One new combination is made: A. arthrostyloides (W.Fitzg.) K.L.Clarke, K.L.Wilson & J.J.Bruhl. Several of these species have very restricted distributions and are of conservation concern. Two species also occur in the western Northern Territory. All of these taxa have previously been listed on Western Australia.s plant census under phrase names. All species are illustrated. A revised key to species of Actinoschoenus in the Kimberley region is provided.
