A new species of macaque, Macaca munzala or the Arunachal macaque, has been discovered in northeastern India. This is an incredibly rare event—the last new macaque species was found 101 years ago, and it's been 49 years since any new primate was discovered in Asia. "Discovered" may be not quite the right word; the inhabitants of this region of India are entirely familiar with it, and have been shooting it for its habit of raiding crops, and apparently it is a thriving species found in multiple populations. It had so far escaped the notice of scientists, at any rate, since it lives in an out-of-the-way part of the world and resides at high altitudes, above 2000 m.
