Description.

Small; subdepressed; shining; black; lateral margin of pronotum and elytra and tarsi brownish. Head: vertex finely, densely punctate, medial sulcus absent; frons not projecting; not depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomeres 1 and 2 subequal in length; 1 cylindrical; 2 subglobular; 3 2 × length of 2, cylindrical, elongate, more slender; 4 cylindrical, elongate, shorter than 3; 5-10 decreasing in length, becoming transverse; 11 2 × length of 10, acutely pointed at apex; 1-5 punctate with scattered setae; 6-11 setose. Pronotum: transverse; lateral margin rounded, smooth, margined; anterior angle rounded, produced; posterior angle acute; anterior margin curved posteriorly behind head; disc subconvex; disc with fine, irregular punctures, punctures larger, denser laterally; transverse basal impression present medially; pronotal length 0.4-0.5 mm; pronotal width 1.1-1.3 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apex obliquely rounded; sutural angle with small tooth; humerus rounded, not produced; slightly constricted behind humerus; finely punctate-striate, punctures obsolete at apex; elytral length 2.3-2.8 mm; elytral width 1.2-1.4 mm. Venter: prosternum rugose medially, punctate laterally; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with white seta; suture between sterna 1 and 2 complete; last sternite with apical margin emarginate in male. Leg: slender; punctate; femur and tibia with pale seta in each puncture; tibia with fringe of setae on inner margin of apex. Total length: 3.3-3.7 mm.

Diagnosis.

This species is similar to Cephaloleia coroicoana , Cephaloleia deplanata , Cephaloleia marantae , and Cephaloleia rufipes . It can be distinguished by the basal impression on the pronotum and by the elytral punctures being distinct basally but obsolete apically.

Distribution.
