Formerly placed in the genus Miamira, Valdes & Gosliner (1999) have recently proposed that these animals are members of the chromodorid genus Ceratosoma. The number of species in the 'Miamira-group' is still not clear. Some authors, such as Baba & Hamatani (1974), consider there is a single species which ranges from the green 'sinuata' form to the purplish 'flavicostata form. Others consider there are sufficient distinctions in external shape and colour, and radular morphology, to distinguish two or three species. While the extremes are very clear, there are many intermediate forms which suggest perhaps a continuum. At present I have placed them all as a single species, but this is through lack of knowledge rather than through some great insight.
