Cuthona willani

Cervera, Garcia-Gomez & Lopez-Gonzalez, 1992


João Pedro Silva As some of you are aware, me and Gonçalo Calado are just finishing a field guide on portuguese sea slugs with a particular focus on Algarve. We're including 114 species but there are 4 for which we still don't have photos: Cuthona genovae Cuthona thompsoni Cuthona willani Onchidoris depressa If you have some photos of these species (it can be from another place unless there are some very clear variations along the distribution range) and would like to contribute to this field guide (copyright retained by you, of course, with authorship clearly mentioned and a signed copy delivered to you), please send me a message. Thanks!

Patrik Good Interesting. Can't help though. Good luck and hope to be able to dive in Portugal one day and put your guide to good use.

Eric Fly Hello, I will be in Portugal next year in late Spring and was wondering if you could reccomend the best place to dive and dive shop to hunt for Nudis. I will only dive one day as we will be pressed for time, but would really like to see a few new species. Any advice you have would be greatly appreciated.

João Pedro Silva Hi Eric Fly! It depends on where you'll be staying. If you go to the Algarve, check Subnauta (www.subnauta.pt) in Portimão. The diversity is bigger there. If you're staying in the Lisbon area, check Sesimbra (lots of dive centers there) and plenty of nudis that time of the year. Further north, near Peniche/Baleal, the dives in Berlengas have also lots of nudibranchs.

Gary Cobb Is it possible to say why you are using Cuthona??

Gary Cobb I am building an iPhone App for the Eastern Atlantic -Nudibranch ID and the species list contains 852 species. The area covered is from the Norway down to Cape Town. Good luck Joao!

João Pedro Silva Because of this, Gary: http://www.seaslugforum.net/showall/cuthonadisc

João Pedro Silva Also, the latest Iberian checklist also uses Cuthona: http://www.inoxnet.com/portisub/files/CatalogoIbericoOpistobranquios2006.pdf

João Pedro Silva I've yet to find the reference for the general use of Trinchesia instead of Cuthona (except for Cuthona nana).

Gary Cobb Trinchesia instead of Cuthona We feel that Michael Miller’s paper, in the Journal of Natural History 2004 Vol. 38 Issue 9, being the most recent work in this area coupled with his knowledge and experience with this group gives the decision to change most Cuthona to Trinchesia all the authority for acceptance that is needed. We don’t wish to refute every point made in the discussion listed above but suffice to say it is fair to accept the work until somebody puts in the time and effort to come forward with the information and the argument to dispute it. We think it should be accepted until fairly tested. We agree that science makes little incremental steps in progress and often that is just “nibbling away” at the matter. The whole nomenclature process is a fluid thing. Sure, it may change again later; it might flip flop several times but based on our current knowledge it makes sense to group species upon the currently researched and understood features. We fail to see the confusion. Some workers are by their nature “clumpers” grouping species together and others are “splitters” breaking them up into many different taxons. We don’t think Miller is guilty of being a “splitter”.

João Pedro Silva Still, I'd like to know if that particular study used material from the above species (and others of the same genus from the Atlantic). At least the abstract only mentions NZ species. WoRMS doesn't include the species I mentioned in the Trinchesia genus (http://www.marinespecies.org/aphia.php?p=taxdetails&id=391297) but in the Cuthona genus (http://www.marinespecies.org/aphia.php?p=taxdetails&id=138543).

Gary Cobb See new thread.

João Pedro Silva Orietta Rivolta, you have some nice shots of Onchidoris depressa on Nudipixel. Please let me know if you'd like to help us. http://www.nudipixel.net/photo/00033394/

Orietta Rivolta Ok João you can use my photos :-)))))

Gary Cobb Hey Joao! As you know I am building an iPhone App for the Eastern Atlantic and Mediterranean Sea called Nudibranch ID with so far 850 species. I came across a photo of Calma gobioophaga and would like to ask you if I may have permission to use your photos in this new App. I say photos meaning if I come across any other of your photos may I have permission. Your photos will have your name on each one and listed in the Contributing Photographers thank you view. If you have an iPhone I will send you a promo code for a free App. Thank you.
