Dear Alexander,
If it has caryophyllidia it is not a chromodorid. The most likely genera are Jorunna and Rostanga. Two species have been described from the west Atlantic. Jorunna spazzola (Marcus, 1955) from Brazil is translucent whitish with darker spots and Rostanga byga Marcus, 1968, also from Brazil, is red, like most species of the genus. It is possible that your animal is a species of Rostanga, and the tight circle of gills supports that idea, but the onmly way to be sure is to look at its anatomy.
Best wishes,
Bill Rudman
