Description.

Elongate; subparallel; subdepressed; shining; dark yellowish, antennae (except apex of antennomere 11 yellowish) and apical ⅔ elytra black, eyes dark. Head: vertex finely punctate, medial sulcus present; carina present between antennal bases; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; robust; antennomere 1 incrassate, subclavate, elongate; 2-3 elongate, cylindrical, subequal in length, each about ¾ length 1; 4-10 transverse, subequal in length, each ¾ length of 3; 11 2 × length 10, broadly rounded at apex; 1-2 punctate, with seta in each puncture; 3-11 setose. Pronotum: subquadrate; lateral margin straight then rounding to anterior angle, canaliculate; anterior angle obtusely rounded, slightly produced; posterior angle acute; anterior margin weakly emarginate behind head; disc subconvex; depressed laterally near base; surface with disc finely, sparsely punctate, punctures more dense and deeper laterally; pronotal length 1.5-1.9 mm; pronotal width 2.0-2.4 mm. Scutellum: broadly pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; disc moderately convex; moderately punctate-striate, punctures becoming finer apically, rounds converge and unite apically; elytral length 5.2-5.9 mm; elytral width 2.5-2.9 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin broadly emarginate, slightly protruding medially in female, broadly emarginate and sinuate laterally in male. Leg: slender; sparsely punctate; tibia with fringe of setae on inner margin of apex. Total length: 7.0-7.9 mm.

Diagnosis.

This species is similar to Cephaloleia basalis . It can be distinguished by the elytral puncture rows converging and uniting apically and by antennomere 2 being subequal in length to 3.
