Introduction of Leptodactylus labyrinthicus (Spix, 1824) (Anura: Leptodactylidae) in central Amazonia, Brazil

Abstract

This note reports new records of Leptodactylus labyrinthicus in central Amazonia (Manaus, Brazil). We found a small population on the banks of a small polluted tributary of the Negro river. The knowledge about the natural species range suggests that the population was introduced, probably carried to Manaus for commercial production.
