Salvethymus svetovidovi, also called the long-finned charr, is a species of salmonid fish. It is endemic to Elgygytgyn Lake in Chukotka, Far East of Russia, ^{[2] [1]} together with two other species, the small-mouth char Salvelinus elgyticus, ^[3] and the Boganid char, Salvelinus boganidae . ^{[4] [3]}

Taxonomy

The long-finned char is a morphologically aberrant type of char; when scientifically first described in 1990, it was placed as the single species in Salvethymus, a new monotypic genus. It is closely related to the true chars in the genus Salvelinus and is phylogenetically placed within this genus; it is probably a sister lineage to the Arctic char (Salvelinus alpinus) complex. ^{[5] [4]}
