Cephaloleia bicoloriceps Pic, 1926c – Wikispecies link – Pensoft Profile
- Cephalolia bicoloriceps Pic 1926c[1]: 13.
- Cephaloleia bicoloriceps Pic. Uhmann 1957b[2]: 16 (catalog); Descarpentries and Villiers 1959[3]a: 139 (types).
Description
Oblong-elongate; subdepressed; shining; head, antennae, pronotum (except lateral margins), scutellum, apical ½ of elytra, venter, and femora black; tibiae and tarsi paler; basal ½ elytra yellowish, some specimens have a black sutural vitta which narrows apically to the darker apical ½; elytra with lateral and apical (almost to sutural angle) margins pale. Head: vertex moderately punctate, medial sulcus absent; eye convex; frons not projecting; depressed between eyes. Antenna: reaches beyond humerus; slender; antennomere 1 elongate, not incrassate; 2 ½ length 1; 3–4 elongate, each subequal in length to 1; 5–10 transverse, decreasing in length, each shorter than 4; 11 longer than 10, pointed at apex; 1–6 punctate with scattered setae; 7–11 setose. Pronotum: quadrate; lateral margin straight for basal ½ then slightly rounding to anterior angle, canaliculate; anterior angle angulate, slightly produced; posterior angle acute; anterior margin straight; disc subconvex, with medial longitudinal impression, narrowing basally; surface sparsely, strongly punctate; pronotal length 1.2–1.4 mm; pronotal width 1.4–1.6 mm. Scutellum: pentagonal; punctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle with small tooth; humerus rounded, slightly produced; constricted behind humerus; finely punctate-striate; elytral length 3.9–4.2 mm; elytral width 2.0–2.2 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 emarginate medially in male, rounded, entire in female. Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.4–5.7 mm.
Diagnosis
This is a bicolored species with the apical section of the elytra darker. It is most similar to Cephaloleia apicenotata and Cephaloleia bicolor. It can be distinguished by the straight lateral margins of the pronotum, by antennomere 2 being elongate, and by the elytral punctures being distinct apically.
Distribution
Bolivia, Brazil, Colombia, Ecuador.
