|Scientific Name:||Crossarchus obscurus F.G. Cuvier, 1825|
|Taxonomic Notes:||Considered conspecific with Crossarchus platycephalus by Wozencraft (1993), but here treated as a distinct species following Van Rompaey and Colyn (1992), Colyn and Van Rompaey (1994) and Colyn et al. (1995). The separation of C. obscurus from C. platycephalus has been supported by a recent exhaustive study based on craniometric and molecular analyses (Sonet et al. 2014).|
|Red List Category & Criteria:||Least Concern ver 3.1|

This species is listed as Least Concern as it is relatively widely distributed in a variety of habitats, fairly common, and present in several protected areas.
|Previously published Red List assessments:|
|Range Description:||This species is restricted to the rainforests of southwest and southeast Guinea, Sierra Leone, Liberia, Côte d’Ivoire and Ghana, and extending just east of R. Volta (Goldman and Dunham 2013). It ranges from sea level to around 1,000 m asl in Sierra Leone (Gilchrist et al. 2009) and 1,500 m asl on Mt Nimba in Guinea (Goldman and Dunham 2013).|

|Population:||It is common. Population density in riparian forest of Taï N. P. was estimated at 13.2 individuals/km2 (Goldman and Dunham 2013).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is found primarily in dense undergrowth of rainforest, but also in farm bush, logged forest and plantations. In Côte d’Ivoire, it is also found in humid savanna zone, and in gallery forests of savanna, and in Ghana found on the Accra Plain (observed foraging in a dry open area of grassland and thicket; Goldman and Dunham 2013).|
|Generation Length (years):||4|
|Use and Trade:||It is used as bushmeat.|
|Major Threat(s):||There are no major threats, but it may be vulnerable to hunting in some regions (e.g., Guinea, where it was one of the most commonly trapped small carnivores; Colyn et al. 2004).|
|Conservation Actions:||It is present in several protected areas across the range, including Mt Sangbé, Maraouhé and Comoé National Parks in Côte d’Ivoire and Western Area Forest Reserve in Sierra Leone (Goldman and Dunham 2013).|
