A specimen of the Triodia Earless Skink Hemiergis millewae was discovered on the Barrier Range of far-western New South Wales (NSW). This observation is significant because it constitutes the first record of the species in NSW and the Broken Hill Complex bioregion, extending the species’ range 140 km north-east of the nearest known population in South Australia. Suitable spinifex habitat for H. millewae is highly isolated and small in extent on the Barrier Range, and the species may qualify for listing as a threatened species in NSW. I discuss the cause of apparent disjunctions in the species’ distribution and highlight the need for additional survey effort.
