Comments: Kristmundsdottir and Gold (1996) used mtDNA restriction site analysis to study systematics and biogeography and identified four major mtDNA-based phylogeographic clades: Chocktawatchee, Apalachicola, Mobile, and Western (four lineages, Texas to Mississippi). They found that mtDNA phylogeographic subdivision within C. venusta is not strictly concordant with geographic subdivisions (ranges) of the three nominal subspecies (venusta, cercostigma, and stigmatura); taxonomic revision may be warranted, but further study is needed. This species was removed from genus Notropis and placed in genus (formerly subgenus) Cyprinella by Mayden (1989); this change was adopted in the 1991 AFS checklist (Robins et al. 1991). See Mayden (1989) for synonymy.
