Description.

Elongate; subdepressed; subparallel; yellowish; antennomeres 1-8 brownish, 9-11 darker; eyes dark. Head: vertex finely, irregularly punctate; with deep medial sulcus; frons not projecting; depressed between eyes. Antenna: ½ body length; slender; cylindrical; antennomere 1 robust, 1½ x length of 2; 2-4 subequal in length; 5-10 subequal in length, each shorter than 4; 11 rounded at apex, 2 × length of 10; 1-4 punctate with scattered setae; 5-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, canaliculate; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface with deep, round punctures, more dense laterally; basal impression absent; pronotal length 1.1-1.3 mm; pronotal width 1.5-1.7 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, slightly laminate; apex rounded; sutural angle without tooth; humerus rounded, not produced; constricted behind humerus; disc flattened; moderately punctate-striate, punctures less impressed apically; interspaces convex; elytral length 3.8-4.2; elytral width 2.1-2.4 mm. Venter: pro-, meso-, and metasterna impunctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin concave-emarginate in male, bisinuate in female. Leg: slender; sparsely punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.5-5.8 mm.

Diagnosis .

This is a unicolorous yellowish species. It is most similar to Cephaloleia corallina, Cephaloleia halli, Cephaloleia ochra sp. n., and Cephaloleia proxima . It can be distinguished from these species by the pronotum without a transverse basal impression, by the pale non-black antennae, and by the meso- and metasterna being impunctate.
