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.

Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. There are no documented introductions of this species outside of its native range. History of invasiveness is uncertain. Certainty of the assessment is low due to lack of information. T. taczanowskii has a low overall climate match with the United States. Overall risk posed by this species is uncertain.
