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.

Identification: Page and Burr (1991); Mettee et al. (1996).

Native Range: From the Perdido River in Alabama and Florida to the Apalachicola basin of Alabama, Florida, and Georgia (Clemmer 1970; Gilbert 1998).

Nonindigenous Occurrences: Swift et al. (1977) reported two collections, of what was tentatively referred to as Hybopsis amblops, from the Ochlockonee drainage in Florida in 1967 (voucher specimens, UF 65225). These fish are now considered to represent a new species, one closely allied to Hybopsis winchelli (=Notropis winchelli). The Ochlockonee specimens of this undescribed species are most likely the result of introduction. Support for this conclusion, as stated by Swift et al. (1977), is based on the "recent vintage of these collections and the fact that extensive previous collecting by many investigators did not disclose the species..."

† Populations may not be currently present.

Means of Introduction: Possible bait bucket release.

Status: Reported in Florida outside of its native range.

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: This species is yet undescribed. It is believed that the fish east of the Mobile drainage are a different species from H. winchelli (Lee et al. 1980).
