Nucleotide sequence variation at the cytochrome b locus was investigated in five Solea species, together with a reappraisal of meristic data and a review of allozyme data pertinent to their systematics. S. aegyptiaca, considered a synonym of S. solea, and S. (Pegusa) impar, considered a synonym of S. (P.) lascaris, are shown to be valid species according to the morphological, phylogenetic, genotypic, and biological species definitions. The validity of the genus Pegusa was examined in the light of both allozyme and cytochrome b gene sequence data.
