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 tupinamba is a small catfish native to two tributaries of the Ribeira de Iguape River in southeastern Brazil. 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. This species has not been reported outside of its very limited native range. Therefore, history of invasiveness is classified as No Known Nonnative Population. Certainty of this assessment is low due to lack of information on the species. T. tupinamba has a medium overall climate match with the contiguous United States, with high match in eastern Florida, Georgia, and Texas but low match across much of the northern and western United States. Overall risk posed by this species is Uncertain.
