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 straminius is a small catfish endemic to central Colombia. Information on the biology of T. straminius is not widely available. 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 outside of its native range have been documented, so history of invasiveness is uncertain. Certainty of this assessment is low due to lack of information. The climate match with the contiguous United States is low overall, with small areas of medium climate match on the Pacific coast. Overall risk posed by this species is uncertain.
