Description
Oblong-oval; subconvex; head, antennae, pronotum, and scutellum dark brown; elytra yellowish with dark brown sutural vitta starting at basal margin, dilated just past scutellum, then gradually narrows to just beyond midline, then only suture darkened, and a brown pointed, ovoid, elongate macula on apical ⅓; venter with prosternum brown, meso- and metasterna brown medially and black laterally, abdominal sterna dark medially and pale laterally; legs yellow. Head: vertex densely punctate, each puncture with short pale seta, medial sulcus absent; frons not projecting; keel between antennal bases; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 longer than 2, thickened; 2–3 transverse, subequal in length; 4–10 transverse, decreasing in length; 11 2× length of 10, rounded at apex; 1–4 punctate with scattered setae; 5–11 setose. Pronotum: transverse; lateral margin straight and convergent from base to apex, canaliculate, especially near apex; anterior angle obtuse, produced; posterior angle acute; anterior margin emarginate behind head; disc convex, surface densely and shallowly punctate; basal impression absent; pronotal length 0.9–1.2 mm; pronotal width 1.3–1.7 mm. Scutellum: pentagonal; micropunctate. Elytron: lateral margin straight, smooth, slightly laminate; apex obtusely rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; punctures large, shallow; humerus nearly impunctate; elytral length 4.0–4.2 mm; elytral width 2.1–2.3 mm. Venter: prosternum impunctate; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna sparsely punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially. Leg: slender; glabrous, impunctate; tibia with fringe of setae on inner margin of apex. Total length: 5.1–5.4 mm.
Diagnosis
This species is similar to Cephaloleia balyi, Cephaloleia deficiens, Cephaloleia dorsalis, Cephaloleia linkei, and Cephaloleia suturalis. It can be distinguished by the black pronotum and by antennomere 1 being longer than 3.
Distribution
Guatemala, Mexico Honduras, Panama.
