Author's notes

Identified from description at https://www.gbri.org.au/Classes/2012/Diademasavignyi|TessaJones.aspx?PageContentID=2993 The author states that this species can be separated from others in that genus by the 5 continuous blue lines down the interambulacra and the blue-ringed anal cone. It is stated to be primarily a northern species, which extends down to the north coast of NSW. Its presence in Narooma would suggest an extension of its range.
