Phidiana anulifera from Hong Kong

Hi Bill,
I have photos of something I labelled as Phidiana anulifera (Baba, 1949) from Hong Kong. I see that this is considered by some people to be synonymous with Facelinella semidecora (Pease, 1860) - illustrated in Bertsch and Johnson's Hawaiian Nudibranchs, 1981. Do you have an opinion on this one?

Dear Bernard,
I'm afraid I don't know enough about the Hawaiian Facelinella semidecora to be sure. From the published descriptions it seems to lack the red-orange lines of Phidiana anulifera and the rows of white specks on the cerata. My feeling is that they should be considered distinct until we know more about the colour variation in both species.
Cheers,
Bill Rudman
