New occurrences and a new genus and species of 'Toothless' Odontasteridae (Asteroidea) from Australian waters (1986-2017)

Multiple new odontasterids were identified from deep-sea settings in Australian waters, including a new genus and species, Marshastra loisetteae gen. nov. sp. nov., from the shelf off Western Australia, and Hoplaster oloughlini sp. nov. from Tasmania and the south Pacific region. A phylogeny of Hoplaster suggests diversification from a Southern Hemisphere setting into the Atlantic and northward as well as across Tasmanian seamounts, indicating diversification into deep-sea habitats from shallower waters. The data has been acquired on the following RV Investigator voyage(s) IN2017_V03 with links to additional metadata, datasets, events, deployments, publications etc. If this data has been used in any products, please acknowledge with the following: We acknowledge the use of the CSIRO Marine National Facility (https://ror.org/01mae9353) in undertaking this research.
