Supplementary description
Male (Fig. 1): Length: 21.0–28.0 mm, humeral width: 6.0–9.0 mm. Female (Fig. 2): Length: 30.0–34.0 mm, humeral width: 9.0–10.5 mm. The elytral maculae of this species is variable but generally as follows: besides some scattered small, round, yellow spots, each elytron provided with three main, bright yellow, well-defined, longitudinal but somewhat irregularly shaped maculae on basal one third, a little behind middle and near apex (Fig. 3); the middle macula commonly fused with the hind one as the holotype, but sometimes attach to the front one (Fig. 4). Antenna with 3rd antennomere twice as long as scape, slightly shorter than 4th in male while slightly longer than 4th in female; relative length of antennomeres as follows: male: 5.5 : 1.0 : 11.8 : 12.1 : 11.4 : 10.3 : 10.1 : 9.1 : 8.7 : 8.4 : 11.9; female: 4.7 : 1.0 : 9.9 : 9.4 : 8.0 : 7.1 : 6.4 : 5.7 : 5.6 : 5.3 : 7.1. Pronotum broader than long, 0.8 times as long as basal width, the width across lateral spines about 1.3 times of basal width; lateral spine long, thickened at base with acute apex; disk smooth, with several fine setigerous granules behind middle. Elytra ca. 1.8 times as wide as pronotal base, 2.7 times as long as humeral width, with some very fine granules at base. Male genitalia (Figs 7–10). Tegmen (Fig. 7) in lateral view strongly curved near base, ca. 3.5 mm in length, rhombic in shape and widest behind middle in ventral view; lateral lobes ca. two-ninths of total length of tegmen, provided with long setae on apical half. Median lobe (Fig. 8) slightly shorter than tegmen; moderately curved in lateral view; apex rounded subacuminate in antero-dorsal view. Tergite VIII (Fig. 9) nearly as broad as long, apex distinctly emarginate, with moderately long setae. Endophallus in non-everted condition (Fig. 10) long, about 3 times as long as median lobe, with 3 membranous parts, BPH, MPH and APH; BMP short, about one quarter of the length of median lobe; MPH long, about 2.7 times as long as median lobe, strongly curved at basal two-thirds, with MT and CT fused each other, of which delimited from PB by a distinct constriction; MT+CT sparsely provided with small spicules which become denser near swollen apex; PB provided with same kind of spicules as MT+CT, which become denser at apical half, basal part of PB rather narrow, only 0.35 times as wide as anterior part; APH short, cylindrical in shape. Ejaculatory ducts double.
