Description
Small; elongate; subparallel; subconvex; reddish-brown; eyes and antennomeres 7–11 darker. Head: vertex sparsely punctate, medial sulcus absent; small carina present between bases of antennae; frons impunctate, not projecting; slightly depressed between eyes. Antenna: ½ body length; slender; antennomere 1 short, transverse; 2–10 cylindrical; 2 elongate, 2× length of 1; 3–4 elongate, subequal in length, each longer than 2; 5–6 elongate, subequal, each shorter than 3; 7–10 transverse, subequal, each shorter than 6; 11 2× length of 10, acutely pointed at apex; 1–6 punctate; 7–11 setose. Pronotum: transverse; lateral margin straight for basal ¾ then rounding to anterior angle, canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface sparsely, coarsely punctate, punctures more dense laterally; basal impression absent; pronotal length 0.9–1.1 mm; pronotal width 1.2–1.6 mm. Scutellum: triangular, impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; subconvex with disc flattened; moderately punctate-striate, punctures less impressed apically; elytral length 3.2–3.6 mm; elytral width 1.5–1.7 mm. Venter: pro-, meso-, and metasterna punctate, each puncture with pale seta; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin sinuate medially in male; in female emarginate medially. Leg: slender; punctate, each puncture with pale seta; femur robust; tibia with fringe of setae on inner margin of apex. Total length: 4.0–4.9 mm.
Diagnosis
This species is similar to Cephaloleia latipennis and Cephaloleia polita. It can be distinguished by the elytral puncture rows being regular to the apex and by antennomere 1 being transverse.
Host plant
According to label data, adults have been collected on an unidentified palm (Arecaceae).
Distribution
Brazil (São Paulo), Peru.
Type material examined
Syntype: Peru [handwritten label]/ Cephalolia dimidiaticornis Baly, Peru [blue handwritten label] (BMNH, 1).
Specimens examined
BRAZIL: São Paulo- no further data (USNM). Peru: no further data (BMNH). Loreto- Tambo Pirana on Río Cochiquinas, 1 July 1978 (USNM). Total: 3.
