Description.

Elongate; subparallel; subconvex; head, antennae, elytra, and venter black; pronotum red. Head: vertex densely punctate, medial sulcus absent; frons not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; an tennomere 1 clavate, subequal in length to 3; 2-3 elongate, 2 shorter than 1 or 3; 4-10 transverse, decreasing in length; 11 longer than 10, rounded at apex; 1-2 punctate; 3-11 setose. Pronotum: subquadrate; lateral margin straight for basal ½ then rounding to anterior angle, narrowly canaliculate; anterior angle acute, produced; posterior angle angulate; anterior margin emarginate behind head; disc subconvex, slightly depressed behind middle; surface sparsely punctate, punctures subovate, large; pronotal length 1.0-1.1 mm; pronotal width 1.3-1.4 mm. Scutellum: pentagonal, micropunctate. Elytron: lateral margin nearly straight, smooth, margined; apex rounded, minutely serrulate, emarginate at suture; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; subconvex, slightly flattened along suture; moderately punctate-striate, punctures large, punctures near apex smaller and less impressed than those on disc, rows converge and unite apically; elytral length 3.8-4.1 mm; elytral width 1.9-2.0 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna 1-4 punctate laterally, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin broadly truncate-emarginate, sinuate medially in male, truncate in female. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 5.1-5.3 mm.

Diagnosis.

This species is similar to Cephaloleia atriceps and Cephaloleia schmidti . It can be distinguished by the unicolorous elytra, by the vertex of the head being depressed between the eyes, and by the suture between abdominal sterna 1 and 2 being obsolete medially.

Distribution.
