Ecological Risk Screening Summary - Trichomycterus duellmani (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 duellmani is a freshwater parasitic catfish from South America. It has not been reported outside of its native range of the Tupiza River basin in Bolivia. Due to lack of introduction history, the history of invasiveness is uncertain. This species has a low climate match with the contiguous United States. New Mexico was the only State with a medium climate score. Due to the lack of information about potential introductions, the certainty of assessment is low. The overall risk posed by this species is uncertain.
