- Cephaloleia formosus Staines 1996[1]: 34.
Description
Narrow, elongate, subparallel, flattened; black with yellow elytral vitta; leg with tarsi yellow, rest black. Head: vertex densely, deeply punctate, medial sulcus absent; frons not projecting; not depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomere 1 elongate, subequal in length to 3; 2 elongate, shorter than 1 or 3; 4–10 transverse, subequal in length; 11 2× length of 10, rounded at apex; 1–2 punctate with scattered setae; 3–11 setose. Pronotum: transverse; lateral margin evenly arcuate from base to anterior angle, serrulate, slightly canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin sinuate behind head; disc subconvex; surface with large, shallow punctures laterally, very few punctures on disc; basal impression absent; pronotal length 0.9–1.0 mm; pronotal width 1.1–1.3 mm. Scutellum: pentagonal, alutaceous. Elytron: lateral margin straight, smooth, margined; apex truncate; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; puncture rows shallow, almost obsolete laterally and apically; elytral length 3.4–3.8 mm; elytral width 1.3–1.6 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin emarginate medially in male, truncate in female. Leg: slender; femur and tibia punctate; tibia with fringe of setae on inner margin of apex. Total length: 4.4–5.3 mm.
Diagnosis
This species is similar to Cephaloleia gracilis and Cephaloleia vagelineata. It can be distinguished by the serrulate lateral margins of the pronotum, by the rounded anterior angles of the pronotum, and by the suture between abdominal sterna 1 and 2 being obsolete medially.
Host plant
Adults have been collected on Elaeis guineensis Jacq. (Areaceae) (Staines 1996[1]).
Distribution
Belize, Colombia, Panama.
