Noordelijke geelwang-kuifgibbons blijken aparte soort en zijn nu de zeldzaamste apen op aarde

This undated recent handout picture taken in Vietnam and released on September 21, 2010 by the German Primate Center (DPZ) shows a female northern buffed-cheeked gibbon. German scientists said they had discovered a new rare and endangered ape species in the tropical rainforests between Vietnam, Laos and Cambodia by its distinctive song. The new type of crested gibbon, one of the most endangered primate species in the world, is called the northern buffed-cheeked gibbon or Nomascus annamensis, a statement from the German Primate Centre (DPZ) said.
