Description.

Narrowly elongate; subdepressed; shining; head, antennae (except antennomeres 1-4 yellowish), and scutellum black; pronotum yellow; elytra black, with yellow lateral margin and broad yellow subsutural vitta which reaches to beyond middle and connects to lateral margin; venter black with lateral margin of abdomen piceous; coxae and legs yellow, darkened at tibio-tarsal joint. Head: vertex with small fovea, faint medial carina present; front and vertex finely punctate; frons not projecting; slightly depressed between eyes Antenna: reaches to humerus; robust; antennomere 1 clavate, slightly incrassate, longer than 2; 2 transverse, ½ length of 1; 3 elongate, cylindrical, ¾ length of 1; 4-10 transverse, subequal in length; 11 2 × length of 10, subequal in length to 2, broadly rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin slightly sinuate, narrowed basally then rounding to anterior angle, canaliculate; anterior angle obtuse, produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface deeply, coarsely punctate, more dense laterally; basal impression absent; pronotal length 1.2-1.4 mm; pronotal width 1.5-1.7 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin slightly expanding apically, smooth, slightly margined; apex obtusely rounded; weakly emarginate at suture, sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; flattened; moderately punctate-striate, rows converge and unite apically; lateral interspaces sulcate; pygidium obtuse; elytral length 4.0-4.3 mm; elytral width 1.9-2.1 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin broadly emarginate, sinuate medially in male, sinuate in female. Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.1-5.8 mm.

Diagnosis.

This species is similar to Cephaloleia vittipennis . It can be distinguished by the medial fovea on the vertex of the head and by the basal impression on the pronotum.
