Description.

Elongate; subdepressed; shining; reddish-yellow; eyes and antennomeres 3-11 dark. Head: vertex impunctate, with deep fovea; frons not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 compressed, thick, longer than 2, truncate at apex, with short acute tooth at apex; 2 short, transverse; 3 longer than 1; 4-5 elongate, subequal in length, each shorter than 3; 6-10 subequal in length, each shorter than 4; 11 2 × length of 10, acutely pointed at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight in female, diverging in male, then rounding to anterior angle, canaliculate; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface densely punctate, punctures coarser basally; transverse basal impression present medially; pronotal length 2.1-2.4 mm; pronotal width 2.7-2.9 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, slightly margined; apex obtusely rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, punctures somewhat confused basally; elytral length 6.9-7.2 mm; elytral width 3.6-4.0 mm. Venter: prosternum impunctate; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin sinuate in male, obtusely rounded in female. Leg: femur and tibia punctate; tibia expanding apically, with fringe of setae on inner margin of apex. Total length: 9.0-10.1 mm.
