Cephalolia depressa Baly 1858: 60. Gemminger and Harold 1876: 3601 (catalog); Donckier 1899: 548 (catalog); Weise 1911a: 7 (catalog), 1911b: 11 (catalog).

Cephaloleia depressa Baly. Maulik 1924: 246 (noted); Uhmann 1948a: 220 (noted), 1957b: 17 (catalog); Mariau 1999: 233 (noted), 2001: 132 (noted); Staines and Staines 1999: 523 (Baly species list).

Description.

Small; elongate; flattened; black, lateral margins of pronotum paler; venter black; tarsi piceous. Head: vertex punctate, with medial carina; frons not projecting; depressed between eyes. Antenna: ½ body length; slender; antennomere 1 slightly incrassate, elongate, longer than 2, subequal in length to 3; 2 elongate, cylindrical; 3 elongate, slender; 4-10 elongate, slightly decreasing in length, each shorter than 3; 11 2 × length of 10, pointed at apex; 1-2 punctate; 3-11 setose. Pronotum: quadrate; lateral margin arcuate, canaliculate, serrulate; anterior angle pointed; posterior angle acute; anterior margin emarginate behind head; disc slightly convex; surface densely coarsely punctate; basal impression absent; pronotal length 0.6-0.9 mm; pronotal width 1.1-1.5 mm. Scutellum: broadly triangular; alutaceous. Elytron: lateral and apical margins smooth; lateral margin straight, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; punctures moderately impressed; pygidium coarsely punctate, obtusely rounded at apex; elytral length 2.4-2.8 mm; elytral width 1.1-1.5 mm. Venter: pro-, meso-, and metasterna sparsely punctate; abdominal sterna sparsely punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin deeply sinuate in male, emarginate medially in female. Leg: slender; punctate; femur and tibia with pale seta in each puncture; tibia with fringe of setae on inner margin of apex. Total length: 3.5-3.9 mm.

Diagnosis.

This species is similar to Cephaloleia donckieri , Cephaloleia elaeidis , Cephaloleia tarsata , and Cephaloleia zikani . It can be distinguished by the vertex of the head without a medial fovea, by the serrulate lateral margins of the pronotum, by the smooth apical margins of the elytra, and by antennomere 2 being obconic.

Host plant.

Elaeis guineensis Jacq. ( Arecaceae ) ( Mariau 2001).

Distribution.

Brazil (Bahia, Matto Grosso, Pará), Ecuador.
