The mountain cuscus (Phalanger carmelitae) is a species of marsupial in the family Phalangeridae found in West Papua, Indonesia and Papua New Guinea.[2]
Taxonomy
The mountain cuscus belongs to the family Phalangeridae and the genus Phalanger. It was first described by Oldfield Thomas in 1898. The species includes two recognized subspecies: the nominate P. c. carmelitae Thomas, 1898, and P. c. coccygis Thomas, 1922.[3]
Description
The mountain cuscus has a head-body length of 37–43 cm, a tail length of 31–36.5 cm, and weighs 1.7–2.6 kg. Its thick, woolly fur is dark, ranging from chocolate-brown to blackish and occasionally dark grayish-brown, on the back, with a white belly. The tail is black with a white distal tip and is coarsely tuberculated. The skull is medium-sized, with a condylobasal length of 70–88 mm, a relatively short rostrum, a large posterior upper premolar and molars, the second upper premolar always present, and three unicuspids on each side of the lower jaw.[4]
The mountain cuscus is most easily confused with the silky cuscus (P. sericeus), which differs in having a smooth tail without tuberculation, a shorter or absent white tail tip, the second upper premolar absent, and usually only one or two unicuspids on each side of the lower jaw.[4]
Behavior
The mountain cuscus is nocturnal and arboreal, resting during the day in tree hollows and in tangles of epiphytes and Pandanus fronds.[5] At night it spends approximately 40% of its time feeding, around 25% resting, and the remainder traveling. Males have been recorded using 11–13 dens per year, spaced an average of 115 m apart, while females use 12–19 dens per year spaced an average of 124 m apart.[4]
Male mountain cuscuses move at an average speed of 59 m/h across a home range of approximately 4 ha, while females travel at an average of 37 m/h across home ranges of 2–8 ha. Adjacent home ranges overlap only slightly, with male home ranges overlapping by an average of 0–22% and female home ranges by only 0–5%.[4] The population trend is considered stable.[2]
