(Dollman, 1912)
Tonkin snub-nosed langur range The Tonkin snub-nosed monkey or Dollman's snub-nosed monkey (Rhinopithecus avunculus) is a species of colobine endemic to northwestern Vietnam.[1]
Sightings of the Tonkin snub-nosed monkey have become increasingly rare. The primate was thought to be extinct until the 1990s when a small population was discovered in Na Hang District in Tuyen Quang Province of Vietnam. Heavy poaching for food as well as the wildlife blackmarket and the destruction of habitat are the main reasons why the Tonkin snub-nosed monkey is considered to be one of "The World's 25 Most Endangered Primates."[3][4]
By 2008, when a small population with three infants was discovered in a remote forest, fewer than 250 of the primates were thought to exist.[5]
