Description.

Small; elongate-oval; flattened; reddish-brown with margins of pronotum and elytra paler; head and antennae dark, except basal antennomeres. Head: vertex densely punctate, medial carina present; frons impunctate, not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-3 cylindrical; 1-2 subequal in length; 3 longer than 1 or 2; 4 shorter than 3; 5-10 transverse, decreasing in length; 11 2 × length of 10, rounded at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight, slightly divergent at basal ½ then rounding to anterior angle, slightly canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin curved anteriorly; basal margin biangulate; disc subconvex; surface sparsely coarsely punctate, more so laterally; basal impression absent; pronotal length 0.5-0.7 mm; pronotal width 0.7-0.9 mm. Scutellum: triangular; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, rows converge and unite apically; elytral length 1.9-2.1 mm; elytral width 0.9-1.1 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 concave-emarginate medially in male, rounded entire in female. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 2.5-2.8 mm.

Diagnosis.

This species is similar to Cephaloleia interstitialis , Cephaloleia striata , Cephaloleia truncatipennis , and Cephaloleia unctula . It can be distinguished by the pronotum lacking a transverse basal impression and by antennomere 1 being subequal in length to 2.

Distribution.

Brazil (Minas Gerais).
