The toolache wallaby or Grey's wallaby (Notamacropus greyi) is an extinct species of wallaby from southeastern South Australia and southwestern Victoria.

Taxonomy

A species described by George Waterhouse in 1846. The type specimen was collected at Coorong in South Australia. [4] The author cites an earlier name, Halmaturus greyii, published by John Edward Gray in 1843 without a valid description, assigning it to a subgenus of the same name—Macropus (Halmaturus)—and providing the common name of the newly described species as Grey's wallaby. [5] [6] The common name and epithet greyi commemorates the collector and explorer George Grey, who provided the two specimens to researchers at the British Museum of Natural History. [3] A systematic revision has seen the species placed in a subgeneric arrangement as Macropus (Notamacropus) greyi, recognising an affinity with eight other species of the subgenus named as Notamacropus Dawson and Flannery, 1985. [7] An arrangement that elevates the subgenera of Macropus is recognised as Notamacropus greyi. [8] A genetic analysis found that its closest relative is the western brush wallaby. [9]

The common names have also included monkeyface and onetwo. [6] The name Toolache may come from the Ngarrindjeri word rtulatji. [10]

Description

The toolache wallaby was a slim, graceful, and elegant creature that had a pale ashy-brown pelt with a buff-yellow underbelly. [6] [11] The tail was pale grey and became almost white near the tip. The distinct black mark on its face reached from its nose to the eye. The forearms, feet, and tips of the ears were also black. The different colours of the animal also consisted of different textured furs which are believed to have changed seasonally or varied depending on the individual. The body measurements differed between males and females. In general, male toolache wallabies had a head and body length up to 810 mm while females measured up as 840 mm. Despite the females being taller, males had longer tail lengths at about 730 mm while the female's tail length was 710 mm. [12]

Behaviour

The toolache wallaby was a nocturnal animal, foraging for vegetation during the twilight hours of the day. [11] Their movements were unusual and extremely rapid, able to outpace almost any terrestrial predator; they were known to evade the fastest dogs of the colonial hunters. [6]

Habitat

The toolache wallaby occupied the southeastern corner of Australia to the western part of Victoria. The preferred habitat ranged from swampy short grassland areas, to taller grassed areas of the open country. Toolache wallabies were known to be sociable creatures who lived in groups; they were often seen resting and grazing in groups. [12]

Threats

A combination of numerous threats caused the decline and eventual extinction of the toolache wallaby. One of the largest factors was the destruction of its habitat. Since swamps were an important part of its habitat, once they were cleared out, much of the vegetation went with it. Besides the destruction of its habitat, the introduction of predators, such as the European red fox, began to kill off the species as well. Additionally, the animal was also hunted for sport and for its pelt. [12]

Extinction

The toolache wallaby only survived 85 years after European occupation. In the 1920s, a conservation effort was made to try to bring the animal back from the brink of extinction. The plan was to capture and breed the last known surviving members of the species in captivity. This effort ended in disaster after 10 of the 14 of them were accidentally killed in the attempt to capture them. The remaining four survived in captivity.

The last wild sightings were recorded in 1924, and the last known toolache wallaby survived in captivity until 1939. [2] The species is presumed to be extinct, although extensive research is still being conducted in the region after reports of suspected sightings through the 1970s. However, no members of the species have been sighted since.

Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups. These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent, New Guinea and nearby islands.

<span class="mw-page-title-main">Parma wallaby</span> Species of marsupial

The parma wallaby is a small marsupial macropod mammal native to forests and densely-vegetated areas of northeastern New South Wales, Australia, close to the border with Queensland. There is also an introduced population found in and around Rodney District, just north of Auckland, New Zealand. About the size of a stout cat, it lives mainly under thick plant cover, and is only active at night when it emerges to feed on grasses and small plants. It is the smallest of the wallabies and carries its young in a pouch, as with other marsupials. Shy and elusive, it was believed extinct until its rediscovery in the 1960s.

<span class="mw-page-title-main">Wallaroo</span> Category of marsupial

Wallaroo is a common name for several species of moderately large macropods, intermediate in size between the kangaroos and the wallabies. The word "wallaroo" is from the Dharug walaru with spelling influenced by the words "kangaroo" and "wallaby".

<i>Macropus</i> Genus of marsupials

Macropus is a marsupial genus in the family Macropodidae. It has two extant species of large terrestrial kangaroos. The term is derived from the Ancient Greek μάκρος, makros "long" and πους, pous "foot". Thirteen known extinct species are recognised. The type species is the eastern grey kangaroo.

<span class="mw-page-title-main">Northern nail-tail wallaby</span> Species of marsupial

The northern or sandy nail-tail wallaby is a species of macropod found across northern Australia on arid and sparsely wooded plains. The largest species of the genus Onychogalea, it is a solitary and nocturnal herbivorous browser that selects its food from a wide variety of grasses and succulent plant material. Distinguished by a slender and long-limbed form that resembles the typical and well known kangaroos, although their standing height is shorter, around half of one metre, and their weight is less than nine kilograms. As with some medium to large kangaroo species, such as Osphranter rufus, they have an unusual pentapedal motion at slow speeds by stiffening the tail for a fifth limb. When fleeing a disturbance, they hop rapidly with the tail curled back and repeatedly utter the sound "wuluhwuluh". Their exceptionally long tail has a broad fingernail-like protuberance beneath a dark crest of hair at its end, a peculiarity of the genus that is much broader than the other species. The name unguifera, meaning claw, is a reference to this extraordinary attribute, the purpose of which is unknown.
