Description.

Narrowly elongate; subparallel; subdepressed; dorsum black, venter pale yellow; vertex of head black, frons yellowish; antennomeres 1-3 yellowish, 4-6 black, 7-11 whitish; lateral margins of pronotum, scutellum, and base of elytra with broad yellowish band, middle and apex of elytra with broad yellowish band; legs pale yellow. Head: vertex finely punctate, medial sulcus present; frons concave, not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, 2 × length 2; 2 slightly elongate; 3 slightly longer than 2; 4-6 elongate, subequal in length, each ¾ length of 3; 7-10 subequal in length, each shorter than 6; 11 2 × length 10, rounded at apex; 1-6 punctate with scattered setae; 7-11 setose. Pronotum: quadrate; lateral margin slightly sinuate then rounding to anterior angle, canaliculate; anterior angle rounded; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface deeply, irregularly punctate, punctures more dense laterally, punctures moderate to large; basal impression absent; pronotal length 1.7-1.9 mm; pronotal width 2.2-2.4 mm. Scutellum: elongate pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex slightly rounded, sutural angle emarginate, without tooth; humerus rounded, not produced; slightly constricted behind humerus; subconvex, disc flattened; shallowly punctate-striate, punctures in irregular rows; elytral length 6.4-6.8 mm; elytral width 3.0-3.2 mm. Venter: pro-, meso-, and metasterna impunctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin concave-emarginate in male, broadly emarginate in female. Leg: slender; impunctate; femur robust; tibia with fringe of setae on inner margin of apex. Total length: 8.8-9.2 mm.

Diagnosis.

This species is similar to Cephaloleia amba sp. n. It can be distinguished by the smooth lateral margins of the pronotum and by antennomere 1 being twice the length of 2.
