Description.
Large, elongate; subparallel; subconvex; head (except frons reddish-yellow), antennae, and scutellum black; pronotum reddish-yellow, often with variable black markings; elytra varies from entirely reddish-yellow, to variable black markings, to entirely black; venter with prosternum red; meso- and metasterna red medially, black laterally, abdominal sterna black; leg with femur pale basally, dark apically, tibiae and tarsi darker. Head: vertex impunctate, with longitudinal Y-shaped medial carina; frons finely punctate, not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 elongate, robust, clavate, longer than 2 and 3 combined; 2 ovate; 3 longer than 2, compressed, triangular; 4-10 transverse, decreasing in length; 11 2 × length of 10, pointed at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, narrowly canaliculate; anterior angle not produced, acute; posterior angle acute; apical margin straight; disc subconvex, impunctate; surface punctate laterally; basal impression absent; pronotal length 1.3-1.5 mm; pronotal width 1.5-1.6 mm. Scutellum: acutely triangular; alutaceous. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; flattened along suture; moderately punctate-striate, punctation obsolete at humerus, rows converge and unite apically; elytral length 5.4-6.1 mm; elytral width 1.73-2.3 mm. Venter: prosternum impunctate; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin sinuate medially in male, truncate in female. Leg: slender; femur and tibia sparsely punctate; tibia with fringe of setae on inner margin of apex. Total length: 6.8-7.8 mm.
Diagnosis.
This species is similar to Cephaloleia instabilis . It can be distinguished by antennomere 2 being triangular, by the pronotum being uniformly punctate, and by the elytra lacking a declivity at puncture row 7.
Host plant.
Adults have been collected from Heliconia imbricata (Kuntze) Baker, Heliconia latispatha Benth. ( Staines 1996); Heliconia trichocarpa G. S. Daniels and F. G. Stiles, Heliconia wilsonii G. S.
