 Serventy noted the species had disappeared from areas near Perth and Pinjarra by the mid-twentieth century, perhaps from the Swan Coastal Plain altogether, though it had persisted at gullies around Mundaring Weir in the Darling Range.The "Records" (1991) of the Western Australian Museum gave a northern most location of Glen Forrest in the Darling Range to an area near North Bannister and Mount Saddleback, and confirmed their continued absence from the Swan Coastal plain.However, there are occasional reports of sightings in the largely cleared region, HANZAB notes two seen at Canning Mills in 1997.
