| Abstract: | The type-species of the genus Xenocheira Haswell, X. fasciata Haswell, is redescribed (including the true male) from Tasmanian material. Pirlot's putative male X. fasciata from Indonesia is allocated to a new species, X. pirloti nom. nov. and K. H. Barnard's ‘X. fasciata’ from the Great Barrier Reef referred to Grandidierella gilesi Chilton. Another Xenocheira species from Western Australia is identified tentatively as X.? seurati Chevreux. Two new species of Ericthonius Milne Edwards are described, one from Tasmania (E. tacitus sp. nov.) and one from Western Australia (E. coxacanthus sp. nov.). The first record of E. pugnax Dana from mainland Australia is claimed for material from Western Australia. The taxonomic relationships of these species are evaluated and discussed. |
