Heimyscus fumosus (Brosset, Dubost, and Heim de Balsac 1965)

[Hylomyscus] fumosus Brosset, Dubost, and Heim de Balsac 1965, Biologia Gabonica, 1: 154.

Type Locality: Gabon, Makokou.

Vernacular Names: Smokey Heimyscus.

Distribution: Recorded only from the type locality, S Cameroon (Robbins et al., 1980), SW Gabon (specimens in FMNH, USNM), Republic of Congo (Granjon, 1991), and S Central African Republic (F. Petter and Genest, 1970; Malcom and Ray, 2000).

Conservation: IUCN – Lower Risk (lc).

Discussion: 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 mtDNA cytochrome b sequences (Lecompte et al., 2002 b). Chevret et al. (1994), however, suggested that the degree of nucleotide substitutions indicated fumosus could remain in Hylomyscus under subgenus Heimyscus . Chromosomal traits (2n = 40, FNa = 48) described by Lecompte (2003).
