Pronotum: transverse; lateral margin straight, divergent for basal ⅔ then rounding to anterior angle, narrowly margined; anterior angle rounded, slightly produced; posterior angle acute, slightly produced; anterior margin straight; disc subconvex; surface with few scattered punctures laterally; basal impression absent; pronotal length 1.0 mm; pronotal width 1.4 mm. Scutellum: triangular; pointed at apex; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, rows converge and unite apically; elytral length 4.4 mm; elytral width 1.9 mm. Venter: pro- and mesosterna impunctate; metasternum impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete.

Diagnosis.

This species is similar to Cephaloleia eumorpha and Cephaloleia interrupta . It can be distinguished by antennomere 1 being subequal in length to 2 to 4 combined and by the black color.
