yes (Booted Macaque to most people) - what I was meaning is that I "think" I saw them at Ragunan but I'm not 100% sure because I didn't keep a list and they had several Sulawesi species.
I figured by "outside their natural range" you meant Indonesia rather than Sulawesi specifically, but nevertheless there are probably still a number of Indonesian zoos which keep them outside Sulawesi.
The new Zoo Grapevine & International Zoo News states that "the only known group of Booted Macaques outside Indonesia resides at the Catoctin Wildlife Preserve and Zoo in Thurmont, Maryland."
