Miamira flavicostata

Ryuta Ishikawa Ceratosoma Sinuata(van Hasselt, 1824) Osezaki, Japan

Lindz Warren Miamira flavicostata Baba, 1940

Ryuta Ishikawa This is "Ceratosoma magnificum (Eliot, 1910) " in a japanese picture book now. This nudibranch has many id.

Lindz Warren But C. magnificum, M. flavicostata are very different. We need to ask the experts :-)

Erwin Koehler some say they are the same species (synonyms) the SSF discussed it here: http://www.seaslugforum.net/find/19854

João Pedro Silva Have you checked if material from these species was used in the latest revision of the Chromodorididae?

Ryuta Ishikawa It's called "Ceratosoma magnificum (Eliot, 1910)" at the book of "Nudibranchs in Japan beta edition(Dec 2012)". This book is latest pictorial book in Japan.

João Pedro Silva But not the latest scientific publication. By April 2012 the latest revision of the family was published: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0033479 It's not simply a revision based on morphology but a molecular (DNA) study. Ceratosoma magnificum it's now obsolete and the currently accepted name is Miamira magnifica. Updated online sources already reflect this, you can check for yourself: http://www.marinespecies.org/aphia.php?p=taxdetails&id=560048

João Pedro Silva I know it takes a lot of effort to keep updated but it's a pity the "Nudibranchs in Japan" book didn't use the latest knowledge available. I co-authored a book on the "Sea Slugs of the Algarve" released in December 2012 and we changed all the Chromodorididae to reflect it (and the manuscript was delivered by the end of August). http://hypselodoris.blogspot.pt/p/guia-de-campo-field-guide.html
