Small; elongate; subparallel; subdepressed; head and antennae yellowish-brown; pronotum pale yellow with broad black longitudinal vitta from anterior margin to basal margin; scutellum dark; elytra pale yellow with black cordate macula at base along suture, with small black macula at humerus, with black W-shaped vitta on apical ½, and black macula on apex near sutural angle; venter brownish-yellow; legs pale yellow. Head: vertex coarsely, densely punctate, me dial carina present; frons punctate, not projecting; keel present between antennal bases; depressed between eyes. Antenna: reaches to humerus; robust; antennomere 1 subclavate, elongate; 2 elongate, ¾ length of 1; 3-4 elongate, subequal in length, each ¾ length of 2; 5-10 transverse, subequal in length, each ¾ length of 4; 11 2 × length of 10, broadly rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin sinuate basally then rounding to anterior angle, narrowly margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface sparsely punctate; basal impression absent; pronotal length 1.0 mm; pronotal width 1.2-1.4 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; declivity beginning just behind humerus along puncture row 7 with weak carina; moderately punctate-striate, rows converge and unite apically; elytral length 3.0-3.1 mm; elytral width 1.5-1.8 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin emarginate medially in male, truncate in female.

Etymology.

Named for Carol C. Horvitz in recognition of her many contributions to the understanding of the ecology and evolution of Zingiberales and their interactions with pollinators, seed dispersers, and insect herbivores and her collegiality over the years. Also in recognition of her mentorship to new generations of resesearchers. The name is feminine.

Diagnosis.

This species is similar to Cephaloleia antennata . It can be distinguished by the vertex of the head having a medial carina, by the pronotum lacking an oblique impression, and by the smaller size.

Distribution.

French Guiana.
