Concerning message #22345:
Dear Bill and Katrina,
This morphotype was described as a new species Hypselodoris olgae by Ortea & Bacallado (2007) based on specimens collected at Mexico and Cuba.
It was previously misidentified with Hypselodoris marci at Ortea et al.(1996) paper.
I believe that all the animals you have called Hypselodoris sp. 5 on the Forum are H. olgae except for the specimen from Brian Mayes [message #9824] which probably belongs to another species. What species? I don´t know. It is only one of the many morphotypes that occur at the Caribbean Sea which need more investigation.
Ortea, J. & Bacallado, J.J. (2007 for 2006) Descripción de una nueva especie de Hypselodoris Stimpson, 1855 (Mollusca: Nudibranchia: Chromodorididae) nombrada en homenaje a Olga Ucelay Sabina. Revista de la Academia Canaria de Ciencias, 18(4): 53-60.

Thanks for letting me know about H. olgae and for sending me a copy of Ortea & Bacallado's paper which I had not as yet seen. Certainly there is more work needed on these Caribbean - West Atlantic species. I see the authors suspect this species is a direct developer from the size of the eggs. Direct development can lead to speciation or 'subspeciation' through genetic isolation but there are also many examples of direct developing species with wide geographic distributions. If there are a group of similarly coloured species, then Brian Mayes animal [#9824] could well be different as it lacks a dark blue rhinophore tip. In many ways it looks like the animal I have identified as H. marci [see #13280]. Apart from solving the biological puzzle of just how many species there are in this group, we also have the unfortunate nomenclatural puzzle of interpreting the original description of H. marci.
