Description.

Elongate; subparallel; subdepressed; shining; reddish-yellow; apical three antennomeres and eyes darkened. Head: vertex finely, distinctly punctate, medial carina present; frons not projecting; depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, elongate, obliquely truncate at apex; 2 ½ length of 1, cylindrical; 3 longer than 2; 4-10 transverse, subequal in length, each shorter than 3; 11 2 × length of 10, pointed at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, canaliculate; anterior angle rounded, produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface distinctly, finely punctate with longitudinal area medially impunctate; slight transverse basal impression present medially; pronotal length 1.2-1.4 mm; pronotal width 1.8-2.0 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; weakly punctate-striate, punctures large, confused apically; elytral length 3.3-4.2 mm; elytral width 2.0-2.2 mm. Venter: pro- and mesosterna impunctate medially, punctate laterally; metasternum punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete. Leg: robust; punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.0-6.0 mm.

Diagnosis.

This species is similar to Cephaloleia striata , Cephaloleia subdepressa , Cephaloleia truncatipennis , and Cephaloleia unctula . It can be distinguished by the transverse basal impression on the pronotum and by antennomere 1 being longer than 2.
