Ecological Risk Screening Summary - Trichomycterus papilliferus (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.

Trichomycterus papilliferus is a species of trichomycterid catfish that has been subject to very limited study. Its known distribution is southern Brazil. There is little information on the biology of the fish. T. papilliferus is regulated in multiple States. There have been no reports of the species outside of its native range. The history of invasiveness is classified as No Known Nonnative Population. The overall climate match to the contiguous United States is low. Areas of medium match were found in the Southeast, primarily near coastlines. The certainty of assessment is low due to a lack of information. The overall risk for this species is Uncertain.
