Aedeagus examined in 14 males.
REDESCRIPTION. As for the previous species except as follows: BL 11.9–15.3 mm. Body ( Fig. 73 View Figs 70—75 ) dorsally black to brown, with entire head and pronotum red in the latter case; head pattern similar.Head and pronotum rather shiny due to superficial microsculpture. Pilosity (and punctures on head and pronotum) fairly dense.Head rather densely punctate along sides, distinctly in front of supra-ocular seta, glabrous medially.Pronotum moderately densely and evenly pilose or slightly less densely on disc, pilosity very distinct on notopleura in at least basal half. Propleura in apical half and elytra sparsely to moderately pilose.
Head: genae rather long, slightly convex and slightly more distinct than in the other species of the group due to a bit less obtuse gena-to-neck angle; frontal foveae not extended onto clypeus.
Pronotum similar, except for notopleura often tumid and sides parallel in front of right basal angles.
Elytra on average narrower relative to pronotum. Ridges 1– 5 well-developed, widened toward base, subcostate and shiny in at least basal 1/4–1/3. Chetotaxy similar (varying, often with more than one seta along interval 5).
Abdomen ( Figs 8 View Figs 1—15 , 20 View Figs 16—30 , 49 View Figs 46—53 ): Tergite VII with coarse punctures barely denser and very few fine punctures only traceable here and there; with a row of 13–19 apical setae in female.
Aedeagus ( Figs 64, 68 View Figs 54—69 ): apex in lateral view tapered, in lateral view symmetric, long, triangular, with sides barely constricted before rather pointed tip. Internal sac with basal bulbs small; proximal ones in dorsal view concealed with the body, in lateral view, adjoining the body basally.
Female gonocoxite IX long, ensiform and subclavate, rather strongly curved laterad ( Fig. 38 View Figs 31—45 , 49 View Figs 46—53 ). Receptacle not Y-shaped owing to horns incrassate, with one of them absorbed as in Fig.51 View Figs 46—53 .
GEOGRAPHIC DISTRIBUTION.Southern China (Guanxi), northern Vietnam (Cao Bang, Vinh Phuc, and Lao Cai provinces); supposedly northern Laos and Yunnan, China.
HABITATS AND HABITS. A high-montane species that dwell in rain broad-leaved forests with considerable admixture of bamboo trees at 1600–2000 m, occasionally at 1200 m, altitudes. It has been found to be sympatric with S. tamdaoensis and S. glabricollis sp.n., while sharing some habitats with S. tamdaoensis , in the Phia Oac National Park.
