Dear Bill,
On the third instalment of the new aeolids from my paper I am sending you Cuthona behrensi. I found this species in Panama, between the Gulf of Panama and the Gulf of Chiriqui and have not found it again since.
Locality: Azuero Peninsula, 30 feet, Panama, tropical eastern Pacific, 01 May 2003, Under rocks. Length: 6 mm. Photographer: Ali Hermosillo.
The striking coloration made it easy to realize it was a new species, which we decided to name after our dear friend Dave Behrens.
I am sending you a picture and a drawing (to continue on with the art theme you got going with the beautiful Hypselodoris of the Caribbean (#20308 )) by Jan Kocian, who is a great artist and photographer. Visit his gallery and you will enjoy his art and humor. http://www.pnwscuba.com/critterwatchers/janscreations.htm

Dear Ali,
This is one animal you wouldn't need your flouro lighting for - I find this pattern of white and bright yellow particularly startling - even for a nudibranch.
Best wishes,
Bill Rudman
