Cephaloleia unctula Pic, 1923 – Wikispecies link – Pensoft Profile
- Cephalolia unctula Pic 1923[1]: 8. Uhmann 1938a[2]: 409 (noted).
- Cephaloleia unctula Pic. Uhmann 1957b[3]: 27 (catalog), 1961b: 24 (noted); Descarpentries and Villiers 1959[4]a: 139 (types); McKenna and Farrell 2005[5]: 121 (phylogeny).
Description
Small; elongate; subparallel; subconvex; reddish-brown; eyes darker. Head: vertex punctate, with medial carina; frons impunctate, not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 elongate, longer than 2 and 3 combined, slightly incrassate, apical margin produced with horn-like projection; 2–6 elongate, cylindrical; 2 longer than 3; 3 longer than 4; 4–6 elongate, subequal in length; 7–10 transverse, subequal in length, each shorter than 6; 11 pointed at apex; 1–6 punctate with scattered setae; 7–11 setose. Pronotum: transverse; lateral margin sinuate for basal ¾ then rounding to anterior angle, canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc flattened; surface densely, coarsely punctate; basal impression absent; pronotal length 1.0–1.2 mm; pronotal width 1.2–1.4 mm. Scutellum: triangular, impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, punctures large, slightly confused apically; elytral length 3.4–3.7 mm; elytral width 1.5–1.7 mm. Venter: pro-, meso-, and metasterna impunctate; abdominal sterna impunctate, glabrous; suture between sterna 1 and 2 complete. Leg: slender; impunctate; tibia with fringe of setae on inner margin of apex. Total length: 4.5–5.0 mm.
Diagnosis
This species is similar to Cephaloleia interstitialis, Cephaloleia striata, Cephaloleia subdepressa, and Cephaloleia truncatipennis. It can be distinguished by the lack of a transverse basal impression on the prontum and by antennomere 1 being longer than 2 and 3 combined.
