re: another Elysia. This body morph is similar to some of the juvenile forms of a couple of species we have that feed on Caulerpa. At first we had them as separate species and then found some a bit smaller and others that were starting to stretch out a bit. We don't have one with red on the rhinophores nor the blue on the neck. The white mid dorsal spot probably marks the pericardium. If it has a long tube running aft of the pericardium it would even be more like our Caulerpa feeders. We were tempted to equate one of our species with E. subornata (=E. cauze) but Kathe Jensen said they differ internally so they have just remained Elysia sp.

And another Elysia sp from Kerama Is.

June 27, 1999
From: Atsushi Ono

Dear Bill,
Could you help me with another opisthobranch from Kerama Island, near Okinawa.

I think this is Elysia sp. too. 5m depth, 7mm length, in Jan.-May 1999. I observed 3 individuals.

They all have white spot on their back.
Their rhinophores color are green to red. Their size are 3 to 7mm.

Sincerely,
Atsushi Ono

Dear Atsushi,
Another elysiid! The whitish blue spot behind the rhinophores looks as though it could be an important distinguishing feature of the colour pattern. However I can't find a described species with that pattern. In shape it looks somewhat like Crosslandia but the head and rhinophores don't look right.
Best wishes,
Bill Rudman.
