Pseudomys auritus Thomas, 1910

Long-eared mouse, Long-eared pseudo-rat



Taxonomy & Nomenclature

Synonym/s: Pseudomys australis auritus Thomas, 1910

Sometimes regarded as a junior synonym of P. australis (e.g. Musser & Carleton, 2005). However, it is likely a valid species according to (Medlin, 2008). So there is at least some taxonomic dispute to be resolved.
