Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Van Rompaey, H. & Hoffmann, M.
Reviewer(s): Duckworth, J.W. (Small Carnivore Red List Authority) and Hoffmann, M. (Global Mammal Assessment Team)
Listed as Data Deficient as there is little information on the population status, distribution limits and threats to this species. It is likely that with further survey work the species will be shown to warrant listing as Least Concern, but in the absence of more reliable information it is provisionally listed as Data Deficient.

Geographic Range [top]

Range Description: Found only in Angola and DR Congo. In Angola, known only from a single specimen collected in 1908 north of the Cuanza R. (Crawford-Cabral 1989). In DR Congo, present in the rainforest south-east of the Congo/Lualaba Rivers (Van Rompaey and Colyn in press).

Population [top]

Population: Up until 1984, known only from two specimens, the type and the specimen from Baringa. However, they have since been found to be quite common in some regions (Van Rompaey and Colyn in press). During bushmeat surveys conducted in the eastern Congo basin, this species accounted for only 10% of carnivores compared with 42% for Alexander's Cusimanse (Colyn et al. 1987).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: An inhabitant of deciduous rainforest; not known to visit cultivated or inhabited land (Van Rompaey and Colyn in press).
Systems: Terrestrial

Threats [top]

Major Threat(s): Threats to this species are not clear, but they probably include habitat loss and bushmeat hunting.

Conservation Actions [top]

Conservation Actions: Recorded from Salonga N.P. in DR Congo. There is a paucity of information available for this species, making it a priority for research, particularly to determine its current population status and the extent of its range. In particular, a survey for the disjunct population in Angola is urgently needed where it is known only from the holotype (Van Rompaey and Colyn in press).
