5 October 2009 - Jozani Forest (Jozani-Chwaka Bay National Park), Zanzibar, Tanzania.

Sykes' Monkey or White-throated Monkey / Witkeelmeerkat (Cercopithecus albogularis), subspecies: Zanzibar Sykes' Monkey / Zanzibar Witkeelmeerkat (Cercopithecus albogularis albogularis).

Subspecies Zanzibar Sykes' Monkey is also known as Cercopithecus mitis albogularis.

There is some dispute about the classification: is this Blue Monkey from Zanzibar a species (if so, what species, C. mitis or C. albogularis?) or a subspecies (C. m. albogularis or C. a. albogularis?). If anybody has an conclusive answer, please leave a comment.
