Description.

Elongate; subparallel; subdepressed; yellowish-brown, antennae black, except apical three antennomeres which are brownish; head near eyes black; pronotum with fine narrow black margins; scutellum and elytral suture black, elytral lateral margin dark reddish-brown. Head: vertex with scattered punctures, medial sulcus absent; frons triangular, projecting; not depressed between eyes. Antenna: reaches base of the pronotum; slender; antennomere 1 longest, expanding apically, clavate (especially in male); 2-4 combined as long as 1, subequal in length, laterally compressed, 3-4 projecting on inner margin; 5-10 elongate, subequal in length; 11 long oval; 1-4 punctate with scattered setae; 5-11 setose. Pronotum: transverse, slightly narrower apically than basally; lateral margin straight then rounding to anterior angle; anterior angle rounded, not projecting; posterior angle angulate; anterior margin weakly emarginate behind head; disc flattened; smooth; surface finely, irregularly punctate; basal impression absent; pronotal length 1.4-1.7 mm; pronotal width 1.9-2.1 mm. Scutellum: elongate pentagonal; impunctate. Elytron: lateral margin straight, smooth, rounding to apex; apex rounded; sutural angle angulate, without tooth; humerus rounded, not produced; slightly constricted behind humerus; finely punctate-striate, rows becoming obsolete after middle, apical punctures confused; elytral length 6.1-6.7 mm; elytral width 2.6-2.8 mm. Venter: inner margin of epipleuron ciliate; pro-, meso-, and metasterna impunctate; abdominal sterna punctate, each puncture with pale seta; suture between abdominal sterna 1 and 2 complete; last sternite with apical margin truncate, weakly emarginate in male, bisinuate in female. Leg: thickened, flattened; punctate; tibia with fringe of setae on inner margin of apex. Total length: 8.6-10.5 mm.

Diagnosis.

This species is most similar to Cephaloleia kressi sp. n. It can be distinguished by the following combination of characters: the elytra without a declivity from puncture row 7, the elytral punctation is obsolete after the middle, by the vertex of the head without a medial sulcus, by the angulate sutural angle of the elytra, and by the impunctate pro-, meso-, and metasterna.

Host plant.

Adults have been collected on Heliconia sp. ( Heliconiaceae ) ( Staines 1996).
