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 scabriceps is a South American suckermouth catfish native to the São Mateus River basin in Brazil. The history of invasiveness is uncertain. It has not been reported as introduced or established anywhere in the world outside of its native range. However, unidentified species of Hypostomus are established in the United States. The climate match for the contiguous United States was medium with all States but one having a low individual climate score. Florida had an individually high climate match. The certainty of assessment is low. Limited information was found on this species. The overall risk assessment category for H. scabriceps is uncertain.
