Description.

Oblong-elongate; subdepressed; shining; head, antennae, pronotum (except lateral margins), scutellum, apical ½ of elytra, venter, and femora black; tibiae and tarsi paler; basal ½ elytra yellowish, some specimens have a black sutural vitta which narrows apically to the darker apical ½; elytra with lateral and apical (almost to sutural angle) margins pale. Head: vertex moderately punctate, medial sulcus absent; eye convex; frons not projecting; depressed between eyes. Antenna: reaches beyond humerus; slender; antennomere 1 elongate, not incrassate; 2 ½ length 1; 3-4 elongate, each subequal in length to 1; 5-10 transverse, decreasing in length, each shorter than 4; 11 longer than 10, pointed at apex; 1-6 punctate with scattered setae; 7-11 setose. Pronotum: quadrate; lateral margin straight for basal ½ then slightly rounding to anterior angle, canaliculate; anterior angle angulate, slightly produced; posterior angle acute; anterior margin straight; disc subconvex, with medial longitudinal impression, narrowing basally; surface sparsely, strongly punctate; pronotal length 1.2-1.4 mm; pronotal width 1.4-1.6 mm. Scutellum: pentagonal; punctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle with small tooth; humerus rounded, slightly produced; constricted behind humerus; finely punctate-striate; elytral length 3.9-4.2 mm; elytral width 2.0-2.2 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 emarginate medially in male, rounded, entire in female. Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.4-5.7 mm.

Diagnosis.

This is a bicolored species with the apical section of the elytra darker. It is most similar to Cephaloleia apicenotata and Cephaloleia bicolor . It can be distinguished by the straight lateral margins of the pronotum, by antennomere 2 being elongate, and by the elytral punctures being distinct apically.

Distribution.

Bolivia, Brazil, Colombia, Ecuador.
