Limenandra nodosa from Colombia

From: Elianny Domínguez Tejo.

Dear Bill,
Concerning the 'funny nudibranch' you thought might be Limenandra nodosa. Here is another species which we think looks like Limenandra nodosa. We found it on Dictyota sp at 3 m of depth, on the Caribbean Coast of Colombia. It is 6 mm long.

It has 12 circles, 6 of them are complete white and the other 6 are orange whith a white center. The rhinophores have little white buds or papilles? at the end; but the tentacles are complete smooth.

We don't think the 'funny nudibranch' is Limenandra nodosa and have sent separately photos of what we think is Limenandra. It didn't have any kind of circles. The cerates are arranged just like in Austraeolis ornata and Austraeolis catina. The cerata form little crowns (in the dorsal region) with longer cerates towards the head of the animal. The crowns are smaller and with shorter cerates towards the posterior end of the body. The color pattern is also similar to the one on Austraeolis ornata, only lighter. I have more pictures but the one I sent you was the clearer one.

Dear Elianny,
From your description I agree that it fits Limenandra nodosa quite well. Did you notice whether this species waved its cerata rhythmically in a jerky backwards and forwards movement?
Best wishes,
Bill Rudman
