Description.

Elongate; subparallel; subdepressed; shining; black; basal ⅓ of pronotum and longitudinal vitta on elytra yellowish; scutellum, venter, and legs (except tarsi and tibio-femoral joint darker) yellowish. Head: vertex finely punctate, medial carina present; frons not projecting; depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, elongate, 2 × length of 2; 2 elongate, cylindrical; 3 cylindrical, subequal in length to 1; 4-5 elongate, cylindrical, decreasing in length; 6-7 transverse, decreasing in length; 8-10 transverse, subequal in length, each shorter than 7; 11 2 × length of 10, rounded at apex; 1-2 punctate with scattered setae, 3-11 setose. Pronotum: subquadrate, slightly narrowed basally; lateral margin straight then rounding to anterior angle, canaliculate; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface coarsely punctate; transverse basal impression present medially; pronotal length 1.5-1.7 mm; pronotal width 1.9-2.1 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded, emarginate at sutural angle; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; declivity beginning just behind humerus at puncture row 7 not edged with faint carina; flattened along suture; moderately punctate-striate, rows converge and unite apically; elytral length 5.1-5.4 mm; elytral width 2.1-2.3 mm. Venter: pro-, meso-, and metasterna impunctate; abdominal sterna impunctate with row of setae apically; suture between sterna 1 and 2 entirely obsolete; last sternite with apical margin broadly emarginate medially in male, bisinuate in female. Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 6.5-7.0 mm.

Diagnosis.

This species is similar to Cephaloleia eximia and Cephaloleia pulchella . It can be distinguished by the suture between abdominal sterna 1 and 2 being obsolete and by the pro-, meso-, and metasterna being impunctate.
