Common name: Rosefin Shiner
available through www.itis.gov
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).

† Populations may not be currently present.
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.
