Dear Bill,
My friend Moguricyo sent me these photos. I am sure that this animal belongs to
Siphopteron, but I have no idea what species. It might be Siphopteron quadrispinosum?

Masayoshi, N., 2002 (May 27) Is this Siphopteron quadrispinosum?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/7025Dear Nishina,
It certainly has similarities in colour to Siphopteron quadrispinosum but at present I wouldn't like to say just how much colour variation we should expect to occur in some of these yellow species of Siphopteron and Gastropteron. In this case, I think the colour pattern is so different from existing species that it is probably something unnamed. It is possible that the red lines could darken to brown or even black, but even then I don't know of a species with such markings. I think to be safe I will call it Siphopteron sp. 3.
Best wishes,
Bill Rudman
