Species of Old World monkey
The Sarawak surili ,[ 1] Bornean banded langur ,[ 2] or cross-marked langur [ 3] (Presbytis chrysomelas ) is a species of primate in the family Cercopithecidae . It is endemic to the southeast Asian island of Borneo ,[ 1] [ 2] where it is distributed north of the Kapuas River in Kalimantan , Indonesia , the Malaysia states of Sarawak and Sabah , and in Brunei . Its taxonomy is complex and disputed,[ 4] and it has been considered a subspecies of P. femoralis or P. melalophos .[ 1] The Sarawak surili was formerly considered common, but has declined drastically due to persecution and habitat loss , and as of 2015 is only known from five sites with a combined population of 200–500 individuals.[ 2] Consequently, it is believed to be one of the rarest primates in the world, and has been rated as critically endangered by IUCN .[ 2]
