There are four species reported from the Caribbean: Cephaloleia barroi Uhmann, 1959 from Cuba; C. brunnea Staines, 1996 from Trinidad; C. rubra Staines, 1996 from Trinidad; C. sandersoni Staines, 1996 (=Demotispa coeruleata Sanderson, 1967) from Jamaica (Staines 1996). Most Cephaloleia species are not associated with a host plant. Many species with plant associations feed on members of the Zingiberales (see Staines 2004 for a review of the literature). However, a few species (for example: C. facetus Staines, C. formosus Staines, C. vagelineata Pic) feed on or are associated with various Arecaceae (Sandino 1972, Staines 1996). The palm feeders seem to fall into two morphological groups: oval, strongly convex (such as C. sandersoni) and small, flattened species with truncate elytral apices (such as C. facetus). Based on genetic data McKenna and Farrell (2005) found that some Arecaceae-feeding Cephaloleia species formed a distinct clade with other Cephaloleiini genera which feed on Arecaceae. This area needs more investigation to clearly determine the generic placement of a number of species. For this study, measurements were taken with an ocular micrometer. Pronotal length and width were measured along the midlines. Elytral width was measured at the humeri. Elytral length was measured from the base to the apex along the midline. Total length was measured from the base of the antennae to the apex of the elytra. In recording label data from type specimens, a double slash (//) separates data on different labels; brackets ([ ]) include explanatory or label color information. Collection acronyms are from Arnett et al. (1993). Genitalia were extracted and examined. No taxonomic differentiating characters were found on genitalia.1 aStaines, C., L.  uhttps://cephaloleia.myspecies.info/node/1400535nas a2200157   4500008004100000245011700041210006900158300001200227490000700239100001700246700001600263700001700279700002000296700001400316856004700330       2008                        eng d00aPotential and realized feeding niches of neotropical hispine beetles (Chrysomelidae : Cassidinae, Cephaloleiini)0 aPotential and realized feeding niches of neotropical hispine bee  a224-2290 v371 aDescampe, A.1 aMeskens, C.1 aPasteels, J.1 aWindsor, D., M.1 aHance, T.  uhttps://cephaloleia.myspecies.info/node/15
