Abstract
Two new species of the extinct macropodid genus Sthenurus are described from vertebrate deposits in eastern and northeastern New South Wales. Although its exact stratigraphic origin is uncertain, Sthenurus brachyselenis sp. nov. displays an early stage of evolution, only slightly more derived than the plesiomorphic early Pliocene S. cegsai. Its molars are low crowned and relatively simple, and P3 bears a very short buccal crest. S. euryskaphus sp. nov. is from the Pleistocene Bingara deposit and is morphologically intermediate between the late Pliocene S. antiquus and two widespread Pleistocene species. S. areas, within which the two new species were previously included, is deemed to be a very derived member of the genus, and may reside phylogenetically close to the origin of Procoptodon.
