Cephalolia antennata Waterhouse. Donckier 1899: 548 (catalog); Weise 1911a: 7 (catalog), 1911b: 11 (catalog).

Description.

Elongate; subparallel; convex; reddish-yellow; antennomeres 1-7, medial line of pronotum, scutellum, and elytral suture and humeri darker, head with blackish band on vertex, antennomeres 8-11 yellow; venter reddish-yellow medially, black laterally; legs yellow with femorotibial joint darkened. Head: eye large, prominent; vertex sparsely, irregularly punctate, medial sulcus absent; frons not projecting; depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, robust; 2 transverse, less than ½ length of 1; 3 subequal in length to 1, cylindrical; 4-10 decreasing in length, each shorter than 3; 11 2 × length of 10, broadly rounded at apex; 1-8 punctate; 9-11 setose. Pronotum: slightly longer than wide; lateral margin straight, rounding to anterior angle, narrowly margined; anterior angle obtusely rounded; posterior angle acute; anterior margin straight; disc subconvex; surface densely, strongly punctate; with oblique impression on each side reaching basal margin medially; pronotal length 1.4-1.7 mm; pronotal width 1.5-1.7 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin smooth, narrowly margined, slightly expanded apically; apex rounded, smooth; sutural angle without tooth; humerus slightly angulate, produced; slightly constricted behind humerus; strongly closely punctate-striate; elytral length 4.9-5.1 mm; elytral width 2.1-2.3 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. Leg: punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 6.5-7.1 mm.

Diagnosis.

This species is most similar to Cephaloleia horvitzae sp. n. It can be distinguished by the vertex of the head without a medial carina, by the pronotum having an oblique impression laterally, and by the larger size.

Distribution.

Brazil (Amazonas), Ecuador, Peru.
