Belfast Zoo, Port Lymnpe Wild Animal Park and Cotswold Wildlife Park all keep Verreux's Sifaka. The Latter has one male, PL has two males, and Belfast has four males and one female.
All UK sifakas are crowned sifakas (Propithecus verreauxi coronatus). This is a subspecies of Verreaux's Sifaka.
Isn't the crowned sifaka now classified as a species in their own right (Propithecus coronatus)? @ BearCat: The golden-crowned sifaka is a critically endangered species of sifaka (different to the crowned sifaka). There are thought to be fewer than 300 individuals left. The last captive animal died last year at the Duke Lemur Centre. It has a very small range, little of which is in protected areas. Following recent political instability in Madagascar, military activity in their home range as well as desperate hunting for bushmeat leaves this fantastic species facing an extremely uncertain future.
Port Lympne did receive a pair of sifakas from Paris last year but unfortunately the female died not long after arrival .
coronatus has been considered a subspecies both of verreauxi and later deckenii -- which itself was formerly considered a subspecies of verreauxi!! In 2002 it was first suggested that coronatus deserved species status, a thought more recently (2007) supported by craniometric studies which found it to have highly distinctive cranial features. The trend in taxonomy nowadays of course is towards rampant splitting of pretty much any taxa you can think of
