- Cephaloleia facetus Staines 1996[1]: 33.
Description
Small; elongate; flattened; head, pronotum, venter, and legs reddish-brown; elytra, antennae, and eyes dark. Head: vertex sparsely punctate, with faint medial carina; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1–2 short, cylindrical, subequal in length; 3 elongate, cylindrical, as long as 1 and 2 combined; 4–10 transverse, subequal in length, each longer than 2; 11 2× length of 10, rounded at apex; 1–2 punctate with scattered setae; 3–11 setose. Pronotum: subquadrate; lateral margin curved, margined; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; basal margin broadly, shallowly emarginate laterally; disc flattened, impunctate with faint longitudinal medial sulcus; surface punctate laterally; basal impression absent; pronotal length 0.7 mm; pronotal width 0.7–0.9 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin sinuate, smooth, margined; apex rounded; sutural angle without tooth; humerus angulate, slightly produced; slightly constricted behind humerus; basal margin produced, which fits into pronotal notch; shallowly punctate-striate, rows converge and unite at apex; elytral length 2.4–2.7 mm; elytral width 1.1–1.4 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna sparsely punctate, each puncture with seta; suture between sterna 1 and 2 complete. Leg: slender; sparsely punctate; tibia with fringe of setae on inner margin of apex. Total length: 3.3–3.7 mm.
Diagnosis
This species is similar to Cephaloleia amblys. It can be distinguished by the pronotum being paler than the elytra and by antennomeres 1 and 2 being subequal in length.
Host plant
Adults have been collected on unidentified palm (Areaceae) (Staines 1996[1]).
Distribution
Panama.
