Means of Introduction: Unknown; probable bait bucket releases.
Status: Established in Georgia, North Carolina, and South Carolina.
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.
