May 2008. A gibbon subspecies from China’s Yunnan province has been declared extinct by a Chinese-Swiss research team. The white-handed, or lar gibbon, Hylobates lar, was last observed in 1988 in the Nangunhe Nature Reserve in south-western Yunnan province, and the loud, melodious calls of this species of ape were last heard in Yunnan in 1992.
