Crossarchus platycephalus


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Crossarchus platycephalus
Species Authority: Goldman, 1984
Common Name/s:
English Cameroon Cusimanse, Flat-headed Cusimanse
Taxonomic Notes: Considered conspecific with Crossarchus obscurus 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). See Wozencraft (2005) and Goldman (in press) for further discussion.

Goldman (1984), separated central (C. platycephalus) from western (C. obscurus) African populations based on phenetic differences in skull proportions. Wozencraft (1989) argued for consideration of these populations as conspecific. Reviewed by Goldman (1987). The separation of C. platycephalus from C. obscurus has been generally supported by others (Colyn and Van Rompaey 1994).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Goldman, C. & Hoffmann, M.
Reviewer/s: Duckworth, J.W. (Small Carnivore Red List Authority) and Hoffmann, M. (Global Mammal Assessment Team)
Listed as Least Concern as the species is relatively widespread, and possibly adaptable to somewhat disturbed habitats, there are no known major threats, and it is present in several protected areas.

Geographic Range [top]

Range Description: Occurs in rainforests of Benin, Nigeria, Cameroon, Equatorial Guinea, Congo Republic, and Central African Republic (Goldman in press). The specific locality of a specimen collected in Benin is uncertain and given as “Agouagou?”, which is well beyond the rainforest zone (Goldman in press). Not yet recorded from the rainforests of Gabon, but probably occurs. Ranges from sea level to ca. 1,600 m asl.
Cameroon; Central African Republic; Congo; Equatorial Guinea; Nigeria

Population [top]

Population: Although relatively widely distributed, they are probably not common anywhere in their range.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Found in undergrowth of rainforest, often near water. In Nigeria, they have been recorded in areas of fragmented forest mixed with farmland (Angelici et al. 1999) and as widespread in the Niger Delta, including the largely deforested lowland zone east of Orashi R. (Powell 1997).
Systems: Terrestrial

Threats [top]

Major Threat(s): No major threats, but, like other species of cusimanses, they are hunted for bushmeat (e.g., Juste et al. 1995).

Conservation Actions [top]

Conservation Actions: Present in several protected areas, including Monte Alen N.P. in Equatorial Guinea and Dzanga-Sangha Reserve in Central African Republic (Goldman in press).
