Abstract

The Tocantins river basin was one of the few regions in Brazil considered free of Golden Mussel, Limnoperna fortunei (Dunker, 1857). This is an invasive species that has been dispersing throughout South America since 1990. We report the first record of this species in the state of Tocantins. Its presence there represents a problem in the region and a major alert for the Amazon Basin. The Tocantins river basin constitutes one of the gateways to the Amazon Basin.
