Open encyclopedia reference

The western swamp turtle or western swamp tortoise (Pseudemydura umbrina) is a critically endangered species of freshwater turtle endemic to a small portion of Western Australia. It is the only member of the genus Pseudemydura in the monotypic subfamily Pseudemydurinae.

It is the sister taxon to the subfamily Chelodininae. As a consequence of the greatly altered habitat in the area in which it occurs near Perth, Western Australia, it exists in small fragmented populations, making the species critically endangered.
