Disclaimer:

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.

Common name: Redline Darter

Synonyms and Other Names: Nothonotus rufilineatus (Near and Keck 2005; Near et al. 2012).

Taxonomy: available through www.itis.gov

Identification: Similar in size, shape and color to other species of Nothonotus darters, but can be distinguished by the presence of black dashes on the cheek and cream-colored spots on the caudal fin base (Jenkins and Burkhead 1994; Page and Burr 2011).

Size: to 8.5 cm SL

Native Range: Tennessee and Cumberland River drainages; Alabama, Georgia, Kentucky, Mississippi, North Carolina, Tennessee, and Virginia (Jenkins and Burkhead 1994; Page and Burr 2011).

Interactive maps: Point Distribution Maps

Means of Introduction: Unknown.

Status: Established

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.
