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. Likely aquarium introductions.

Status: Failed in western portion of panhandle of Florida and in 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.

Remarks: A single specimen was taken from a small stream in the Ochlockonee River drainage west of Tallahassee in Leon County, Florida (Swift et al. 1977; Lee et al. 1980 et seq.). The specimen (UF 56238, formerly FSU 6238) was collected in 1959.  Swift et al. (1977) believed the Florida panhandle record was the result of an introduction since all other localities known to them were close to the coast. However, in peninsular Florida Jordanella floridae occurs naturally far inland (e.g., the Kissimmee River drainage).  We regard this location as native for this reason.
