%X Allopatric populations of the pseudomyine rodents Pseudomys albocinereus, P. delicatulus, the P. nanus-P. gracilicaudatus complex, Zyzomys argurus and Mesembriomys gouldi were surveyed for electrophoretic variability of 14-17 red cell and plasma proteins. Few or no electrophoretic differences were found to parallel the chromosomal differences between populations of P. delicatulus, Z. argurus, and M. gouldi. Populations of the P. nanus-P. gracilicaudatus complex, however, fell into two groups defined both chromosomally and electrophoretically. The western form (P. nanus) extends from Western Australia into the Northern Territory whilst the eastern form (P. gracilicaudatus) occurs only along the east coast of Queensland and New South Wales. The biochemical differentiation between South Australian, Western Australian mainland and Bernier Island P. albocinereus parallels the chromosomal, morphological and breeding data, all of which indicate that the Western Australian mainland and Bernier Island forms belong to one species (P. albocinereus), whilst the South Australian form represents a distinct biological species (P. apodemoides).
