Description.

Elongate; subparallel; subconvex; reddish-yellow; eyes and antennae (except antennomere 1) black. Head: vertex punctate, medial sulcus present; frons not projecting; not depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomere 1 slightly incrassate, elongate; 2 transverse, ½ length of 1; 3 elongate, slightly expanding apically, 2 × length of 2; 4-10 elongate, subequal in length, each slightly longer than 2; 11 2 × length of 10, pointed at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight for basal 4/5 then rounding to anterior angle, canaliculate; anterior angle obtuse, produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex, impunctate; surface finely punctate laterally; basal impression absent; pronotal length 1.2-1.4 mm; pronotal width 1.8-2.0 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, canaliculate; apex rounded, serrate; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; slightly flattened along suture; shallowly punctate-striate, rows converge and unite apically; elytral length 4.6-5.0 mm; elytral width 2.2-2.6 mm. Venter: pro-, 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 broadly emarginate, sinuate medially in male; broadly truncate-emarginate in female. Leg: slender; punctate; tibia with fringe of setae at apex. Total length: 5.6-6.8 mm.

Diagnosis.

This species is similar to Cephaloleia apicicornis , Cephaloleia corallina , Cephaloleia halli , and Cephaloleia ochra sp. n. It can be distinguished by the pronotum lacking a transverse basal impression and by antennomeres 2 to 11 being black.

Host plant.

According to the label data, adults have been collected feeding on Heliconia sp. ( Heliconiaceae ).

Distribution.

Brazil (Amazonas, Pará), French Guiana, Peru.
