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 punctatissimus is a tropical species of parasitic, freshwater catfish native to the Araguaia River basin in Brazil. This species is a parasite of other fish in its native range, but information is lacking about the potential risks it may pose to the contiguous United States. The climate match to the contiguous United States is low overall, with a medium match in southwestern Florida. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. No introductions of this species have been reported, so the history of invasiveness is uncertain and the certainty of
assessment is low. Overall risk posed by this species is uncertain.
