† Populations may not be currently present.
Means of Introduction: Unknown, possible bait bucket release.
Status: Established, probably as a result of an introduction, in the Yadkin drainage, North Carolina (Menhinick 1991).
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
