The Southern Pig-tailed Macaque (Macaca nemestrina) is a medium-sized Old World monkey found in the southern half of the Thai-Malay Peninsula (only just extending into southernmost Thailand), Borneo, Sumatra and Bangka Island. This omnivorous macaque is mostly found in forest, but will also enter plantations and gardens. It formerly included the Northern Pig-tailed, Pagai Island, and Siberut Macaques as subspecies.
