Pseudomys australis Gray, 1832 . Proc. Zool. Soc. Lond., 1832:39.

TYPE LOCALITY: Australia, New South Wales, SW side of Liverpool Plains .

DISTRIBUTION: Australia; New South Wales, S Queensland, South Australia, and S Northern Territory; Late Pleistocene to Recent remains from W Victoria (Watts and Aslin, 1981); probably extinct in New South Wales (Mahoney and Richardson, 1988:172).

SYNONYMS: auritus, flavescens, lineolatus, minnie, murinus, stirtoni .

COMMENTS: Microscopic structure of hooks on sperm head reported by Flaherty and Breed (1982). Phallic information suggested P. australis is related to P. gouldii, P. higginsi, and P. nanus, to the exclusion of other species of Pseudomys (Lidicker and Brylski, 1987:635); electrophoretic data (Baverstock et al., 1981) and spermatozoal morphology (Breed, 1983) are not discordant with this association.
