Description.

Elongate; subdepressed; shining; black; palps and basal half of elytra and epipleuron yellowish-brown; male with venter black; female with prosternum and base of abdomen reddish-yellow; antennae dark. Head: vertex finely, densely punctate, faint medial carina present; frons not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomeres oblong; 1 elongate; 2 shorter, oval; 3 longer than 2, elongate; 4-5 subequal in length, each shorter than 3; 6-10 each longer than 5; 11 longer than 10, pointed at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, slightly canaliculate; anterior angle rounded, produced; posterior angle acute; anterior margin straight; disc subconvex; surface punctate except medial longitudinal line on disc; basal impression absent; pronotal length 1.0-1.3 mm; pronotal width 1.3-1.5 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, finely margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, punctures becoming obsolete apically; elytral length 4.2-4.6 mm; elytral width 1.9-2.1 mm. Venter: pro-, 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 sinuate medially in male; truncate in female. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 5.5-6.0 mm.

Diagnosis.

This is a bicolored species with the apical section of the elytra darker. It is most similar to Cephaloleia apicenotata and Cephaloleia bicoloriceps . It can be distinguished by the straight lateral margin of the pronotum, by antennomere 2 being oval, and by the elytral punctures becoming obsolete apically.
