Perameles myosuros

Extinct species of bandicoot

Perameles myosuros, the south-western barred bandicoot or marl, is a recently extinct species of bandicoot that was native to the southern parts of Western Australia. Initially described in 1841 it was later made a subspecies of the extant Perameles bougainville before being restored to species level in 2018, based on museum specimens. Of particular note was that the females were significantly larger than the males in P. myosuros, which is an unusual trait amongst mammals, whereas the sexes were the same size in P. bougainville.
