Kingdom Phylum Class Order Family

Scientific Name: Heimyscus fumosus (Brosset, DuBost & Heim de Balsac, 1965)
Common Name(s):
English African Smoky Mouse, Smokey Heimyscus
Taxonomic Notes: Comments from Musser and Carleton (2005): "Now thought to be a good species but originally described as a species of Hylomyscus, but differs significantly from any species in that genus in morphological and chromosomal traits (Misonne 1969; Robbins et al. 1980), ecology (Duplantier, 1989), and complete mitochondrial DNA cytochrome b sequences (Lecompte et al. 2002b). Chevret et al. (1994), however, suggested that the degree of nucleotide substitutions indicated fumosus could remain in Hylomyscus under subgenus Heimyscus."

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-09-01
Assessor(s): Granjon, L.
Reviewer(s): Amori, G.

Listed as Least Concern because, although the habitat is declining in the region due to the impacts of agriculture and deforestation, this species is still widely distributed in Central Africa. Its relative rarity at trapping is probably a reflection on the sampling techniques used.

Previously published Red List assessments:

Population [top]

Population:It is relatively uncommon and is usually trapped in fairly small numbers. This species does not enter traps easily which could possibly explain why they are perceived to be uncommon. They have been shown to be more abundant when trapped using pitfall traps.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is found in primary lowland forest. This is a habitat specialist and is not found in disturbed forests.
Generation Length (years):1-2

Threats [top]

Major Threat(s): This species is threatened by habitat loss through deforestation for both timber and wood, and for the conversion of land to subsistence agriculture close to villages.

Conservation Actions [top]

Conservation Actions: It occurs in protected areas in both Gabon and Equatorial Guinea.
