New locality for Lepidosiren paradoxa (Fitzinger, 1837) (Dipnoi: Lepidosirenidae) in Argentina

Abstract

This study documents a new locality of the lungfish Lepidosiren paradoxa on the coast of the Entre Rios Province in the lower Paraná River. This finding represents the third southern record of this species on southern of South America. Additionally, as this region has been relatively well sampled both during past decades and currently, I discuss possible reasons why this new specimen has been observed only recently.
