FRANÇOIS' LANGUR
Presbytis francoisi
I also just recently discovered this monkey at the SF Zoo along with the cutest ever - Emperor Tamarin. Since I don't know very much about this critter, except that they stay high up in their cage which eliminates the chance for a decent photo. If they come down to the ground there is a vantage point that lets you shoot through glass instead of mesh screen. And so I only have this one shot so far.
