A new species, Meiogyne angurugensis M.-F.Liu, G.A.Wood & Junhao Chen, is described from Groot Eylandt. It is most similar to Meiogyne heteropetala (F.Muell.) D.C.Thomas, Chaowasku & R.M.K.Saunders, but differs in the number of the carpel per flower, the size of the perianth, and the outer petal aestivation. A key to Meiogyne species in Australia is presented.
