Description.

Elongate; slightly expanded apically; subdepressed; reddish-brown; antennae (except basal 3 antennomeres) and eyes darker. Head: vertex impunctate, with strong medial carina; frons impunctate, not projecting; depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomere 1 robust, subclavate, longest; 2 transverse, ⅓ length of 1; 3 elongate, cylindrical, longer than 2; 4-10 elongate, cylindrical, 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 and converging for basal ¾ then rounding to anterior angle, canaliculate, slightly laminate; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface sparsely, coarsely punctate, punctures more dense basally and laterally; transverse basal impression present medially; pronotal length 1.6-1.7 mm; pronotal width 2.0-2.1 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin slightly expanding apically, smooth, margined; apex subtruncate; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; disc flattened; shallowly punctate-striate, punctures obsolete apically; elytral width 5.0-5.1 mm; elytral width 2.5-2.6 mm. Venter: prosternum punctate medially, impunctate laterally; meso- and metasterna impunctate; abdominal sterna punctate, each puncture with pale seta; suture between abdominal sterna 1 and 2 complete; last sternite with apical margin obtuse-truncate in female. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 6.7-6.8 mm.

Diagnosis.

This species is similar to Cephaloleia interstitialis, Cephaloleia striata, Cephaloleia subdepressa, and Cephaloleia unctula . It can be distinguished by the transverse basal impression on the pronotum and by antennomere 1 being longer than 2 but shorter than 2 and 3 combined.
