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 triguttatus is a small catfish native to São Paulo State in southeastern Brazil. This species has not been reported outside of its native range. It is not known to be in trade in the United States, and several States have prohibitions or restrictions on its importation, possession, or trade. History of invasiveness is classified as No Known Nonnative Population. Certainty of this assessment low due to a lack of introduction history and biological information, and only one georeferenced occurrence for climate matching. T. triguttatus has a low overall climate match with the United States, however there is a medium match along the coast of Georgia and in Florida. Overall risk posed by this species is Uncertain.
