In this study we used sequence data from the entire mtDNA cytochrome b gene to reconstruct patterns and times of diversification in the roach genus Rutilus. The genus is present with numerous endemic species in the Eastern peri-Mediterranean area and with a few widespread species in Central Europe. Our phylogenetic results do not support the subdivision into two subgenera proposed on morphological grounds. Within R. pigus and R. rutilus we identify highly divergent and allopatric mitochondrial lineages. The deeper splits in the genus phylogeny date back to the middle Miocene; the main diversification took place at the Miocene-Pliocene boundary.
