The pig-tailed macaque, Macaca nemestrina, which are distributed in Peninsular Malaysia, Thailand, Borneo, and Sumatra has been the subject of unstable and changing taxonomic entity in the M. nemestrina group. This species is involved with a human-macaque conflict in Malaysia and at the same time played important role in ethnozoological culture of Malaysian. Even so, comprehensive phylogenetic, population genetic, and biogeographical analysis of M. nemestrina in Malaysia are non-existent after decades of intensive research on the genus itself. Thus, we conducted the first comprehensive genetic study of M. nemestrina in Peninsular Malaysia and Malaysian Borneo, based on three mitochondrial loci, Cytochrome b (567 bp), D-loop (398 bp), and COI (577 bp) from 27 individual representing Malaysia, adding further 26 sequences of Southeast Asian macaques from Genbank. Comparative biogeographical analysis in this study supports the positions of M. nemestrina in M. nemestrina groups as opposed to silenus or Sulawesi groups. Results from this study also indicate that Bornean populations are the first extant lineages to separate as compared to other examined lineages of M. nemestrina, M. leonina, M. pagensis, and M. siberu in Southeast Asia. Molecular clock analysis suggested that M. nemestrina arrived in Malay Peninsula about 0.32 million years ago (MYA). Our results indicate that the population of pig-tailed macaque from Perak (west Peninsular Malaysia) differs genetically based on all phylogenetic and population genetic analyses. Morphologically, Perak’s pig-tailed macaque shows brighter coloration as compared to M. n. nemestrina. Thus, we proposed a new subspecies for Perak’s pig-tailed macaque as Macaca nemestrina perakensis distributed in state of Perak, Peninsular Malaysia. This research contributes to resolve the taxonomic position and population genetics of pig-tailed macaque in Malaysia, which contribute directly to conservation and management of the species in Malaysia.
