Isoodon fusciventer

The quenda (Isoodon fusciventer), also known as the southwestern brown bandicoot or western brown bandicoot, is a small marsupial species endemic to Southwest Australia.

Though it was originally treated as a subspecies of the southern brown bandicoot (Isoodon obesulus), such as by the IUCN where it is given the status of least concern, a 2018 paper proposed to raise it to species rank due to molecular and morphological analysis which revealed it was more closely related to the golden bandicoot (Isoodon auratus).
