Description.

Elongate; subparallel; subdepressed; reddish-brown, eyes and antennomeres 4-11 darker. Head: vertex impunctate, medial sulcus present; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 elongate, thickened; 2 transverse; 3 elongate, ¾ length of 1; 4-10 transverse, subequal in length; 11 2 × length of 10, pointed at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse, lateral margin straight for basal ¾ then rounding to anterior angle, margined; anterior angle rounded, produced; posterior angle angulate; anterior margin emarginate behind head; disc subconvex; surface sparsely and irregu larly punctate; basal impression absent; pronotal length 1.1-1.3 mm; pronotal width 1.7-1.9 mm. Scutellum: pentagonal, impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not projecting; slightly constricted behind humerus; shallowly punctate-striate, humerus almost impunctate; puncture rows confused at apex; elytral length 4.1-4.9 mm; elytral width 2.1-2.4 mm. Venter: prosternum impunctate medially, rugose laterally; meso- and metasterna entirely impunctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin weakly rounded in male; strongly rounded in female. Leg: slender; punctate; femur with pale seta in each puncture; tibia dentate at apex, fringe of setae at apex. Total length: 5.6-6.4 mm.

Diagnosis.

This species is similar to Cephaloleia castanea , Cephaloleia delectabilis , and Cephaloleia opaca . It can be distinguished by the impunctate vertex of the head which has a medial sulcus, by antennomere 3 being longer than 1, and by the elytral punctures being confused apically.

Host plant.

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