This is an undescribed species of the genus Armina. I call it Armina
sp. B, to distinguish it from other undescribed Armina sp. This
Armina sp. B, can be distinguished from other arminaceans by the black
foot with a red border and the traverse black patch on the mantle.
More informations on Armina sp. B are at
Bill Rudman's Sea Slug Forum!
