Salvethymus svetovidovi, also called the long-finned charr, is a species of Salmonidae fish. It is Endemism to Elgygytgyn Lake in Chukotka, Far East of Russia,[ together with two other species, the small-mouth char Salvelinus elgyticus,][ and the Boganid char, Salvelinus boganidae.]
Taxonomy
The long-finned char is a morphologically aberrant type of Salvelinus; 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 phylogeny placed within this genus; it is probably a sister lineage to the Arctic char ( Salvelinus alpinus) complex.[
