Taxonomy
In 2002 it was discovered that the originally named mountain brush-tailed possum of Australia actually consists of two separate species. Due to taxonomic rules, the northern population has been renamed with the common name short-eared possum but will keep the scientific name Trichosurus caninus, while the southern population has been named with the common and scientific names mountain brush-tailed possum (Trichosurus cunninghami). This is because the original type specimen of the species was from the northern population, and therefore must keep the original scientific name.
