Capped langur  (Trachypithecus pileatus)

Small differences in colouration distinguish the four subspecies of capped langur, but the species as a whole is recognised by the dark grey to black fur of the back, fading to creamy white or golden yellow on the belly. Exceptions include T. p. durga, in which the belly, whiskers and throat are orange, and females of T. p. tenebricus, in which the belly is pale red. The face is black and the crown dark grey – darkest in T. p. tenebricus, and defined by a grey collar, and lightest in T. p. brahma. The cheeks have a yellow-red hue, and the ears, palms and soles are black. The rump and insides of the thighs are light blue, and this colouration is stronger in males than females. Infants are creamy-white with a soft golden tinge all over. The face, ears, palms and soles are pink; the face being darkest. Juveniles lose the glow of gold as they mature and begin to turn an ashy grey, and their bare skin turns from pink to black (3).
