SPECIES Otomys saundersiae

Author:Roberts, 1929.
Citation:Ann. Transvaal Mus., 13: 115.
Common Name:Saunders’ Vlei Rat
Type Locality:South Africa, Eastern Cape Province, Grahamstown.
Distribution:Isolated populations in Western Cape, Eastern Cape, and Free State provinces, South Africa, and in Lesotho.
Status:IUCN – Lower Risk (lc).
Comments:Roberts (1929) named saundersiae as a subspecies of tugelensis (= O. angoniensis) but later (1951) raised it to full species, as commonly recognized in the literature (e.g., Corbet and Hill, 1991; De Graaff, 1981; Ellerman and Morrison-Scott, 1953; Misonne, 1974; Meester et al., 1986). The form karoensis, in Western Cape Province, has been variously treated as a species (G. M. Allen, 1939; Bohmann, 1952; Roberts, 1931; Taylor et al., 1993) or as a distinctive subspecies of O. saundersiae (Roberts, 1951; Taylor et al., in prep.). Taylor et al. (1993, as karoensis; in prep.) provided morphological bases for discrimination of O. saundersiae from O. irroratus, evaluated geographic and nongeographic variation, and contrasted G-banded karyotypes. The apparent rarity of O. saundersiae populations in the region of its type locality, Eastern Cape Province, is discussed by Taylor et al. (in prep.).
