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.

† Populations may not be currently present.

Means of Introduction: Unknown; possible bait bucket release.

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: Lee et al. (1980 et seq.) depicted the Chestatee River record on their dot distribution map, but these authors did not provide any additional details. Based on unpublished files, originally gathered to generate the Atlas account and map, the site is identified as Chestatee River near Tate bridge, Lumpkin County, Georgia. That record is apparently based on a collection deposited at the University of Georgia (Dahlberg and Scott 1971a). In their list of freshwater fishes known from Georgia, Dahlberg and Scott (1971a) recorded Notropis xaenocephalus from both the Alabama and Chattahoochee river drainages. However, Dahlberg and Scott (1971a, 1971b) apparently did not consider it to be introduced to the Chattahoochee. In their summary table on fishes found in the southeastern United States, Swift et al. (1986) listed this species as native to the Coosa and Cahaba river drainages, but they did not make note of its occurrence in the Chattahoochee drainage.
