Description.

Small; elongate; subparallel; subconvex; reddish-brown; eyes darker. Head: vertex punctate, with medial carina; frons impunctate, not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 elongate, longer than 2 and 3 combined, slightly incrassate, apical margin produced with horn-like projection; 2-6 elongate, cylindrical; 2 longer than 3; 3 longer than 4; 4-6 elongate, subequal in length; 7-10 transverse, subequal in length, each shorter than 6; 11 pointed at apex; 1-6 punctate with scattered setae; 7-11 setose. Pronotum: transverse; lateral margin sinuate for basal ¾ then rounding to anterior angle, canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc flattened; surface densely, coarsely punctate; basal impression absent; pronotal length 1.0-1.2 mm; pronotal width 1.2-1.4 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; shallowly punctate-striate, punctures large, slightly confused api cally; elytral length 3.4-3.7 mm; elytral width 1.5-1.7 mm. Venter: pro-, meso-, and metasterna impunctate; abdominal sterna impunctate, glabrous; suture between sterna 1 and 2 complete. Leg: slender; impunctate; tibia with fringe of setae on inner margin of apex. Total length: 4.5-5.0 mm.

Diagnosis.

This species is similar to Cephaloleia interstitialis , Cephaloleia striata , Cephaloleia subdepressa , and Cephaloleia truncatipennis . It can be distinguished by the lack of a transverse basal impression on the prontum and by antennomere 1 being longer than 2 and 3 combined.
