Lesula: Brand New Monkey Species "Discovered"

So they "discovered" a brand new monkey species.  I suppose "discovered" is an odd word since it is in the Congo, and the locals knew about them.
.
In fact, one that they investigated was in a classroom in the Congo - but it was undocumented hence "newly discovered".
.
It's yellow fur makes it always look out of focus to me.
