Distribution This species has been previously recorded from the Australasian Seas, Indian Ocean, South Africa and Vema Seamount, from the littoral zone to a depth of 219 m (Millard 1966, 1975). Our records from Valdivia Bank, between 476 and 707 m, represent the deepest known localities for this species.
