The complete mitochondrial genome sequences of the two sister species, Scandinavian willow ptarmigan Lagopus lagopus and Icelandic rock ptarmigan Lagopus muta, were characterized using next-generation sequencing. The mitogenome for willow ptarmigan was 16,677 bp long, with base composition of 30.3% A, 30.8% C, 13.3% G and 25.6% T, with a GC content of 44.1%, while for rock ptarmigan mitogenome was 16,687 bp long, with base composition of 30.2% A, 30.6% C, 13.4% G and 25.8% T, and a GC content of 44.0%. Like other Galliformes species, the mitogenomes comprised of 13 protein-coding genes, 22 tRNA, 2 rRNA and 2 non-coding regions; and control region (D-loop). All genes except ND6 and 8 tRNA were encoded on theþstrand. All protein-coding genes started with ATG, except for COX1, where a GTG codon was present in both willow ptarmigan and rock ptarmigan. Phylogenetic analysis of the two novel mitogenomes with other Galliformes species demonstrates close relationship within the Tetraoninae subfamily.
