Dendrolagus pulcherrimus

The Golden-mantled Tree-kangaroo, Dendrolagus pulcherrimus is a species of tree-kangaroo native and endemic to montane forests of New Guinea. It has chestnut brown short coat with a pale belly, and yellowish neck, cheeks and feet. A double golden stripe runs down its back. The tail is long and has pale rings.
Its appearance is similar to the closely related Goodfellow's Tree-kangaroo. It differs from the latter by having a pinkish or lighter color face, golden shoulders, white ears and smaller size. Some authorities consider the Golden-mantled Tree-kangaroo as a subspecies of Goodfellow's Tree-kangaroo.
The Golden-mantled Tree-kangaroo was discovered in 1990 by Pavel German in Mount Sapau, Torricelli Mountains region of Papua New Guinea. Previously known only from a small area in Torricelli Mountains, another population was discovered at remote areas of Foja Mountains of Indonesia along with several new and "long lost" species in December 2005. The Golden-mantled Tree-kangaroo is the latest large mammal species for Indonesia's biodiversity.
The Golden-mantled Tree-kangaroo is considered as one of the most endangered of all tree-kangaroos. It is extinct in most of its original range.
