Status and Conservation. CITES Appendix II. Classified as Vulnerable on The IUCN Red List (as 1. auratus auratus). The EastJavan Langur has been protected by Indonesian law since 1999. Although still widely distributed, populations are reduced and fragmented. General habitat loss and degradation due to agriculture and human settlements are major threats, as are hunting for food and the pet trade. It occurs in at least seven protected areas in Indonesia: Alas Purwo, Bali Barat, Baluran, BromoTengger Semeru, Gunung Merapi, and Meru Betiri national parks and Pangandaran Nature Reserve.

Descriptive notes. Head-body 44 - 65 cm (males), tail 61 - 87 cm (males); weight c. 7 - 1 kg (males); no measurements are available for females. The EastJavan Langur is a large and extraordinarily beautiful monkey. Its circumfacial hair is erect and forwardcurled, 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. There are two main color morphs; the more common is glossy-black, with a slight brownish tinge (particularly on belly, sideburns, and legs). Its hairs are light-tipped on arms, legs, head, flanks, and sometimes back. Palms, soles, and facial skin are slaty-black. The much rarer “ red ” morph is restricted to an area between Blitar, [jen, and Pugeran. It is deep orange, becoming more yellowish on limbs, ears, and belly. There is often a black fringe on its dorsum, and its palms, soles, and facial skin are depigmented or freckled.
