Abstract

O’Loughlin, P.M. and Bribiesca-Contreras, G. 2015. New asterinid seastars from northwest Australia, with a revised key to Aquilonastra species (Echinodermata: Asteroidea). Memoirs of Museum Victoria 73: 27–40. The Woodside/Western Australian Museum Kimberley Project 2008–2015 collected four small asterinid seastar specimens from Cassini Island and Long Reef in the Kimberley region of north Western Australia. The specimens are lodged in the Western Australian Museum. They represent two new species of Aquilonastra O’Loughlin: Aquilonastra alisonae sp. nov.; Aquilonastra cassini sp. nov. An updated key is provided for species assigned to Aquilonastra, and a table distinguishing Aquilonastra species from the Kimberley region.
