Pronotum: subquadrate; lateral margin straight for basal 4/5 then rounding to anterior angle, canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc subconvex; surface strongly, sparsely punctate, nearly impunctate medially and anteriorly; basal impression absent; pronotal length 0.6–0.8 mm; pronotal width 0.7–0.9 mm. Scutellum: pentagonal; finely punctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle with minute tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate; suture subsulcate; elytral length 2.1–2.3 mm; elytral width 0.9–1.0 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin emarginate medially in male, rounded, entire in female. Leg: short, robust; tibia punctate, each puncture with pale seta; with fringe of setae on inner margin of apex. Total length: 2.9–3.1 mm.
