TL:
2.24–2.51 mm
, TW:
2.08–2.27 mm
, TH:
1.15–1.38 mm
, TL/TW: 1.08–1.10; PL/PW: 0.40– 0.41; EL/EW: 0.84–0.87; HW/TW: 0.35; PW/TW: 0.67.

Pronotal punctures fine and densely distributed, separated by 1.0–2.0 diameters. Elytral punctures very fine and shallow, slightly smaller than those on pronotum, 2.5–5.0 diameters apart, with a row of large punctures along the suture, moderately arcuate medially. Elytral margins wide, visible from above.
Prosternum with fine punctures and scattered long setae. Mesoventral punctures large and densely distributed, 0.2–0.5 diameters apart. Metaventrite shiny and broad, covered by coarse and dense punctures distributed at center Elytral epipleuron broad and complete to apex, distinctly foveate to accommodate femoral tips of hind legs. Wings well-developed.
Male genitalia: Penis short, capsule slightly broadening basally and with a small inner process, apex curved with several denticles (
Figs 145–146
); tegmen with penis guide slightly longer than paramere, in lateral view straight, widest at base, gradually narrowing to apex (
