ZooKeys 436: 1–355. doi: 10.3897/zookeys.436.5766 Abstract The species of the Neotropical genus Cephaloleia Chevrolat, 1836 are revised. We present a key to the known larvae of Cephaloleia (8 species), a key to the 95 species known to occur in Mexico, Central Amer- ica and the West Indies, and a key to the 138 species known to occur in South America. All identification keys were translated to Spanish. Descriptions for the 214 known species of Cephaloleia as well as illustra- tions for 212 species are presented. The following species are removed fromCephaloleia : C. bipartita Pic, 1926c is transferred to Hybosispa Weise, 1910; C. minasensis Pic, 1931 and C. viridis Pic, 1931 are trans- ferred to Stenispa Baly, 1858. The following species are described as new:C. abdita sp. n. from Brazil; C. amba sp. n. from Colombia, Ecuador, and Peru; C. angustacollis sp. n. from Ecuador; C. brevis sp. n. from French Guiana; C. calathae sp. n. from Costa Rica; C. chica sp. n. from Peru; C. conforma sp. n. from Costa Rica; C. crenulata sp. n. from Ecuador; C. gemma sp. n. from Bolivia and Brazil; C. horvitzae sp. n. from French Guiana; C. interrupta sp. n. from Costa Rica; C. kressi sp. n. from Costa Rica; C. lenticula sp. n. from Ecuador, French Guiana, Peru, and Suriname; C. nana sp. n. from Ecuador; C. ochra sp. n. from Ecuador; C. stainesi sp. n. from Costa Rica; and C. susanae sp. n. from Brazil and Ecuador. Cephaloleia simoni Pic, 1934 is treated as Incertae sedis. The larvae ofC. erichsonii Baly, 1858 and C. puncticollis Baly, 1885 are described and illustrated.

The type species is C. nigricornis (Fabricius) designated by Staines (1991(1992)). Cephaloleia is distrib- uted from the south of Mexico to Argentina. The entire genus has never been revised and identifications to species are chal- lenging. There have been four published keys toCephaloleia - Uhmann (1930a) for 22 species from Costa Rica, Uhmann (1936a) for 31 species, Staines (1996) for 88 species from Central America and the West Indies, and Staines (2009b) for five species known from the Caribbean. In this revision we include 214 species. In addition to a general overview of the literature on the taxonomy, ecology, and evolution of Cephaloleia, we present species descriptions for all species and images for all but two species (i.e. C. vittata Staines, 1996 and C. amblys Staines, 1996 whose type specimens were not available for this revision). We have been unable to locate the type of C. simoni Pic, 1934, any specimen identified as C. simoni, or any specimen which can be assigned to this species based on the short original description. We are treating this species as incertae sedis. We also included three identification keys: first a key to the known larvae of Cephaloleia. Then a key to theCephaloleia of Mexico, Central America and the West Indies and finally a key to theCephaloleia of South America. All keys were translated to Spanish. The taxonomy of Cephaloleia species in Central America is very stable as a result of decades of research. Having a key only for the Mexican and Central American species will facilitate species identification for researchers working on this region. The identi- fication of South American species is more challenging because of the high diversity of Cephaloleia in this continent. Although our key to the South American Cephaloleia includes all known species, researchers must remember that there are still many species to be described in this region. This last key is therefore a tool for both the identification and discovery of species in South America. Materials and methods Adult descriptions. For this study, measurements were taken with an ocular microm- eter. Pronotal length and width were taken along the midlines. Elytral width was meas- ured at the humerus. Elytral length was measured from the base to the apex. Total length was measured from the base of the antennae to the apex of the elytra. In record- ing label data from type specimens, a slash (/) divides data on different labels; brackets ([]) contain explanatory information. Data from other specimens are reported nearly as they appear on labels, but with some standardization in the format of dates, puncta- tion, or sequence of information. In specimens examined a question mark (?) indicates unknown province or state. 4 Charles L.
