Only a very small number of fossil specimens are known, the oldest dating back to the Pleistocene, and no other species from the same family have been identified. fasciatus rufus had a more reddish coat than the surviving population. The separation to subspecies was not recognised in the national census of Australian mammals, following W.

The population described by Finlayson occurred in the arid central regions of South Australia, and he thought they had once extended to the coast. fasciatus fasciatus) remains alive today. Two subspecies have been described, but one of these-the rusty coloured Myrmecobius fasciatus rufus Finlayson, 1933, -has been extinct since at least the 1960s, and only the nominate subspecies ( M. Genetic studies have shown the ancestors of the numbat diverged from other marsupials between 32 and 42 million years ago, during the late Eocene. The species is not closely related to other extant marsupials the current arrangement in the order Dasyuromorphia places its monotypic family with the diverse and carnivorous species of Dasyuridae. The numbat genus Myrmecobius is the sole member of the family Myrmecobiidae, one of four families that make up the order Dasyuromorphia, the Australian marsupial carnivores.

The numbat is the faunal emblem of Western Australia. Numbats were recently re-introduced to fenced reserves in South Australia and New South Wales. It is therefore considered an endangered species and protected by conservation programs. The species was once widespread across southern Australia, but is now restricted to several small colonies in Western Australia. It is diurnal and its diet consists almost exclusively of termites. The numbat ( Myrmecobius fasciatus), also known as the noombat or walpurti, is an insectivorous marsupial.
