Description.

Elongate; subparallel; subdepressed; pale yellowish brown, the apical four or five antennomeres darkened, apex of antennomere 11 pale, elytral punctures dark. Head: vertex very finely punctate, impunctate between the eyes, medial sulcus absent; frons not projecting; not depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomere 1 elongate; 2 elongate, a little shorter than 1; 3 subequal in length to 1; 4-5 elongate, subequal in length, each nearly as long as 3; 6-10 slightly transverse, slightly different in shape from each other, subequal in length, each shorter than 5; 11 elongate, 2 × length of 10, bluntly rounded at the apex; 1-4 impunctate; 5-11 with setae. Pronotum: transverse; lateral margin straight and divergent for basal ⅔ then rounded and convergent, canaliculate; anterior angle broadly rounded; posterior angle acute; anterior margin emarginate behind head; disc flattened; surface with scattered, very shallow punctures, disc nearly impunctate; basal impression absent; pronotal length 1.2-1.4 mm; pronotal width 1.7-1.9 mm. Scutellum: rounded-pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus slightly prominent; slightly constricted behind humerus; finely punctate-striate, punctures mostly confluent, rows dark, clearly visible for entire length; elytral length 4.3-4.7 mm; elytral width 2.1-2.4 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin deeply and broadly emarginate in male; last sternite with apical margin rounded in female. Leg: slender; punctate; femur robust; femur and tibia with pale seta in each puncture; tibia with fringe of setae on inner margin of apex. Total length: 6.3-6.8 mm.

Diagnosis.

This species is similar to Cephaloleia lojaensis and Cephaloleia nigriceps . It can be distinguished by the tranverse basal impression on the pronotum and by the confluent elytral punctures.
