Elongate; subdepressed; subparallel; black; pronotum, prosternum, and claws red. Head: vertex densely punctate, medial sulcus absent; keel present between antennal bases; frons not projecting; not depressed between eyes.

Pronotum: transverse; lateral margin sinuate then rounding to anterior angle, canaliculate; anterior angle rounded, slightly produced; posterior angle acute; apical margin straight; disc subconvex; disc with scattered, oval punctures, large medial area impunctate; basal impression present medially; pronotal length 0.9 mm; pronotal width 1.0 mm. Scutellum: triangular; impunctate. Elytron: lateral margin almost straight, margined, finely toothed; apex rounded; sutural angle with tooth; humerus rounded, not produced; slightly constricted behind humerus; puncture rows converging and uniting apically, except rows 1 and 10; rows 2-5 weakly punctate beyond middle; nearly impunctate at humerus; elytral length 2.7-3.1 mm; elytral width 1.4 mm. Venter: epipleuron wide, impunctate; prosternum punctate; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna 1-3 punctate laterally; 4-5 setose; suture between sterna 1 and 2 complete; last sternite with apical margin broadly emarginate medially in male, truncate in female; pygidium keeled.

Diagnosis.

This species is most similar to Cephaloleia ruficollis and Cephaloleia schmidti . It can be distinguished by the unicolorous elytra and by the vertex of the head not being depressed between the eyes.
