Re: Dorid from Peru

In reference to Jorge's dorid from Peru, I was pretty sure Michael Schroedl had published recently on South American species of Anisodoris but couldn't find the references at home last night. They are:

• Schroedl, M. (1997) On the morphology of the magellanic nudibranch Anisodoris fontaini (d'Orbigny, 1837) and its synonymy with A. tessellata Bergh, 1898. The Veliger, 40(3): 228-233.
• Schroedl, M. (2000) Taxonomic revision of the common South American nudibranch Anisodoris fontaini (d'Orbigny, 1837), with discussion of its systematic placement. Journal of Molluscan Studies, 66: 69-81.

From these papers I am pretty sure this animal is Anisodoris fontaini which Schrodl says has a distribution on the both the Atlantic and Pacific coasts of South America from northern Argentina to the Chile-Peru border. If this is correctly identified, then it also extends further north into Peru. Schrodl considers that a number of species of Anisodoris and Neodoris that have been described from Sth America are synonyms of Anisodoris fontaini. Distinguishing external features, include the large orange-yellow tubercles, usually separated by a darker background colour on the mantle, and triangular grooved oral tentacles.
Best wishes,
