Carpenter's lar gibbon

Carpenter's lar gibbon, Hylobates lar carpenteri, is a subspecies of the white-handed or lar gibbon that lives in northern and part of northeastern Thailand. It is listed as endangered because its population is believed to have fallen by more than half over three generations through the loss of forest habitat and the hunting of mature animals. The subspecies occurs in two sharply distinct colour forms. The dark form is very dark chocolate brown with blackish hair tips and silvery-brown hair bases, while the light form is creamy white with light grey bases. Both forms have a ring of white hair around the face and white hands and feet, sometimes reaching the wrists and ankles, and the hair is much longer than in other subspecies. In the southwest of its range it meets the range of the pileated gibbon. The subspecies name honours the primatologist Clarence R. Carpenter.
