Distribution of slider turtle taxa (Trachemys) in Central America and northern South America. Colored distribution ranges follow the last edition of the checklist of the turtles of the world (TTWG 2021). Unnumbered collection sites (circles) are from Fritz et al. (2012) and Vargas-Ramírez et al. (2017); numbered sites are from the present study. Colors of sites reflect their genetic identity. Note the occurrence of Trachemys grayi emolli (sites 9 and 10) within the putative distribution range of T. venusta uhrigi in Costa Rica.
