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.

Lythrurus ardens (Cope, 1868)

Common name: Rosefin Shiner

Taxonomy: available through www.itis.govITIS logo

Identification: Page and Burr (1991); Etnier and Starnes (1993); Jenkins and Burkhead (1994); another commonly used name is Notropis ardens. Snelson (1990) recognized two subspecies, L. a. ardens and L. a. fasciolaris. Dimmick et al. (1996) recognized L. ardens as a species complex; as part of a re-evaluation, they elevated L. a. fasciolaris to species status, and resurrected L. matutinus from synonymy. Mayden et al. (1992) and Gilbert (1998) treated all three species as valid.

Size: 8.5 cm.

Native Range: Atlantic Slope from York River drainage (where probably introduced), Virginia, to the Cape Fear drainage, North Carolina, and in several drainages of the Ohio basin in Virginia and West Virginia (Snelson 1990; Jenkins and Burkhead 1994).

Means of Introduction: Unknown; probable bait bucket release. In Virginia, it was first discovered in the South Anna system (Deep Creek) of the York River drainage in 1968, and probably later spread into the North Anna system where it was first discovered in 1979; the species is presumed to have come from an adjacent portion of the James River drainage (Snelson 1990; Jenkins and Burkhead 1994).

Status: Established in Virginia.

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: In their taxonomic revision, Dimmick et al. (1996) recognized three distinct species in the L. ardens complex and they restricted the range of each of the species. Based on the distribution map given by Dimmick et al. (1996) for the three species, we can assume that records from the Muskingum River drainage, Ohio, represent Lythrurus fasciolaris, those from the York drainage, Virginia, are the true L. ardens, and those found in the Cape Fear drainage likely represent L. matutinus. However, among the L. ardens complex, Dimmick et al. (1996) apparently only recognized populations found in the York River drainage of Virginia as introduced. Snelson (1990) provided details on the distribution of native and introduced populations. Stauffer et al. (1978) and Hocutt et al. (1986) listed this species as probably introduced into the Potomac drainage. However, Stauffer et al. (1978) indicated that it could feasibly be native to that drainage.
