Description.

Oblong-oval; subconvex; head, antennae, pronotum, and scutellum dark brown; elytra yellowish with dark brown sutural vitta starting at basal margin, dilated just past scutellum, then gradually narrows to just beyond midline, then only suture darkened, and a brown pointed, ovoid, elongate macula on apical ⅓; venter with pros ternum brown, meso- and metasterna brown medially and black laterally, abdominal sterna dark medially and pale laterally; legs yellow. Head: vertex densely punctate, each puncture with short pale seta, medial sulcus absent; frons not projecting; keel between antennal bases; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 longer than 2, thickened; 2-3 transverse, subequal in length; 4-10 transverse, decreasing in length; 11 2 × length of 10, rounded at apex; 1-4 punctate with scattered setae; 5-11 setose. Pronotum: transverse; lateral margin straight and convergent from base to apex, canaliculate, especially near apex; anterior angle obtuse, produced; posterior angle acute; anterior margin emarginate behind head; disc convex, surface densely and shallowly punctate; basal impression absent; pronotal length 0.9-1.2 mm; pronotal width 1.3-1.7 mm. Scutellum: pentagonal; micropunctate. Elytron: lateral margin straight, smooth, slightly laminate; apex obtusely rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; punctures large, shallow; humerus nearly impunctate; elytral length 4.0-4.2 mm; elytral width 2.1-2.3 mm. Venter: prosternum impunctate; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna sparsely punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially. Leg: slender; glabrous, impunctate; tibia with fringe of setae on inner margin of apex. Total length: 5.1-5.4 mm.

Diagnosis.

This species is similar to Cephaloleia balyi , Cephaloleia deficiens , Cephaloleia dorsalis , Cephaloleia linkei , and Cephaloleia suturalis . It can be distinguished by the black pronotum and by antennomere 1 being longer than 3.

Distribution.
