As of 2010, Florida had the largest number of introduced and established non-indigenous herpetofaunal species in the world. With the advent of molecular methodologies, researchers now are able to test hypotheses regarding introduction pathways, species identity, and native range origins. African Agamas, Agama Daudin 1802, found in Florida are hypothesized to be the African Rainbow Lizard, A. agama africana Hallowell 1844, based on color patterns and hypothesized native range origins (i.e., Benin, Ghana, and Togo) of imported specimens for the pet trade. However, recent systematic studies within the native range of the Agama complex have resulted in multiple taxonomic revisions, which calls into question the species identity of introduced populations in Florida. The purpose of this study is to determine the species identity of African agamas within Florida, as well as the native range origins of Florida populations. We conducted a comparative maximum likelihood analysis between individuals from Florida and individuals from the native range. Based on our results we determined that the species found in Florida is Agama picticauda from western Africa.
