A new genus and species of Antarcturidae, Marmachius fortunae, is described from the bathyal of south-eastern Australia.Antarcturus, type genus of the family, and Marmachius are diagnosed. The new genus differs from other antarcturidgenera by the combination of the possession of middorsal spines, extremely long spines generally, free pleonite 1, and thegroove on the exopod of the male pleopod 1 opening distolaterally on a lobe-like apex beset with numerous fine setae. Antarcturus princeps is transferred to the new genus.
