Description.

Small, almost rectangular in outline, depressed; reddish-brown; antennomeres 1-5 reddish, 6-10 black, 11 reddish. Head: vertex finely punctate; eyes dark; frons projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-2 elongate, subequal in length; 3 not compressed or widened, subequal in length to 1 or 2; 4-6 subequal in length, each shorter than 3; 7-10 transverse, subequal in length, each shorter than 6; 11 2 × length of 10, oval; 1-6 punctate with scattered setae; 7-11 setose. Pronotum: twice as wide as long; lateral margin straight basally, rounding to anterior angle, margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc with surface sparsely, finely, irregularly punctate; irregularly, coarsely punctate laterally; basal impression absent; pronotal length 0.7-0.9 mm; pronotal width 1.4-1.7 mm. Scutellum: elongate pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; weakly expanded at humerus; slightly constricted behind humerus; moderately punctate-striate, rows 6-9 obscure on humerus; elytral length 3.4-4.3 mm; elytral width 2.0 mm. Venter: episternum punctate; epipleuron finely punctate, setose; 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 semicircular, deeply emarginate medially in male, truncate in female. Leg: punctate; tibia with fringe of setae on inner margin of apex. Total length: 4.3-5.6 mm.

Diagnosis.

This species is one of the reddish-brown to yellow, nearly rectangular species, which includes Cephaloleia cognata and Cephaloleia dilaticollis . It can be easily distinguished from the other two species by the elytral puncture rows 6 to 9 being obsolete on the humerus.
