The macaques are heavily built, old-world monkeys, characterised by strong limbs of equal length and moderately long snouts (4) (5) (6). The island of Sulawesi in Indonesia is home to a unique radiation of macaques, with between four to seven described species (depending on the accepted taxonomic status) occurring in an area that represents just one percent of the total range of all macaque species (6). One of these endemics is the booted macaque, a species comprising two geographically separated subspecies, one of which, the Buton macaque (Macaca ochreata brunnescens), is sometimes treated as a separate species, Macaca brunnescens (1) (4) (6). However, many researchers consider the differences between the two subspecies to be too slight to warrant their separation (1) (6). Indeed, the two booted macaque subspecies are very similar in appearance, and can be distinguished from other Sulawesi species by having blackish torsos that contrast with characteristic grey limbs (2) (6) (7). The subtle differences that distinguish M. o. brunnescens from M. o. ochreata are largely limited to the former’s shorter, browner pelage and shorter face (6). In common with all Sulawesi macaques, both subspecies have very short tails, and adult males are significantly larger than adult females (2) (6).
