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.
Scleronema angustirostre is a poorly-studied trichomycterid catfish from Uruguay. Along with its taxonomic family, S. angustirostre is listed as a prohibited species in the state of Florida. The species has no history of introduction outside its native range and the climate match to the Contiguous U.S. was low. Therefore, the overall risk to the contiguous U.S. is uncertain.
