Justification
Listed as Least Concern in view of the large extent of occurrence, large number of subpopulations, large population size, and lack of major threats. Trend over the past 10 years or three generations is uncertain but likely relatively stable, or the species may be declining but not fast enough to qualify for any of the threatened categories under Criterion A (reduction in population size).

Names and Taxonomy

Taxonomy

Comments: Includes P. callarchus, formerly regarded as a distinct species (Lee et al. 1980). NOR chromosomal data support monophyly of the four extant species of Pimephales and suggest that the genus Pimephales belongs in a monophyletic assemblage with, among others, the cyprinid genera Cyprinella and Opsopoeodus (Li and Gold 1991); Coburn and Cavender (1992) also indicated that these three genera are phylogenetically closely related.
