Cephaloleia sandersoni Staines, 1996 – Wikispecies link – Pensoft Profile
- Cephaloleia coeruleata Sanderson 1967[1]: 137. (homoym of Cephaloleia coeruleata Weise 1911a[2] (misspelling of Cephaloleia caeruleata Baly).
- Cephaloleia sandersoni Staines 1996[3]: 57 (replacement name for Cephaloleia coeruleata Sanderson). Staines 2008[4]: 1 (key), 2009a[5]: 21 (noted).
Description
Oval; convex; metallic blue, venter and legs dark brown with bluish sheen. Head: vertex finely punctate, medial sulcus absent; frons projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 clavate, subequal in length to 3; 2 transverse, ½ length of 1; 3 elongate; 4–10 elongate, subequal in length, each shorter than 3; 11 2× length of 10, subequal in length to 1 and 3, acutely pointed at apex; 1–2 punctate with scattered setae; 3–11 setose. Pronotum: transverse; lateral margin evenly arcuate from base to anterior angle, margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface uneven, with two vague, rounded depressions between middle and lateral margin; surface sparsely, irregularly punctate, alutaceous; basal impression absent; pronotal length 1.1 mm; pronotal width 1.9 mm. Scutellum: broadly triangular; impunctate. Elytron: lateral margin slightly expanded apically, 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 3.4 mm; elytral width 2.4 mm. Venter: prosternum impunctate medially, rugose laterally; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna punctate; suture between sterna 1 and 2 complete; last sternite with apical margin broadly sinuate in male, less so in female; pygidium setose. Leg: slender; punctate; tibia with fringe of golden setae at apex. Total length: 4.7–5.4 mm.
Diagnosis
This species is similar to Cephaloleia barroi. It can be distinguished by the sparsely punctate vertex of the head, by the straight lateral margins of the pronotum, and by antennomeres 1 and 2 being transverse and subequal in length.
Host plant
Adults have been collected in Thrinax sp. inflorescences (Arecaceae) (Sanderson 1967[1]).
Distribution
Jamaica.

Holotype: Jamaica, Grier Mount on Mount Diablo (St. Catherine Parish), 3000 ft., February 30, 1953, R. A. Howard and G. R. Procter, ex. inflorescence sheaths of Thrinax (INHS).
Specimens examined
