Taxonomy & Nomenclature
Synonym/s: Notomys megalotis Iredale & Troughton, 1934
Last record: 19 July 1843 or later (Ride, 1970:202); 1843 (Kitchener et al., 1980)
IUCN RedList status: Extinct
The Big-eared hopping mouse (Notomys macrotis) is only known from two damaged specimens held in the British Museum. One of which was collected by John Gilbert on 19 July, 1843, near New Norcia in the Moore River region (Ride, 1970:202). The other lacks locality data, and was purchased by the BMNH from John Gould's personal collection (Ibid.). It may very well have been collected at roughly the same time by Gilbert.
The writings of John Gilbert list three local aboriginal names for this species (Abbott, 2001), demonstrating aboriginal knowledge of the species.
It seems to be entirely absent from subfossil collections from localities throughout WA (Burbidge et al., 2009), indicating that it was a restricted endemic. However, although the last record of the species is more than 150 years ago, there was little collecting activity coincident with its presumably small range until well into the 1900's (Burbidge & Woinarski, 2016). So it's extinction chronology is virtually unknown, with predation by feral cats presumed to be responsible for its extinction.
