Аннотация: This is the report about the secondary contact zone of coregonids in the Upper Volga basin. Two mitochondrial DNA (mtDNA) phylogenetic lineages of vendace Coregonus albula (Linnaeus, 1758) living in Lake Pleshcheyevo have been analyzed and compared in terms of morphological characters. These lineages have developed under the conditions of allopatry and are characterized by strong differences of the mitochondrial DNA sequences. The lineages have coexisted in the same lake since the last glaciation maximum (about 10,000years ago). The morphological analysis has shown that representatives of both lineages correspond to C. albula, while slight, morphological variations between lineages indicate different food preferences and locomotor abilities. Scenarios where multiple distinct coexisting phylogenetic lineages are characterized by low levels of morpho-ecological divergence are uncommon. These situations are important for understanding biodiversity dynamics and the mechanisms that drive coexistence, adaptive divergence, hybridization, and extinction when genetically divergent lineages meet in secondary contact.
