New species of Bathyacmaea from the Lau Basin

This is a new species of Bathyacmaea (Mollusca, Gastropoda, Patellogastropoda, Acmaeidae) that currently under description by Takenori Sasaki at the University of Tokyo Museum in Japan. I have found hundreds of these individuals in my quantitative collections of chemoautotrophic communities at the Lau Basin hydrothermal vent fields. They reminded me of the Patella limpet I learned about in my undergrad inverts class.
