Hypotheses of relationship among genera of Percidae have been conflicting. Based on different phylogenetic premises, the evolution of small benthic forms in Percidae has been interpreted as resulting from either convergence or common ancestry. In order to assess various phylogenetic hypotheses of Percidae we collected complete sequences (1140 bp) of mitochondrially encoded cytochromebfor 21 species of percids. Seven species representing four additional families of Perciformes were used as outgroups. Maximum parsimony and minimum evolution analyses both recovered single shortest trees, and the results of these analyses were generally congruent with one another. All analyses consistently recovered three monophyletic groups in Percidae: Etheostomatinae (Ammocrypta, Crystallaria, Etheostoma,andPercina), Percinae (PercaandGymnocephalus), and Luciopercinae (Stizostedion, Zingel,andRomanichthys). As a result of this analysis we present a revised classification of Percidae and discuss the phylogenetic evidence for the independent evolution of small benthic species within Etheostomatinae and Luciopercinae.
