Taxonomic Comments
Harris and Mayden (2001) used molecular data to examine phylogenetic relationships of major clades of Catostomidae. In all trees, SCARTOMYZON was paraphyletic and embedded in MOXOSTOMA, and CATOSTOMUS was never recovered as monophyletic (XYRAUCHEN was embedded within CATOSTOMUS). They concluded that the phylogenetic relationships and taxonomic composition of taxa presently included in MOXOSTOMA and SCARTOMYZON are in need of further study, as are the relationships and composition of the genera CATOSTOMUS, CHASMISTES, DELTISTES, and XYRAUCHEN, and the phylogenetic affinites of ERIMYZON and MINYTREMA.

See also Smith (1992) for a study of the phylogeny and biogeography of the Catostomidae.

Range Extent Comments
Lower Great Lakes and Mississippi River basins from Minnesota and Pennsylvania to the Gulf; Atlantic and Gulf Slope drainages from Cape Fear River, North Carolina, to Colorado River, Texas (but absent from most of Florida peninsula); frequently observed but rarely in large numbers (Page and Burr 1991). See Campbell (1994 COSEWIC report) for information on occurrences in Canada (rare in Ontario).
Occurrences Comments
This species is represented by a large number of subpopulations and locations.
Threat Impact Comments
Localized threats may exist, but on a range-wide scale no major threats are known.
Ecology & Habitat

Habitat

Typically in long deep pools of clear, firm-bottomed (clay, sand, or gravel), small to medium rivers; sometimes in small turbid creeks and overflow lakes and impoundments. Intolerant of extensive siltation. Spawns in riffle areas.

Reproduction

Spawns in late winter and spring in south, in spring and summer in north. Eggs hatch in 7-12 days (Becker 1983).
