The Ifola tree kangaroo ( Dendrolagus notatus ) is a species of kangaroo that occurs in the Bismarck Mountains in central Papua New Guinea at altitudes between 900 and 3100 m above sea level.
features
The Ifola tree kangaroo is a relatively large, stocky short-tailed tree kangaroo with relatively short hind feet. Females of the Ifola tree kangaroo reach a head body length of 51.5 to 63 cm, males are larger with 58 to 69 cm. The tail is roughly the same length in the females (43 to 54 cm) and in the males (43.5 to 56.5 cm). The weight of the females is 6 to 6.5 kg, that of the males 7 to 9.1 kg. The thick fur is light to dark brown. The limbs and sometimes the face, the neck or the whole head are lighter than the trunk. The tail is more greyish to yellowish, sometimes a bit banded. The base of the tail is set off from the trunk by a yellowish ring that extends ventrally to the cloaca. The ears are short and hairy.
Habitat and endangerment
The Ifola tree kangaroo lives solitary in tropical mountain rainforests and in mossy cloud forests at heights of 900 to 3100 meters above sea level. Primarily due to human hunting and deforestation in order to gain arable land, the Ifola tree kangaroo is classified as endangered by the IUCN . It has already disappeared from the Schrader Mountains .
Systematics
The Ifola tree kangaroo was described in 1916 by the German zoologist Paul Matschie , who was head of the mammal department at the Zoological Museum in Berlin at the time. It was later assigned as a subspecies to the Doria tree kangaroo ( Dendrolagus dorianus ) and classified as an independent species again in a study on the phylogeny of tree kangaroos in mid-2018 .
