Description.

Elongate; subparallel; subdepressed; shining; yellow; antennae yellowish brown; vertex of head with oval black macula, pronotum with black broad longitudinal band, which begins at the apex and widens posteriorly, scutellum black, and basal ⅓ of elytra with black oval macula, elytra slightly darkened beneath humerus; pro-, meso-, and metasternum yellowish medially, dark laterally; sternites diffuse black. Head: vertex extremely finely punctate, with medial sulcus and callus between the antennal bases; frons not projecting; not depressed between eyes. Antenna: reaches to base of elytra; slender; antennomeres with whitish setae; 1 longest, incrassate; 2-6 cylindrical, elongate, decreasing in length; 7-10 transverse, subequal in length, each shorter than 6; 11 2 × length of 10, rounded at apex; 1-3 punctate with scattered setae; 3-11 setose. Pronotum: transverse, nearly as wide as base of elytra; lateral margin straight then rounding to anterior angle, margined; anterior angle rounded, produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface with scattered strong and irregular punctures; basal impression absent; pronotal length 1.3-1.5 mm; pronotal width 1.7-1.9 mm. Scutellum: pentagonal, impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, rows converge and unite apically; interspaces not raised; each puncture darkened; elytral length 4.7-4.9 mm; elytral width 2.0-2.2 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 emarginate medially in male, rounded in female. Leg: slender; sparsely punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 6.4-6.7 mm.

Diagnosis.

This species is similar to Cephaloleia fryella and Cephaloleia lydiae . It can be distinguished by the longitudinal black vitta on the pronotum which extends from the base to the apex.
