Description.

Elongate; subparallel; subdepressed; yellowish; head, antennae, and pronotum (except paler lateral and basal margins) black; elytra yellowish with lateral and apical margins black and black transverse band beyond middle; scutellum, venter, and legs yellowish. Head: vertex sparsely, finely punctate, medial sulcus absent; frons not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, 2 × length of 2; 2 subglobose; 3-4 elongate, subequal in length, each slightly longer than 2; 5-10 subequal in length, each shorter than 3; 11 2 × length 10, pointed at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: subquadrate; lateral margin straight then rounding to anterior angle, canaliculate; anterior angle slightly angulate, not produced; posterior angle acute; anterior margin straight; disc subconvex; surface finely punctate laterally, nearly impunctate on disc; transverse basal impression present medially; pronotal length 1.3-1.7 mm; pronotal width 1.5-1.9 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle with small tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, rows confused basally, scutellar row long; declivity beginning just behind humerus at puncture row 7 edged with faint carina; elytral length 5.3-5.7 mm; elytral width 2.0-2.2 mm. Venter: pro-, meso-, and metasterna punctate, each puncture with pale seta; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin rounded in male, truncate in female. Leg: slender; punctate; tibia with seta in each puncture and fringe of setae at apex. Total length: 6.8-7.2 mm.
