Grammomys ibeanus (Osgood, 1910) . Field Mus. Nat. Hist. Pubi., Zool. Ser., 10:8.
TYPE LOCALITY: Kenya, Molo.
DISTRIBUTION: From extreme NE Zambia (Ansell, 1978) and Malawi (Ansell and Dowsett, 1988) north through SC Tanzania (specimens in Museum of Comparative Zoology, Harvard) and Kenya to S Sudan (Hollister, 1919; Hutterer and Dieterlen, 1984).
COMMENTS: Morphological and geographic definition of G. ibeanus is unsatisfactory, particularly the extent of its distribution in Tanzania. Hutterer and Dieterlen (1984) treated ibeanus as a form of G. cometes, but the striking morphological distinctions between samples of ibeanus and the type series of cometes prompted our specific ranking of ibeanus (see also account of G. cometes).
