Common Name(s):
English Heck's Macaque
Macaca tonkeana ssp. hecki (Matschie 1901)

It is known to occur in at least 6 protected areas: Dolangan Reserve, Mas Popaya Raja Reserve, Panua Reserve, Pangi Binanga Reserve, Pinjam/Tanjung Mantop Reserve, Tangale Reserve (M. Richardson pers. comm.). There is a need to expand existing protected areas. There are no specimens reported in captivity.
