Arunachal macaque Arunachal macaque The Arunachal macaque ("Macaca munzala"), a relatively large brown primate with a comparatively short tail, is a macaque native to Arunachal Pradesh in northeastern India. Its species name comes from "munzala" ("monkey of the deep forest") as it was called by the Dirang Monpa tribe. It was discovered as a new taxon in 1997 by the noted Indian primatologist Anwaruddin Choudhury, but he thought it to be a new subspecies of Tibetan (or Père David's) macaque. It was described as a new species in 2004, when a group of scientists from the Nature Conservation Foundation, India reported it.
White-cheeked macaque the animals caught on tape (including more prominent whiskers, thicker neck hair, and differences in the shape of the genitalia), primatologists in China declared them to be a new species. Their research, along with a series of photographs of the species, was published in the July 2015 issue of the "American Journal of Primatology". In April 2016, a group of wildlife photographers and biologists spotted and photographed the white-cheeked macaque in Arunachal Pradesh, India. Prior to this sighting, the species was thought to exist only in Tibet. Physiologically, the white-cheeked macaque is similar to the other members of the genus
