Members of the genus Thorunna have always been a little tricky to me. Webmaster Mike had originally ID'ed this specimen as Thorunna sp. 5 in NSSI 2d Ed. But Thorunna sp. 6 is certainly close. The four white stripes, purple marginal spots and white mantle glands are almost indistinguishable between the two undescribed species. The only differences I can see, as pointed out in NSSI 2nd Ed, is that Thorunna sp. 5 has red-orange band on the anterior margin, and a white band on the posterior side of the rhinophores, missing in Mike's specimen. Until now, Thorunna sp. 5 is only known from the Marshall Islands and T. sp 6 from the Philippines. I think this is one of those where we need more info about the internal anatomy and some genetic analysis.

This region supports the most diverse marine fauna of any place in the world for most groups of marine organisms. The nudibranchs and sea slugs are no exception to this rule; there are about 3,000 described species of these organisms in the world and at least 40% of these have been found exclusively in the Indo-Pacific tropics. This book illustrates 2,138 Indo-Pacific nudibranchs and sea slugs, including many undescribed species.
