is the list earlier from Zootierliste, or the Chester records? I'm interested in why fruticus is still being used if the former. The type specimen of rufogriseus was from King Island, and all the island populations around Tasmania are now quite rightly treated as being the same (i.e. M. r. rufogriseus). There are thus only two subspecies, the nominate rufogriseus on Tasmania and surrounding islands, and banksianus on the mainland.
It's my understanding, and please correct me if I'm wrong, that all M. rufogriseus in US and European zoos are of the subspecies M. r. rufogriseus and that there are not any banksianus outside Australia. Is that correct?
