Complete mitochondrial genome of the least weasel (Mustelidae) in Korea.

The complete mitogenome (MF459691) of contains total 16,502 bp in length and consists of a control region and a conserved set of 37 genes. The phylogenetic tree of the family Mustelidae constructed using 18 mitogenome sequences from 16 mustelid species of 6 genera shows that the mustelid species are separated into two main groups. All the members of the genus form a monophyletic group, which has the genus as sister clade, and the clade of the two genera is sister to that of the genera and . Among species of the genus , with the exclusion of with as sister species, all the other species of the genus are well grouped. All members of are well placed within the species clade with the clade of and as sister group.
