Description.

Cantharid-like in appearance; oblong; subparallel; subdepressed; dull; head (except at antennal insertions which are brown), antennae (except basal antennomere), and elytra black, pronotum red with inverted black V-shaped vitta from base to apex; venter with pro-, meso-, and metasterna reddish laterally, black medially; abdominal sterna black medially, yellow laterally; legs with base of femur yellowish, rest with upper surface dark, lower surface yellowish. Head: vertex densely punctate, medial sulcus absent; frons not projecting; not depressed between eyes. Antenna: ½ body length; slender; antennomere 1 transverse, ¾ length of 2; 2 elongate; 3 elongate, longer than 1 and 2 combined; 4-10 elongate, subequal in length, each ¾ length of 3; 11 longer than 10, rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse but much narrower than base of elytra; lateral margin straight then rounding to anterior margin, margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin sinuate; disc subconvex; surface punctate, more so laterally; basal impression absent; pronotal length 0.8 mm; pronotal width 1.5 mm. Scutellum: broadly triangular; micropunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; disc flattened behind humerus laterally, irregularly punctate; declivity beginning just behind humerus at puncture row 7 not edged with faint carina; elytral length 4.7 mm; elytral width 2.0 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate each puncture with seta; suture between sterna 1 and 2 complete. Leg: slender; sparsely punctate; tibia with fringe of setae on inner margin of apex. Total length: 6.0 mm

Diagnosis.

This species is similar to Cephaloleia orchideivora . It can be distinguished by the irregular elytral punctation, by not having an additional row of elytral punctures, and by the anterior margins of the pronotum being straight.

Distribution.
