Acomys ignitus Dollman, 1910 . Ann. Mag. Nat. Hist., ser. 8, 6:229.

TYPE LOCALITY: Kenya, Voi .

DISTRIBUTION: Usambara Mtns in NE Tanzania (specimens in Field Museum of Natural History), and Kenya; limits unknown.

COMMENTS: Subgenus Acomys . Petter (1983) recognized ignitus as a valid species, clashing with Setzer (1975), who regarded it as part of A. dimidiatus . Petter's action reflects reality, reinforcing Hollister (1919) and Ellerman (1941), who recognized ignitus as a distinct species, but associated the names pulchellus, kempi, and nwntanus with it either as subspecies or direct synonyms. Janecek et al. (1991) considered ignitus distinct and phylogenetically closely related to A. cahirinus, based on genic data.
