The gray-legged langur duke ( Pygathrix cinerea Nadler,1997 ) is an extremely rare primate common only in the Central Highlands of Vietnam;it is one of the 25 most endangered species of primates in the world.Like the other langur duke,also the gray-legged one is one of the most vivid Primates,with almond-shaped eyes and a white mouth surrounded by a facial skin area varying in color from yellow-orange to light brown,and a band of white hairs that surround the sides of the head up to the ears.A large black band is present on the forehead and a series of white whiskers,up to 12 cm long,protrude considerably from the sides of the head.The various species of langur duke are distinguished by their color especially of the legs,and the gray-legged langur,of course,is identified by the dark gray color of the limbs,as well as by the top of the head,the back and the upper limbs light gray,and for the white tail,almost as long as the rest of the body and ending with a thin tuft.The color of the belly varies from light gray to almost white,the toes and feet are black,and the throat is white with an orange ring around the neck.
