Serangium magnipunctatum Wang & Ren

TL: 2.09–2.18mm, TW: 1.75–1.85mm, TH: 1.02–1.05mm, TL/TW: 1.18–1.20; PL/PW: 0.47–0.49; EL/EW: 0.96. Body minute, hemispherical, dorsum strongly convex, glabrous (Fig. 15). Head yellow, pronotum reddish brown to black, except light-colored anterior angles and basal margin. Scutellum reddish brown to black. Elytra red to black, sometimes elytra black with median part red. Underside reddish brown and legs yellow. Head transverse and ventrally flattened, 0.42× elytral width (HW/EW=1: 2.41); punctures on frons fine and conspicuous, separated by 1.5–5.0 times their diameter, with short sparse setae; eyes moderately large and coarsely faceted, widest interocular distance 0.45× head width. Antenna 9-segmented, terminal segment large, spatulately elongate. Pronotum short and strongly transverse, 0.72× elytral width (PW/EW=1: 1.39), sparsely covered in fine punctures associated with long sparse setae, punctures smaller than those on head, separated by 2.0–4.0 times their diameter. Elytra with a few large inner punctures at basal margins and two rows of large punctures along elytral suture. Pro- and mesoventrites mat and weakly furrowed, with short sparse setae. Metaventrite shiny and glabrous, basal half with distinctly median discrimen; punctures around median discrimen large and dense, with short thick setae. Male genitalia. Penis strongly curved in whole length, apex shortly narrowing and rounded, penis capsule indistinctly (Fig. 37). Tegmen rather slender and strongly asymmetrical (Figs 38–39). Penis guide in ventral view flattened and tongue-shape (Fig. 39). Left paramere in ventral view very short bearing a few long setae, and right piece short and stout, distinctly projecting, bearing a few long setae (Fig. 39). Penis guide in lateral view thin and straight, apex pointed. Right paramere in lateral view short, about 1/3 of penis guide (Fig. 38). Female genitalia. Genital plate elongate triangular with a rounded apex, sparsely hairy on the apical portion, stylus long, bearing few setae (Fig. 41). Spermatheca divided into two parts, one of which is somewhat globular with a feeble constriction and two small pinch-like projections, the other is tubular, becoming slightly more slender distally (Fig. 40).
