Generic placement of Limenandra nodosa

Dear Dr. Rudman,
This species genus has been changed from Limenandra to Baeolidia.

I find this species once in a while in Bahia de Banderas, usually hiding within algae. As you correctly mention, it moves (or better jerks along) pretty much like Aeolidiella alba, and that is basically what gives it away.

Thanks Ali,
I'm glad to hear you have found that it 'jerks' along. That means we now have observations of it doing this from both the Caribbean and the east Pacific, to match mine from Tanzania and the western Pacific. I have included a 'close-up' to show the papillae on rthe rhinophores and the cerata.

Concerning its generic placement. Terry Gosliner did indeed place it in Baeolidia but Michael C. Miller's recent review of the family considers the genus Limenandra should be retained, and so I will leave it there. As I have said in a recent message about Aeolidiopsis, this family of aeolids is still causing some problems in our understanding of how the species are related to one another

• Miller, M.C. (2001) Aeolid nudibranchs (Gastropoda: Opisthobranchia) of the family Aeolidiidae from New Zealand waters. Journal of Natural History, 35: 629-662.

Best wishes,
