Eisenia nordenskioldi is an earthworm widespread in Northern Asia and adjacent regions. It is known for its high
morphological, karyotypic, and genetic variation, and contains two subspecies, the pigmented E. n. nordenskioldi
and the unpigmented E. n. pallida. We obtained almost complete sequences of mitochondrial genomes (without
the control region and parts of the flanking tRNAs) for six genetic lineages of E. n. nordenskioldi, two for E. n.
pallida, as well as for three congeneric outgroups. These genomes had gene content and arrangement typical for
Annelida. Nucleotide and amino acid diversity among E. nordenskioldi lineages was almost as high as between
them and the outgroup species. E. nordenskioldi was split into two clades, one containing E. n. nordenskioldi
lineages 6 and 9, and the other comprised the rest of the lineages. We could not resolve relationships of these two
clades with E. tracta; most datasets used recovered this species as the sister group to E. n. nordenskioldi lineages 6
and 9, but not with high statistical support. According to mtDNA data, neither E. n. nordenskioldi nor E. n. pallida
are monophyletic, and the same could be true for E. nordenskioldi as a whole, which suggest a revision of the
systematics of E. nordenskioldi complex.
