Ecological Risk Screening Summary - Hypostomus rhantos (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 rhantos is a catfish native to the Orinoco River drainage of Venezuela. This species has no documented history of introduction in the United States 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 low overall, with medium match in peninsular Florida and extreme southern Texas. Because of the lack of documented introduction history and substantial taxonomic uncertainty, certainty of this assessment is low and overall risk is uncertain.
