The specimen #5 was misidentified by David W. Behrens as Thordisa oliva Chan & Gosliner, 2007. That is the reason why this species which was posted on 17 September 2010 at these websites a Discodorididae sp. A Family: Bergh, 1891 had been changed on 8 September 2011 into Thordisa oliva Chan & Gosliner, 2007. Thordisa cf. oliva differs in several points from Thordisa oliva: all tubercles are of the same colour as the mantle, not tan, the papillae are clear/ translucent, not tan. In most specimens are the rhinophores and gills tan, not opaque white, only specimen #5 has opaque white rhinophores and gills. IPN writes on Thordisa oliva at page 171: "Known from tropical South Africa and the Kerama Islands of southern Japan." The type locality of Thordisa oliva Chan & Gosliner, 2007 is Sodwana Bay, South Africa, I doubt the records from Japan. I changed it on 15 November 2019 into Thordisa cf. oliva Chan & Gosliner, 2007.
