Newly discovered / described species 2015

A new species of macaque, called the white-cheeked macaque Macaca leucogenys has been discovered after having previously been identified as Assamese macaques.

The new species lives in Tibet, and has unique morphological characteristics such as prominent white whiskers on the cheeks and chin, thick neck hair, a short-furred tail and round instead of arrow-shaped genitalia in the males. They also have a distinct alarm call.

The species is thought to already be threatened due to habitat destruction.

I'm quite surprised, even shocked, that a new species is being described based solely on camera trap photos. As far as I can tell, no-one has actually laid eyes on this macaque. I'm not saying that this is not an actual species, but I'd definitely like to see some genetic or morphological evidence on it, rather than descriptions of white hair on its face and a differently shaped penis based just on photos. It shouldn't be that hard to get such physical evidence, and should be do-able without killing any macaques.
