Ecological Risk Screening Summary - Trichomycterus diabolus (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 diabolus is a freshwater catfish native to the Paranapanema River basin in southeastern Brazil. The species has a medium climate match with the U.S., with highest match in Florida. The State of Florida has included the species, and all other species in the genus Trichomycterus, on its list of prohibited species for the State. T. diabolus has not been documented as introduced outside its native range, so potential impacts of introduction are unknown. Overall risk assessment category for this species is uncertain.
