The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Means of Introduction: Unknown; possible bait bucket introduction. Bart et al. (1994) suggested that Tussahaw Creek may be the point of entry of this species into the Ocmulgee River system and that Lake Jackson is currently preventing its dispersal to other parts of the water system.

Status: Reported from Georgia.

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.

Remarks: Tussahaw Creek is the only known record of this species in the Ocmulgee River system. That record is based on six specimens taken by Georgia Department of Natural Resources' personnel (Bart et al. 1994). There is a questionable previous report of this species from the Altamaha drainage (which includes the Ocmulgee) by Ramsey (1965), but his report was not based on museum specimens (Bart et al. 1994). Dahlberg and Scott (1971a) also included this species, perhaps on the basis of Ramsey's report, but with no details. This species was not reported in surveys conducted in this area during the late 1970s (Bart et al. 1994). The native population east of the Mobile Bay basin are genetically distinct from those found elsewhere and probably represent an undescribed species. In terms of external morphology, however, the eastern Gulf slope population seems to be totally indistinguishable from specimens taken from other areas (Gilbert 1998).
