Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Hypostomus albopunctatus is a catfish native to the Paraná-Paraguay river basin in Brazil, Paraguay, and Argentina. This species has no documented history of introduction in the United Statees or elsewhere outside its native range, and it is not known to be in trade. However, unidentified species of Hypostomus are established in the United States. Climate match to the contiguous United States was medium overall, with high match in peninsular Florida. Because of the lack of documented introduction history and substantial taxonomic uncertainty, certainty of this assessment is low and overall risk is uncertain.
