Berghia rissodominguezi Muniain & Ortea, 1999
Well after much discussion with my colleagues, I am guessing this is Berghia rissodominguezi.
Our collective decision is based primarily on the tubercles on the posterior side of the rhinophores, although the colors do not completely agree with those in the photo of this species on page 274 of Caribbean Sea Slugs . Carol had originally ID'ed this critter as Antaeolidiella indica, but that species has smooth rhinophores.
I would love to comment on the very unusual character, Dr. Carlos J. Risso-Dominguez, of Argentina, for whom the species was named, but I will refrain from this distasteful topic. But oh the stories I could tell.
This is a very interesting find of a fairly rare species, but then again not that many folks dive the northern Gulf of Mexico for nudibranchs. Thanks Carol.

I am retired from the Air Force. I started scuba diving in 1991 when stationed at Anderson AFB, Guam. I began doing underwater photography in 1992 when my husband abandoned his Sea & Sea Motormarine camera for underwater video. I live in Port St Joe, Florida, on the northern Gulf of Mexico. I help my husband Bob run the
Mexico Beach Artificial Reef Association, a non-profit organization that raises funds and builds reefs on the sandy bottom. One of my favorite duties as a volunteer is surveying the artificial reefs we deploy. My best dives are ones where I record something I have never seen before, like this Berghiarisso dominguezi. This photo was taken with a Canon G15 camera with a +5 magnifier. There were actually two nudibranchs, but one quickly crawled inside the empty helmet shell they were perched on.
