MorphologyRead full entry
Like all members of the genus Presbytis, mitred leaf-monkeys have a short rostrum and weakly-developed brow ridges. Mitred leaf monkeys have long forelimbs and relatively long hindlimbs, which is consistent with their preferred mode of locomotion, leaping and brachiation. They have long, bicolored tails and weigh an average of 6.0 kilograms. Males weigh only slightly more than females. Mitred leaf-monkeys are distinguished from other Presbytis species by their single-phrase call, pelage characters, and skull features such as long nasals and narrow interorbitals.
Presbytis melalophos has brownish-gray pelage with the ventral side lighter than the dorsum. The tail is bicolored and the head has a distinct black crest. There are four subspecies of Presbytis melalophos based on pelage differences, distinctions in vocalizations, and geographic location. P. m. bicolor is the whitest subspecies and P. m. sumatrana is the darkest subspecies. The pelage color of P. m. mitrata and P. m. sumatrana is intermediate. Neonates are white with a pale face and a dark, reddish-brown spinal stripe.
