Description.

Elongate; subparallel; subdepressed; reddish-yellow, head and antennae darker. Head: vertex finely punctate, medial sulcus absent; frons not projecting; slightly depressed between eyes. Antenna: ½ body length; slender; antennomeres 1-4 elongate; 1 subclavate; 2 shorter than 1, thicker than 3, subequal in length to 4; 3 longest, 2 × longer than 2; 5-10 transverse, subequal in length; 11 2 × length of 10, broadly rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight and diverging to beyond middle then rounding to anterior angle, slightly canaliculate; anterior angle obtuse, slightly projecting; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface with disc sparsely punctate, larger punctures laterally; transverse medial basal impression present; pronotal length 1.1-1.5 mm; pronotal width 1.9-2.1 mm. Scutellum: broadly pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; constricted behind humerus; finely punctate-striate, punctures nearly obsolete at apex; with ill-defined longitudinal sulcus behind humerus; elytral length 4.0-4.4 mm; elytral width 2.1-2.3 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin quadrate-emarginate and sinuate medially in male, truncate in female. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 5.3-5.8 mm.

Diagnosis.

This species is similar to Cephaloleia chimboana and Cephaloleia lojaensis . It can be distinguished by the pronotum without a transverse basal impression and by the distinct elytral punctures which becomes obsolete apically.

Distribution.

Brazil (Amazonas, Bahia, Rondonia), Peru.
