TL: 2.70–2.90 mm , TW: 2.31–2.67 mm , TH: 1.42–1.45 mm , TL/TW: 1.09–1.17; PL/PW: 0.40– 0.41; EL/EW: 0.89–0.97; HW/TW: 0.33; PW/TW: 0.60. Head reddish brown. Pronotum reddish brown, and scutellum dark brown. Elytron predominantly reddish brown, with two large yellow irregular discal spots resting one near base and one near apex, each elytron additionally with 8 small black spots around the margins of yellow spots as in Figs 107–109 . Underside brown, elytral epipleuron and legs reddish brown. Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine and shallow, 2.0–3.5 diameters apart, with short sparse setae, interocular distance of eyes 0.63x head width ( Fig. 109 ). Pronotal punctures very fine, 2.5–4.0 diameters apart. Elytral punctures very fine and shallow, similar to those on pronotum, 2.0–3.0 diameters apart. Elytral margins narrow, visible from above. Prosternal punctures inconspicuous, with long sparse setae. Mesoventral surface shiny, punctures inconspicuous. Metaventrite shiny, punctures inconspicuous. Elytral epipleuron broad, complete to apex, not foveate to accommodate femoral tips of hind legs. Wings well-developed. Male genitalia: Penis slender, capsule broadening basally and with a small inner process, apex taenia-shaped ( Fig. 276 ); tegmen with penis guide longer than parameres, in lateral view straight, widest at base, gradually narrowing to apex, with a wire-like process at apical 1/4 ( Fig. 277 ); penis guide in ventral view straight, slightly narrowed at apical 1/5, with 3 pairs of denticles, apex rounded ( Fig. 278 ); parameres extremely thin. Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous, each with many long terminal setae ( Fig. 279 ).
