Saccostomus Peters, 1846 . Bericht Verhandl. K. Preuss. Akad. Wiss., Berlin, 11:258.

TYPE SPECIES: Saccostomus campestris Peters, 1846 .

SYNONYMS: Eosaccomys .

COMMENTS: Ellerman (1941) thought that all nominal forms would prove to be races of the single species S. campestris, a speculation widely observed in later classifications and faunal reports (e.g., Delany, 1975; Ellerman et al., 1953; Kingdon, 1974; Misonne, 1974). Hubert (1978a), however, presented karyotypic and morphological evidence that differentiates an eastern African species (S. mearnsi) from a southern African one ( S. campestris), as earlier intimated by Allen and Lawrence (1936).
