A forest shrew of West Africa. Studies record it in lowland rainforest and place it in southeastern Guinea, eastern Liberia, and southwestern Côte d’Ivoire.
The diagnosis describes the fur and skin as uniformly dark in both C. obscurior and C. eburnea. This is not a distinguishing feature of C. eburnea alone.
In Taï National Park, this shrew occurs in both primary forest and secondary forest growing on former coffee and cocoa plantations.
Sampling in the western part of the park from March to June 2010 yielded two individuals in primary forest and five in secondary forest; none were captured in swamp forest. Researchers used traps in all three habitats and combined external measurements and genetic evidence for identification. The report counted this species separately from its similar relative, with which it had previously been confused.
An extinction-risk assessment has not been added yet.
In Taï National Park, where this shrew is documented, WCF continued conservation work with OIPR in 2024. Its report records ten community ecoguards patrolling a combined 344 kilometres.
