Resumen:
There are many cases of animals reported in localities away from natural areas of distribution for the species. With respectto native freshwater turtles of Argentina and bordering countries, several populations (and single specimens) were reportedfor areas that cast doubts about their origin, due to not only the long distance from other known localities but also thegeographical barriers that are in between. The present work provides a review of localities of the native turtle speciesHydromedusa tectifera, Phrynops hilarii, Acanthochelys pallidipectoris, A. spixii and Trachemys dorbigni in Argentina, Bolivia,Brasil, Paraguay and Uruguay, and adds new records for some of these species for Argentina. We also employ an analysis torecognise core and extralimital populations, and a methodology based on five criteria that must be taken into account toelucidate if one extralimital turtle record is the result of anthropogenic action or a case of natural occurrence. Finally, wediscuss about the origin of extralimital reports of turtles of the mentioned species.
