Abstract: An old published record for “Crocodilurus” in Paraguay was almost certainly based on Dracaena paraguayensis Amaral, 1950. Thus, D. paraguayensis Olimpo, and Crocodilurus lacertinus occurs from the Brazilian Pantanal south along the Paraguay River as far as Fuerte (Daudin, 1802) remains restricted to the Amazon and Orinoco river drainages.
