Description.

Elongate; subdepressed; shining; reddish-brown; eyes and antennomeres 6-11 darker; legs yellowish. Head: vertex punctate, medial carina present; frons impunctate, not projecting; depressed between eyes. Antenna: longer than head and pronotum combined; robust; antennomere 1 large, slightly incrassate; 2 elongate, shorter than 1, subequal in length to 3; 3-10 decreasing in length; 11 bluntly pointed at apex; 1-2 punctate; 3-11 setose. Pronotum: transverse; lateral margin straight and diverging for basal ¾ then rounding to anterior angle, slightly laminate; anterior angle with rounded tooth, projecting; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface sparsely, coarsely punctate, less punctate on disc; slight transverse basal impression present medially; pronotal length 1.4-1.7 mm; pronotal width 2.0-2.4 mm. Scutellum: triangular; impunctate. Elytron: lateral margin slightly expanding apically, smooth, margined; apex rounded, apical margin smooth; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, punctures confused apically; striae on apical half slightly sulcate; elytral length 5.4-5.9 mm; elytral width 2.9-3.0 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between abdominal sterna 1 and 2 complete; female with apical margin of last sternite bisinuate. Leg: slender; punctate; femur and tibia with seta in each puncture; tibia with fringe of setae at apex. Total length: 7.2-7.6 mm.

Diagnosis.

This species is most similar to Cephaloleia bucki . It can be distinguished by the medial carina on the vertex of the head and by the elytra being slightly costate apically.

Distribution.
