Ecological Risk Screening Summary - Hypostomus nudiventris (a catfish, no common name) - Uncertain Risk

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 nudiventris is a catfish native to the coastal river drainages in northern Brazil. This species has no documented history of introduction in the United States or elsewhere outside its native range. However, unidentified species of Hypostomus are established in the United States. History of invasiveness is uncertain. H. nudiventris does not appear to be present in trade in the United States or elsewhere. Climate match was low throughout the contiguous United States. However, the match was based on only one georeferenced occurrence; no additional locations were available. Because of the lack of documented introduction history and distribution data coupled with substantial taxonomic uncertainty, certainty of this assessment is low and overall risk is uncertain.
