Description.

Elongate; subparallel; depressed; head (except yellow frons), antennae, and scutellum black; pronotum yellow with triangular black macula behind head on anterior margin; elytra black with narrow yellow vittae which becomes obsolete on apical 1/5; venter with prosternum yellow, meso- and metasterna yellow medially, black laterally, abdominal sternite 1 entirely black, 2-5 yellow; legs with femur yellow with apex darker, coxae, tibiae, and tarsi darker. Head: vertex punctate, faint medial sulcus present; eyes convex, finely faceted; frons longitudinally strigose-punctate, not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, elongate, compressed; 2 subglobose, short; 3 elongate, 2 × length of 2, triangular with projecting angle; 4-10 transverse; 4 ¾ length of 3; 5 shorter than 4; 6-10 subequal in length, each shorter than 5; 11 more than 2 × length of 2, pointed at apex; 1-2 punctate with scattered setae; 3-5 sparsely setose; 6-11 setose. Pronotum: quadrate; lateral margin straight then rounding to anterior angle, margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc flattened; surface with scattered large punctures laterally, impunctate medially; basal impression absent; pronotal length 1.15-1.27 mm; pronotal width 1.38-1.81 mm. Scutellum: elongate, acutely triangular; micropunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex obtusely rounded; sutural angle without tooth; humerus rounded, not produced; constricted behind humerus; declivity beginning just behind humerus at puncture row 7 without faint carina; shallowly punctate-striate, rows converge and unite apically; elytral length 4.6-5.1 mm; elytral width 2.0-2.3 mm. Venter: prosternum impunctate; 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 truncate in male, broadly concave in female. Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.9-6.7 mm.

Diagnosis.

This species is similar to Cephaloleia bella , Cephaloleia championi , and Cephaloleia luctuosa . It can be distinguished by the vertex of the head being depressed between the eyes, by the pronotum being punctate laterally, and by antennomere 2 being triangular.

Host plant.
