Descriptive notes. There are no specific measurements available, but the West Javan Langur is probably similar to the East Javan Langur (7 auratus). Circumfacial hair of the West Javan Langur is erect and forward-curled, facial skin is bluish or blackish, and ears have whitish or yellowish tufts. Females differ from males in having a pale, usually yellowish-white, pubic patch. Jaws and teeth are notably large. Palms and soles are slaty-black. Fur is glossy-black, with a very slight brownish tinge, especially on belly, sideburns, and legs. The West Javan Langur is generally similar to the “ black ” morph of the East Javan Langur, but it lacks the light-tipped hairs.
