mountain brushtail possum
The mountain brushtail possum, or southern bobuck (''Trichosurus cunninghami''), is a nocturnal, semi-arboreal marsupial of the family Phalangeridae native to southeastern Australia. It was not described as a separate species until 2002.〔Kerl A (2001), Possums: the Brushtails, Ringtails and Greater Glider. UNSW Press, Sydney NSW.〕
==Taxonomy==
In 2002, based upon morphometric differences, it was proposed that the mountain brushtail possum, ''Trichosurus caninus'', be reclassified into two distinct species. The northern form was to retain the binomial name ''T. caninus'' but was henceforth to be known as the short-eared possum. The southern population, prevalent in the Victorian Alps was to retain its already designated common name mountain brushtail possum but assigned a new binomial, ''T. cunninghami''. However, genetic divergence between ''T. caninus'' and the putative ''T. cunninghami'' may not support a case for the establishment of a new species.
In 2005 a colony of bobucks was discovered in swamp coastal habitat in south west Gippsland, Victoria. A follow up biodiversity survey uncovered a widespread yet previously unrecorded population of bobucks in coastal habitat and parts of inland Gippsland.
In view of these findings, the currently accepted name, "mountain" brushtail possum, is no longer accurately descriptive. One suggestion is to rename the northern group as the "northern bobuck" and the Victorian animals as "southern bobuck", ''T. cunninghami''.
