Abstract
This paper reports information about the presence of three allochthonous reptiles species in Calabria: Testudo marginata, Trachemys scripta elegans and Chamaeleo chamaeleon. The first one was found in three sites located in the Catena Costiera Massif and in the Crati Valley (Northern Calabria). The slider turtle was found in seven different sites throughout all the region. It massively colonised the Angitola artificial lake: here, this turtle lives in natural conditions and its reproduction was confirmed by the presence of nests, eggs and hatchlings. C. chamaeleon is present in sandy coastal habitats near Palmi and Gioia Tauro (Southern Calabria). From a conservationistic point of view, serious damages to autochtonous species could be caused by the spreading of T. scripta elegans: this species has already determined the local extinction of Angitola’s Emys orbicularis populations.
