Sarawak surili

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]
