Type Locality: Tanzania, Ukinga Mtns, north end of Lake Nyasa, Madehani, 7000 ft.

Vernacular Names: Tanzanian Vlei Rat.

Distribution: Isolated populations in mountains, ca. 1400-2300 m, of N Malawi, SC Tanzania (e.g., Stanley et al., 1998), and SW Kenya (Aberdare Range as per Taylor and Kumirai, 2001:Fig. 1).

Discussion: A distinctive form diagnosed as a subspecies of O. anchietae by its describers and thereafter placed in taxonomic compendia (Bohmann, 1952; Misonne, 1974; Musser and Carleton, 1993). Morphological contrasts noted and specific status reasserted by Dieterlen and Van der Straeten (1992); morphological and morphometric discrimination amplified by Taylor and Kimurai (2001).
