Description.

Large; elongate; subparallel; subdepressed; shining; head, pronotum, scutellum, venter, and legs reddish; eyes and antennae black, elytra greenish-black. Head: vertex finely punctate, with small fovea; frons not projecting; slightly depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomere 1 obovate, incrassate, longer than 2; 2 transverse, triangular in male; 3 elongate, triangular in male, subequal to 1; 4-5 elongate, subequal in length, each shorter than 3; 4 triangular in male; 6-10 transverse, subequal in length; 11 2 × length 10, broadly rounded at apex; 1-5 punctate, glabrous; 6-11 setose. Pronotum: subquadrate; lateral margin dilated, straight for basal ¾, then rounding to anterior angle, canaliculate; anterior angle acute, slightly produced; posterior angle acute; anterior margin curved anteriorly; disc subconvex; surface deeply punctate, more dense laterally, sparse on disc; basal impression absent; pronotal length 2.3-2.7 mm; pronotal width 3.2-3.6 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded, apical margin thickened; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; faint carina present behind humerus along puncture row 7; disc flattened along suture; finely punctate-striate, rows converge and unite apically; pygidium finely punctate, rounded at apex; elytral length 8.4-9.0 mm; elytral width 4.0-4.4 mm. Venter: pro-, meso-, and metasterna impunctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin emarginate medially in male, sinuate in female. Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 11.0-11.7 mm.

Diagnosis.

This species is similar to Cephaloleia abdominalis , Cephaloleia amazona , Cephaloleia steinhauseni , Cephaloleia susanae sp. n., and Cephaloleia teutonica . It can be distinguished by the vertex of the head having a medial fovea and by the faint carina behind the humerus along puncture row 7 of the elytra.
