Semnopithecus vetulus nestor. The Zoo has kept and bred this subspecies for well over a decade, but they have never been on display. Sadly the captive population was not sustainable and this female is the last of the subspecies at the Zoo (and possibly in captivity?). She is now integrated with the free-ranging Javan Langurs at Primate Kingdom.
@Nix the langurs are not kept in an enclosure and are free to wander the Zoo grounds as they wish. They are still fed by their keepers and are conditioned to return to their night quarters daily.
I believe Induna Primate and Parrot Park in South Africa, Chimelong Safari Park in China and Chiba Zoological Park in Japan, still house Purple-faced langur. I'm not too sure about the western subspecies specifically but they are still around in collections outside Sri Lanka. Additionally Nix did find a picture of relatively young hybrid langur which I believe could possibly be part Purple-faced langur in South Africa.
@Kestrel The possible Hybrid individual is kept at Monkeyland in Plettenberg bay area of South Africa, additionally a pure individual exists or existed at Eventieria Wildlife Park in the Vaalwater area of the Limpopo Province, the last photographic evidence of this individual still being alive is from early 2021, so she might have past on since then.
@Nix I hope and pray that there are more, since (afaik) Induna and Eventieria are private zoos you never know how many they could actually have, but the chances are that the only breeding troop is at Chimelong.
