What Family of the Animal Kingdom does the Dorcopsis belong?

The black dorcopsis is a species of marsupial in the family Macropodidae.It has black upper parts and dark brown underparts. It has a long muzzle, a naked snout, small rounded ears and a tail which lacks hair on its hind half. Its forelimbs are robust but its hind limbs and feet are relatively small. Adults reach a length of between 29 and 39 inches (74 and 99 cm) with a tail of 11 to 16 inches (28 to 41 cm) and weigh around 2 kilograms.

The black dorcopsis is believed to be mainly nocturnal but may move around during the day in dense forest. It feeds on shoots, leaves, grasses, fruit and roots which it gathers with its mouth and manipulates with its fore paws. A young black dorcopsis develops in its mother's pouch. There are four nipples in the pouch despite the fact that there is normally only a single juvenile developing there at any one time.

The black dorcopsis is known from a single location, Goodenough Island at the eastern end of Papua New Guinea where it has a total extent of occurrence of less than 100 square kilometres.
