||Modern taxonomic arrangements of the colobus monkeys either divide the red colobus and the Olive Colobus into two genera, Piliocolobus and Procolobus, respectively (e.g., Kingdon 1997, Groves 2005), or consider them to belong to one genus, Procolobus, with two subgenera (Procolobus for the Olive Colobus and Piliocolubus for the red colobus) (Grubb et al. 2003 [followed in the 2008 IUCN Red List], Grubb et al. 2013). The arrangement of using two separate genera in Groves (2001, 2005, 2007) is followed here.
This is an updated assessment to reflect the change in genus name.
|Red List Category & Criteria:
||Struhsaker, T. & Siex, K.
||Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Listed as Endangered as this species has an extent of occurrence <5,000 km² (probably <760 km²), there is severe fragmentation and continuing decline in area of occupancy, habitat, and the number of mature individuals.
|Previously published Red List assessments:|
- 2008 – Endangered (EN)
- 2000 – Endangered (EN)
- 1996 – Endangered (EN)
- 1994 – Endangered (E)
- 1990 – Endangered (E)
- 1988 – Endangered (E)

- 1965 – Very rare and believed to be decreasing in numbers
|Range Description:||This species is endemic to Zanzibar Island where it occurs at elevations of 0-110 m (Siex and Struhsaker 2013). Zanzibar Red Colobus may once have occurred on the mainland (as, for example, does Aders' Duiker Cephalophus adersi), but is certainly extirpated there now. On Zanzibar, it is found mainly in the south-eastern part of the island in Jozani-Chwaka Bay National Park, the adjacent agricultural areas to the south, and the coral thickets and mangrove swamps of Uzi Island 10 km to the south-west. Also found at low densities in isolated populations in the coral thickets along Zanzibar’s eastern coast from Kiwengwa in the north to Mnyambiji in the south, and on the west coast there is a small isolated group in the mangrove swamps of Maji Mekundu. A small translocated population of ca. 56 individuals also occurs in Masingini Forest Reserve (Siex and Struhsaker 2013). |
Approximately 14 animals were introduced to Ngezi Forest Reserve, Pemba Island, around 1974 (Struhsaker and Siex 1998: Oryx), where the species is believed to persist in small numbers (Camperio Ciani et al. 2001).
