Description.

Elongate, subparallel, subconvex; narrow; shining; black, with the basal ⅓ of elytra and elytral margin reddish-yellow; pronotal margin weakly reddish; venter with prosternum medially and mesosternum basally brownish-yellow; leg with tarsi and apex of the protibiae dark chestnut, almost black; tibio-femoral joint reddish chestnut. Head: vertex finely, sparsely punctate, with faint medial carina; eyes not strongly convex; slight keel present between antennal bases; frons not projecting; slightly depressed between eyes. Antenna: less than head and pronotum combined; slender; antennomere 1-2 subglobose, thick; 2 ¾ length of 1; 3 cylindrical, elongate, as long as 1 and 2 combined, longest; 4-10 transverse, subequal in length; 11 2 × length of 10, bluntly pointed at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: quadrate; lateral margin straight then rounding to anterior angle, narrowly margined; anterior angle rounded, not produced; posterior angle acute; anterior margin weakly emarginate behind head; disc subconvex; surface finely, densely punctate with some larger punctures laterally and basally and medial line impunctate; basal impression absent; pronotal length 1.2-1.6 mm; pronotal width 1.3-1.8 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded, slightly serrate; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, punctation more pronounced laterally, rows converge and unite apically; scutellar row long; elytral length 4.0-4.7 mm; elytral width: 1.8-2.2 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin broadly rounded in male, truncate in female. Leg: slender; punctate, each puncture with pale seta; tibia flattened, with fringe of setae on inner margin of apex. Total length: 5.0-6.5 mm.

Diagnosis.

This species is similar to Cephaloleia humeralis . It can be distinguished by antennomere 2 being subglobose and by the pronotum lacking a medial basal impression.

Host plant.

Canna sp. ( Monrós and Viana 1947), Cephaloleia denudata Roscoe ( Bondar 1931 b); Cephaloleia glauca L. ( Bruch 1937) ( Cannaceae ); Saccharum officinarum L. ( Maulik 1929); Panicum grumosum Nees ( Monrós and Viana 1947) ( Poaceae ).
