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.
Diagnosis
This species is similar to Cephaloleia hnigrum and Cephaloleia recondita. It can be distingusihed by the lateral margin of the elytra having black markings extending to puncture row 6.
Distribution
