Taxonomic Notes: Although formerly included in the genus Aethomys, chromosomal, morphological and molecular evidence support the recognition of Micaelamys as a distinct genus (Baker et al. 1988, Russo 2003, Chimimba 2005, Lecompte et al. 2008). Micaelamys granti can be can be distinguished from M. namaquensis on morphological and chromosomal grounds (Visser and Robinson 1986, 1987; Chimimba et al. 1999). In M. namaquensis the tail is relatively longer, the ventral pelage is often pure white, and there are only three pairs of nipples; whereas, in M. granti, the ventral pelage is never pure white (usually grey or greyish), and there are five pairs of nipples (Monadjem et al. 2015).
