Dear Rie,
Thanks for these photos. With Jun Imamoto's photos [#14076], it greatly helps clarify this species for me. Of particular interest is your lower right photo which shows an animal with a faint yellow spot on the head, which was considered to be a characteristic of Elysia flavomacula, and is the feature which gave the species its name.

From these photos I think we can be fairly sure that Elysia flavomacula is a synonym of Elysia atroviridis.

Best wishes,
Bill Rudman
