotum, 1.5–2.5 diameters apart, with a row of large punctures along the suture. Elytral margins moderately wide, distinctly visible from above.
Prosternal surface slightly shagreened, punctures inconspicuous, with long sparse setae. Mesoventral surface shiny, punctures fine and inconspicuous. Metaventrite covered by coarse and dense punctures. Elytral epipleuron broad, complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.
Male genitalia: Penis short and stout, moderately curved at base, capsule moderately large and with a small inner process, apex with a thin blunt sclerotized and a membranous appendage (
Fig. 266
); tegmen with penis guide distinctly shorter than parameres, in lateral view stout and slightly arcuate, widest at base, gradually narrowing to apex (
Fig. 267
); penis guide in ventral view subparallel along its 3/4 length, then tapering to apex, apex rounded (
Fig. 268
); parameres slender and straight, apex moderately broadening, with dense setae apically.
Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous, each with sparse long terminal setae (
Fig. 269
).

Etymology.
The specific epithet is formed from the Latin adjective

, referring to parameres’ shapes.
