Pronotum: transverse; lateral margin straight, slightly diverging for basal ⅔ then rounding to anterior angle, canaliculate; anterior angle rectangular; posterior angle acute; anterior margin rounded anteriorly; disc subconvex, concave laterally; surface with sparse, rounded punctures; basal impression absent; pronotal length 1.4-1.6 mm; pronotal width 1.7-2.1 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; finely punctate-striate, punctures more impressed laterally; surface finely irregularly wrinkled; elytral length 4.4-4.7 mm; elytral width 2.3-2.7 mm. Venter: pro-, meso- and metasterna impunctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; apical abdominal sternite subangulate-emarginate in male, bisinuate in female.

Diagnosis.

This species falls into a group of bicolored species with a reddish pronotum which includes Cephaloleia abdominalis , Cephaloleia princeps , Cephaloleia steinhauseni , Cephaloleia susanae sp. n., and Cephaloleia teutonica . It can be distinguished from these species by the vertex of the head lacking a medial fovea but having a medial sulcus and by the pronotum with straight lateral margins which are not serrulate.

Host plant.
