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.
Asolene spixii is an aquatic freshwater snail native to South America. This species has a medium climate match with the contiguous U.S., with the areas of highest match located in the southeastern U.S. This species is prohibited from import and interstate transport in the United States, although it has been reported as in trade in Hawaii. There have been no documented introductions of A. spixii outside of its native range, so potential impacts of introduction to the U.S. remain unknown. Overall risk assessment category is uncertain.
