( Figs 1a–l View FIGURE 1 )

Diagnosis. This species can be easily separated from S. seminigra by the following characters: elytron yellow, with a large black spot situated at 1/3 elytral length to base. In S. seminigra , elytra are black in basal half and yellow in apical half, without dark spots. It is also similar to S. ovalis but can be separated from the latter by the bright yellow head and penis guide nearly as long as parameres. In S. ovalis , head is reddish brown and penis guide shorter than parameres.

Description. TL: 2.73–3.07mm, TW: 2.30–2.52mm, TH: 1.51–1.56mm, TL/TW: 1.19–1.22, PL/PW: 0.26–0.29, EL/EW: 0.88–0.89, HW/PW: 0.56–0.63, PW/TW: 0.63–0.66, HW/TW: 0.38–0.40, Eye W/HW: 0.54–0.59.

Head yellow. Pronotum, scutellar shield, and elytra bright yellow, with small dense punctures. Underside yellowish brown, except metaventrite and the middle part of the first ventrite blackish brown.

Body rounded, weakly convex, dosally shiny and glabrous ( Figs 2a–c View FIGURE 2 ). Head 0.39 times of elytral width (HW/ TW=1:2.6). Eyes finely faceted interocular distance 0.57 times of head width. Frons broad with punctures uniform and dense ( Fig. 2c View FIGURE 2 ).

Pronotum 0.65 times of elytral width (PW/TW=1:1.5), moderately transverse, punctures uniform ( Figs 2a, c View FIGURE 2 ). Elytra with uniform and dense punctures ( Figs 2a–c View FIGURE 2 ).

Ventrite 6 of posterior margin at middle slightly concave and ventrite 7 subtrianglar ( Fig. 2g View FIGURE 2 ).

Male genitalia ( Figs 2d–f View FIGURE 2 ): penis long and slender, apex pointed, penis capsule with inner arm reduced and outer arm well developed; tegmen with penis guide as long as parameres, in lateral view stout, widest at base, gradually narrowing to a pointed apex.

Type material. Holotype: ♂, Philippines, Baguio, Benguet, Baker ( USNM) . Paratypes: 6♀, same data as holotype ( USNM, ANIC) ; 1♂ 4♀, Philippines, Luzon– Benguet LaTrinidadv. 1914, G.Boellcher 6500’ ( MNHB) ; 1♀, Philippines 1600m, Mindanao, 30 km W of MARAMAG, 28–30. Dec. Bolm 1gt. 1990 ( BNHM) .
