Diagnosis.

This species is similar to Cephaloleia abdominalis , Cephaloleia amazona , Cephaloleia princeps , Cephaloleia steinhauseni , and Cephaloleia teutonica . It can be distinguished by the straight lateral margins of the pronotum, by the vertex of the head having a medial carina, by the pronotum with a medial black longitudinal vitta, and by the finely serrulate lateral margins of the elytra.

Distribution.
