Abstract
Five new troglobitic species of the previously monotypic pseudoscorpion genus Austrohorus are described from subterranean habitats within the Pilbara bioregion of northern Western Australia. Austrohorus ferrugineus sp. nov. is the northernmost species, while A. buzzcocksi sp. nov., A. ineptus sp. nov., A. nativitatis sp. nov. and A. valentulus sp. nov. occur further east. The Austrohorus species exhibit morphological features consistent with Austrohorus exsul Beier, 1966, the first and only described species of the genus.
