Description.

Small; elongate; ovate; subdepressed; shining; reddish-yellow; antennae, except basal antennomere, black; elytra bluish except lateral margin or totally reddish-yellow. Head: vertex impunctate, medial carina absent, eyes not strongly convex; frons small, not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-5 elongate, cylindrical; 1 2 × length of 2; 3-5 subequal in length, each longer than 2; 6-10 transverse, subequal in length, each shorter than 5; 11 longest, pointed at apex; 1-2 impunctate; 3-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, moderately margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface finely, sparsely punctate; basal impression absent; pronotal length 0.6-0.8 mm; pronotal length 1.0-1.2 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; flattened along suture; shallowly punctate-striate, punctures confused near apex; elytral length 2.3-2.6 mm; elytral width 1.2-1.4 mm. Venter: pro-, meso-, and metasterna impunctate; abdominal sterna sparsely punctate, each puncture with white seta; suture between sterna 1 and 2 complete; last sternite with apical margin strongly emarginate in male, rounded in female. Leg: slender; impunctate; tibia with fringe of setae on inner margin of apex. Total length: 3.0-3.5 mm.

Diagnosis.

This species has two color forms. The bicolored form is similar to Cephaloleia abdominalis , Cephaloleia amazona , Cephaloleia princeps , Cephaloleia susanae sp. n., and Cephaloleia teutonica . It can be distinguished by the smaller size, by the lateral margin of the pronotum being straight, and by the vertex of the head with a medial fovea, carina or sulcus.

The pale form is similar to Cephaloleia crenulata sp. n. It can be distinguished by the smooth lateral margins of the pronotum, by the impunctate vertex of the head, and by antennomere 1 being twice the length of 2.

Distribution.

Brazil (Rondonia), Colombia.
