(Figures 71–73, 217–221, 300)
Diagnosis. This species is very similar to S. denticulata in dorsal color pattern, but can be distinguished from the latter by elytra without large black mid sutural spot (Fig. 71) and rather wide penis and penis guide (Figs 218–220). Description. TL: 2.67–2.90 mm, TW: 2.37–2.54 mm, TH: 1.19–1.38 mm, TL/TW: 1.13–1.14; PL/PW: 0.42–0.43; EL/EW: 0.89–0.92; HW/TW: 0.36; PW/TW: 0.64.
Head yellowish brown, with mouthparts and antenna yellow. Dorsal color pattern as follows (Figs 71–73): Pronotum yellowish brown, scutellum dark reddish brown. Elytra predominantly yellow, with moderately wide reddish band along anterior, lateral margins; band abruptly angularly expanded at middle of lateral margin and at elytral apex; sutural band narrow, dark reddish brown, abruptly expanded medially. Each elytron with 2 black rounded spots disposed as follows: one resting at middle of basal margin, touching basal band, another one on disc slightly beyond half length of elytron. Underside yellow; pronotal hypomeron and elytral epipleuron yellowish brown; meso- and metaventrite reddish brown. Legs yellow.
Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures medium and dense, with very short setae, interocular distance of eyes 0.64x head width.
Pronotal punctures fine and dense, slightly smaller than those on head, 0.8–2.0 diameters apart. Elytral punctures similar to those on pronotum, with a row large dark punctures parallel to sutural, basal, lateral margins. 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 covered by coarse and sparse punctures. Elytral epipleuron broad, narrowing posteriorly but complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.
Male genitalia: Penis short and very stout, strongly curved, capsule with small inner process and without outer one, apex slightly narrow and truncate (Fig. 218); tegmen with penis guide distinctly longer than parameres, in lateral view very fat in basal 1/2, then gradually tapering to apex (Fig. 219); penis guide in ventral view symmetrical, very wide and subparallel at basal 7/8, then strongly narrowing to apex, apex finger-like (Fig. 220); parameres slender, almost straight, with moderately long setae apically.
Female genitalia: Ovipositor elongate and narrowly triangular, styli highly reduced, each with several long terminal setae (Fig. 221).
Holotype: 1male, China, Hainan: Wuzhishan, [18°47.07′N, 109°31.97′E], ca 700m, 24.vii.2006, Wang XM leg (SCAU). Paratypes (16): Hainan: 6males, 7females, same data as holotype; 1female, Diaoluoshan National Natural Reserve, Lingshui, [18°43.57′N, 109°52.25′E], ca 980m, 26.vii.2006, Wang XM et al. leg. (SCAU); 2females, Diaoluoshan National Natural Reserve, Lingshui, [18°43.57′N, 109°52.25′E], ca 980m, 8.v.2005, Wang XM leg (SCAU).
Distribution. China: Hainan.
Etymology. The specific epithet is formed from the Latin adjective latissimum (very wide), referring to extremely wide penis and penis guide.
