Description
Elongate; subparallel; subdepressed; head (except yellow frons) antennae, and scutellum black; pronotum reddish or yellowish with black macula on anterior margin behind head which varies from semicircular to triangular in shape; elytra black with yellow longitudinal vitta, width of vitta varies from interspace 1 to interspace 7, not narrowing; venter with pro-, meso-, and metasterna yellow medially, black laterally, abdominal sterna 1 yellow medially, black laterally, 2–5 black medially, yellow laterally; legs with femur yellowish, tibia and tarsi black. Head: vertex punctate, medial carina present; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, clavate, elongate; 2–3 transverse, projection on inner apical angle; 2 ¼ length of 1, shortest; 3–4 subequal; 5–10 transverse, subequal in length; 11 rounded at apex, 2× length of 10; 1–3 punctate with scattered setae; 4–11 setose. Pronotum: quadrate; lateral margin straight then rounding to anterior angle, margined; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc flattened; surface impunctate; basal impression absent; pronotal length 1.0–1.3 mm; pronotal width 1.3–1.7 mm. Scutellum: triangular; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, rows obsolete at apex; elytral length 4.1–5.1 mm; elytral width 1.7–2.1 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. Leg: robust, short; femur punctate; tibia with spoon-like depression at apex, tuft setae on inner margin. Total length: 5.7–7.1 mm.
Diagnosis
This species is similar to Cephaloleia belti, Cephaloleia consanguinea, Cephaloleia erugatus, Cephaloleia semivittata, Cephaloleia variabilis, and Cephaloleia vicina. It can be distinguished by the elytral puncture rows being obsolete apically, by the impunctate pronotum, and by the pro-, meso-, and metasterna being punctate laterally.
Distribution
Costa Rica.
