Wikipedia Abstract

The Javan lutung (Trachypithecus auratus), also known as the ebony lutung and Javan langur, is an Old World monkey from the Colobinae subfamily. It is most commonly glossy black with a brownish tinge to its legs, sides, and "sideburns". It is found on and endemic to the island of Java, as well as on several of the surrounding Indonesian islands. The Latin word auratus in its scientific name means "golden", and refers to a less common color variant. Note that the common name golden langur is used for a different species.
