Overview

Distribution

Range Description

Endemic to West Africa, and confirmed only in south-western Côte d’Ivoire, where known from two records, and in eastern Liberia, where there are several records (Van Rompaey and Colyn in press). The presence of this species in the Kounounkan Massif in south-western Guinea (Barnett et al. 1996) requires confirmation (Van Rompaey and Colyn in press). There is no confirmed record of the species from Sierra Leone.

Justification
There is no current information on the population status of this species (there are no records since the late 1908s), its limits of distribution are not well known, and it is unclear to what degree it is impacted by hunting. The core of its range is centred on an area known to be at risk of habitat loss (although rates of forest loss are lower in Liberia than neighbouring Côte d’Ivoire), to which this arboreal species is susceptible, but it is unlikely that the rate of forest loss alone has been sufficient over a 10-year period to warrant listing in a threatened category. In the absence of additional information on threats (specifically its susceptibility to hunting) and current population status, it is provisionally listed as Data Deficient.

Population

Population
There is no reliable information on the population status of this species, with the most recent confirmed records from Liberia in the late 1980s (Taylor 1992). Apparently rare and very localized (Rosevear 1974).

Threats

Major Threats
Major threats to this species are not known, but like Johnston's Genet Genetta johnstoni and Liberian Mongoose Liberiictis kuhni the species is probably being affected by ongoing habitat loss in the upper Guinean forests, probably more so given that it is a canopy species. It is unclear to what degree this semi-arboreal species is impacted by bushmeat hunting, but this may well be a threat.

Management

Conservation Actions

Conservation Actions
It may occur in the Sangbé N.P. in Côte d’Ivoire (Hoppe-Dominik 1990) and the type locality is not far away from the northern boundary of Liberia’s Sapo N.P. (Schreiber et al. 1989). This is a priority species for further survey work, particularly to better determine its current range and population status, whether or not it is subject to hunting, and to investigate other aspects of its ecology.
