Description
Elongate; subparallel; subdepressed; head (except yellow frons) and scutellum black; antennae black or antennomeres 9–11 yellow; pronotum yellowish with black maculae on anterior and basal margins connected by narrow black vitta; elytra brown or black with yellow longitudinal vitta from base to apical ¼ from puncture rows 4 to 8, lateral margin black or yellow; venter with prosternum yellow, meso- and metasterna yellow medially, black laterally, abdominal sterna 1–4 black with yellow laterally, 5 totally black; leg with tibia and tarsi dark; femur yellow, dark at apex; coxae dark. Head: vertex punctate near eyes, center impunctate, medial sulcus absent; frons not projecting; not depressed between eyes. Antenna: reaches beyond humerus; slender; antennomere 1 elongate, as long as 2–4 combined, clavate, compressed laterally; 2 transverse, ½ length of 1; 3 transverse, longer than 2, projection on inner apical angle; 4–10 transverse; 4 shorter than 3; 5 subequal in length to 3; 6–10 subequal in length, each shorter than 5; 11 as long as 3 or 5, rounded at apex; 1–2 punctate with scattered setae; 3–11 setose. Pronotum: quadrate; lateral margin straight, slightly divergent then rounding to anterior angle, margined; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc subconvex; surface sparsely punctate; basal impression absent; pronotal length 1.1–1.3 mm; pronotal width 1.4–1.6 mm. Scutellum: triangular; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, rows converge and unite apically; elytral length 4.9–5.6 mm; elytral width 2.0–2.3 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin sinuate in male, truncate in female. Leg: slender; impunctate; tibia with fringe of setae on inner margin of apex. Total length: 6.3–7.1 mm.
Diagnosis
This species is similar to Cephaloleia belti, Cephaloleia consanguinea, Cephaloleia erugatus, Cephaloleia semivittata, Cephaloleia triangularis, Cephaloleia trivittata, and Cephaloleia vicina. It can be distinguished by elytral puncture rows being distinct apically, by antennomere 1 being as long as 2 to 4 combined, by the elytral puncture rows converging and uniting apically, and by the sutural angle of the elytra without a small tooth.
Distribution
Colombia, Panama.
