Description.

Large; elongate; subparallel; subdepressed; reddish-brown, eyes darker; venter with meso- and metasterna paler medially, darker laterally. Head: vertex sparsely punctate, medial sulcus absent; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; robust; antennomere 1 incrassate, as long as 2-4 combined; 2-3 transverse, each with projection on inner apex; 4-10 transverse, decreasing in length; 11 2 × length of 10, pointed at apex; 1-4 punctate with scattered setae; 5-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin weakly emarginate behind head; disc flattened; surface sparsely punctate; basal impression absent; pronotal length 1.3-1.6 mm; pronotal width 1.9-2.0 mm. Scutellum: pentagonal; alutaceous. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, slightly produced; slightly constricted behind humerus; shallowly punctate-striate, humerus virtually impunctate; rows converge and unite near apex; declivity beginning just behind humerus along puncture row 7 with weak carina; elytral length 5.0-5.7 mm; elytral width 2.3-2.7 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially. Leg: robust; impunctate; tibia with fringe of setae on inner margin of apex. Total length: 6.6-7.8 mm.

Diagnosis.

This species is similar to Cephaloleia congener . It can be distinguished by the sparsely punctate pronotum, by the suture between abdominal sterna 1 and 2 being obsolete medially, and by antennomere 1 being subequal in length to 2 to 4 combined.

Distribution.
