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
Costa Rica.
