Sykes' monkey (Cercopithecus albogularis), also known as the white-throated monkey or Samango monkey, is an Old World monkey found between Ethiopia and South Africa, including south and east Democratic Republic of Congo. It is named after English naturalist Colonel William Henry Sykes (1790-1872), and has been considered conspecific with the blue monkey (which in turn has included the golden and silver monkey), but has a large white patch on the throat and upper chest, and a grizzled (not blackish) cap.
