The identity of the spider shown on this page is uncertain, although its general appearance, and especially its oval and inwards-leaning posterior median eyes, strongly suggests it is a gnaphosid. It seems to have much in common with the better known Anzacia species. However, there are on the internet and in Whyte and Anderson's 2017 "A Field Guide to Spiders of Australia" book several photos that are labelled Encoptarthria and that resemble those shown above, and Encoptarthria species have been recorded in Tasmania and Western Australia and are suggested to have a much wider distribution in this country.
