Concept ReferenceRobins, C.R., R.M. Bailey, C.E. Bond, J.R. Brooker, E.A. Lachner, R.N. Lea, and W.B. Scott. 1991. Common and scientific names of fishes from the United States and Canada. American Fisheries Society, Special Publication 20. 183 pp.
Taxonomic CommentsHarris 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.
