|Scientific Name:||Cephalophus jentinki|
|Species Authority:||Thomas, 1892|
|Taxonomic Notes:||Monotypic. Analysis of mtDNA showed it was closest to Cephalophus dorsalis and more distantly related to C. spadix and C. silvicultor (van Vuuren and Robinson 2001).|
|Red List Category & Criteria:||Endangered C1 ver 3.1|
|Assessor(s):||IUCN SSC Antelope Specialist Group|
|Reviewer(s):||Hoffmann, M. & Mallon, D.|
Listed as Endangered as there are estimated to be fewer than 2,500 mature individuals (total population may be <2,000) and a 20% decline over two generations (12.6 years) is estimated due to loss of primary forest cover and intensive poaching and snaring in many parts of the range.

|Range Description:||Confined to the western part of the Upper Guinea Forest, from Sierra Leone through Liberia to the Niouniourou river in western Côte d’Ivoire (East 1999, Hoppe-Dominik 2013) and in south-eastern Guinea (Bützler 1994, Brugière 2012).|
In Sierra Leone it was positively reported for the first time in 1989 in the Western Area Forest Reserve, the southern part of the Freetown Peninsula, adjacent to the capital city, Freetown (Davies and Birkenhager 1990). Camera trap evidence has shown that it is still present there (Garriga and McKenna 2014). They have also recently been photographed in Gola Rainforest National Park (Ganas and Lindsell 2010) and are previously reported in the Mokanji Hills, Loma Mountains, and Tingi Hills (Hoppe-Dominik 2013).
Occurred widely in eastern Liberia, along the Sehnkwehn River, the Sinoe river and Buto Oil Palm Plantation (Kranz and Glumac 1983). It is present in Sapo NP (Vogt 2011) and has been recorded in Grebo National Forest and Krahn-Bassa National Forest (Hoppe-Dominik 2013).
In Côte d’Ivoire its stronghold is in Taï National Park in the south-west, and adjacent and the nearby Haut Dodo, Rapid Grah, Cavally-Gouin and Scio Classified Forests (Hoope-Dominik 2013).
Distribution in Guinea is restricted to the far south-east, it has been recorded in Ziama Biosphere Reserve and Diécké Forest (Bützler 1994) and Mont Nimba Strict Nature Reserve (Brugière 2012).

|Population:||This large duiker appears to be very uncommon/rare throughout its range. East (1999) assumed a mean density of 0.1/km2 and produced a total population estimate of about 3,500, but Wilson (2001) doubted whether even more than 2,000 animals remained. The population trend is downwards except perhaps for a few areas where forest destruction and hunting pressures are lower and where there is effective protection: e.g. Sapo National Park, Gola Rainforest NP, the western section of Taï National Park (Hoppe-Dominik 2013).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Jentink’s Duiker occurs predominantly in primary high forest, but it may enter adjacent secondary growth, plantations and farmbush (East 1999, Wilson 2001). Its most basic requirements appear to be a diversity of fruiting trees and very dense shelter rather than a specific forest type (Kingdon 1997).|
Feeds on many fruits, including those with hard shells, nuts, stems of tree seedlings and may consume cocoa pods, mangoes and palm nuts in plantations (Hoppe-Dominik 2013).
|Generation Length (years):||6.3|
|Use and Trade:||Hunted for bushmeat; such hunting, especially using cable snares is increasing across West Africa. A market examination of a stand in the east of Taï National Park counted about 3.3% Jentink's Duiker, and Jentink's are poached in both the east and west of the park (Hoppe-Dominik 2013).|
|Major Threat(s):||The major threats to this species are widespread forest destruction (due to, for example, logging and agricultural expansion) and hunting for meat. The influence of hunting on this species is considerable (Caspary et al. 1999, Hoppe-Dominik 2013).|
|Conservation Actions:||Listed on CITES Appendix I. The long-term survival of Jentink’s Duiker is closely linked to effective protection in the remaining blocks of primary forest, in particular Taï NP, Cavally-Gouin and other forest reserves in Côte d'Ivoire; Sapo NP, Gola, Grebo Krahn-Bassa, and Senkwehn National Forests in Liberia (all of which are proposed national parks); Western Area Forest Reserve and Gola Rainforest NP in Sierra Leone, and Ziama Biosphere Reserve in Guinea. Mount Nimba is also likely to be an important site.|
