SSAR 9th Edition Comments:
Native to Cuba, The Bahamas, Cayman Islands, and Honduras. It was introduced in Georgia (Brennan et al., 2022, Herpetological Review 53: 272–273) and established during the 1930s at the Opa-Locka Zoo, Miami-Dade County, Florida (Barbour, 1936, Copeia 1936: 113). It was subsequently introduced as a biological control (Weigl et al., 1969, Copeia 1969: 841–842) and via the pet trade (Duellman and Schwartz, 1958, Bulletin of the Florida Museum of Natural History. Biological Sciences. 3: 181–324; King, 1960, Quarterly Journal of the Florida Academy of Science 23: 71–73) and has since been found from Key West, Monroe County north to Jacksonville, Duval County (Alfonso and Krysko, 2019, Leiocephalus carinatus armouri. Pages 391–393 in Krysko et al. (Editors) Amphibians and Reptiles of Florida. University Press of Florida, Gainesville, Florida). The English name Saw-scaled Curlytail is used by Hedges et al. (2019, Caribbean Herpetology (67): 1–53).
