The morphological variation in the Ebony and Silver leaf monkeys (Trachypithecus auratus and T. cristatus) from Southeast Asia, Thailand, Malaya, Bintan, Sumatra, Serasan-Natuna, Kalimantan and Java were studied using multivariate analysis approaches. The results showed that clonal variation in skull, dental and dentary morphology was found in Java. The skull, dental and dentary characters showed an increase from West to East with Central Java as an intermediate form. Consequently, in Java there should be only one subspecies, T. auratus. Meanwhile, there are four morphological groups of Trachipithecus cristatus, those are from Thailand, Malaya-Sumatra-Kalimantan, Bintan and Natuna. The Malayan population, presumably is the same as Bintan population while Sumatra-Kalimantan forms an intermediate
