Description.

Elongate; subdepressed; slightly shining; dorsum metallic-blue, antennae black. Head: vertex coarsely punctate; carina present between antennal bases; frons not projecting; slightly depressed between eyes. Antenna: ½ length of body; scarcely thickened apically; slender; antennomere 1 slightly thickened; 2 ¾ length 1; 3 nearly 1½ length of 2; 4-6 decreasing in length, each shorter than 2; 7-10 transverse, subequal in length, each shorter than 6; 11 2 × length 10, acutely pointed at apex; 1-5 punctate, glabrous; 6-11 setose. Pronotum: transverse; lateral margin straight, slightly sinuate then rounded and convergent to anterior angle, canaliculate; anterior and posterior angles acute; anterior margin emarginate behind head; disc subconvex; surface coarsely punctate laterally, disc and anterior margin behind head nearly impunctate; basal impression absent; pronotal length 1.2 mm; pronotal width 2.0 mm. Scutellum: pentagonal; as wide as long; sharply pointed at apex; with two fovea apically; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus with ill-defined protuberance; slightly constricted behind humerus; disc subconvex; slightly flattened along suture; moderately punctate-striate, punctures larger laterally; elytral length 4.4 mm; elytral width 2.3 mm. Venter: prosternum impunctate medially, rugose laterally; meso- and metasterna punctate, each puncture with pale seta; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin bisinuate. Leg: slender; punctate; femur and tibia with pale seta in each puncture; femur robust; tibia with fringe of setae at apex. Total length: 6.1 mm.

Diagnosis.

This species is similar to Cephaloleia dilatata and Cephaloleia diplothemium . It can be distinguished by the cylindrical antennomere 1 which is shorter than 3, by the elytral punctures being larger laterally, and by the prosternum being rugose laterally.
