Ecological Risk Screening Summary - Trichomycterus trefauti (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 trefauti is a small catfish native to the São Francisco basin, Minas Gerais, Brazil. It is known only from its type locality. There has been no documentation of introductions outside of its native range, so history of invasiveness is uncertain. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. T. trefauti has a low climate match with the contiguous United States, although there is an area of medium match in southwestern Florida. Certainty of this assessment low due to lack of information. Overall risk posed by this species is uncertain.
