First report of three complete mitochondrial genomes of the long-finned charr Salvethymus svetovidovi Chereshnev et Skopetz, 1990 (Salmoniformes: Salmonidae) with phylogenetic consideration

The complete mitochondrial genome was sequenced in three individuals of long-finned charr Salvethymus svetovidovi from Lake El'gygytgyn (Chukotka Peninsula, Russia). The genome sequences are 16,655 bp in size and the gene arrangement, composition, and size are similar to the charr genomes published previously. The difference between the three genomes studied is low, 0.07%. Our results support the phylogenetic closeness of Sl. svetovidovi with representatives of the genus Salvelinus and their origin from a common ancestor. A placement of Sl. svetovidovi in the phylogenetic tree is strictly defined and this taxon should be included in the genus Salvelinus.
