Elysia cf. timida from the Florida Keys

Hello Dr. Rudman,
I just wanted to give you an update on one of the specimens I had previously posted to the Forum. I've finally gotten around to analyzing the DNA from the tiny specimen of Elysia cf. timida found in the Florida Keys [messages :#3410, #3419, #3428, #3515]. Based on the partial sequence of one gene (cytochrome oxidase subunit I) it appears to be Elysia timida. The sequence is divergent from the Mediterranean specimen referenced in GenBank but this difference appears to be a population level divergence and not at the species level. I say this because I have found much greater sequence divergence between other species of Elysia and other members of the Family.

It would be helpful to have specimens of Elysia timida from other parts of the Atlantic to confirm that this is a population level divergence. I've not been able to access any specimens from the Mediterranean, Cuba, Bahamas or Cape Verde. Any help with this specimens/populations (and others!) would be greatly appreciated.

Best Regards and it has been fabulous seeing all the sacoglossans on the forum!!

Thanks Anna,
It's nice to have some feedback on this animal. It seems to be one of a growing number of species which are proving to be amphiatlantic.
