White-cheeked Crested Gibbon
Encyclopedia
The northern white-cheeked gibbon (Nomascus leucogenys) is a species of gibbon
native to Vietnam
, Laos
, and the Yunnan
province of China. It is closely related to the southern white-cheeked gibbon
(Nomascus siki), with which it was previously considered conspecific. The females of the two species are virtually indistinguishable in appearance.
The genome of N. leucogenys was sequenced and published in 2011.
A "substantial" population of 455 critically endangered northern white-cheeked crested gibbons (Nomascus leucogenys) have been recently found living in the Pu Mat National Park
in Nghe An province, northern Vietnam, near the border with Laos. Conservation International
report they are living at high altitudes, and far from human settlements. This population, representing two thirds of the total known in Vietnam are, apparently, the "only confirmed viable population" of this variety in the world.
