Hypselodoris regina

Erwin Koehler here is a headache species from the Red Sea, it looks like Chromodoris colemani Rudman, 1982 or like Hypselodoris regina Marcus & Marcus, 1970 Help!

Gary Cobb According to Yanow I think this can only be Chromodoris strigata

Gary Cobb This species has been known to have brownish streaks on the mantle. Of course DNA will separate them quite nicely!

Erwin Koehler thanks, I will go with C. strigata for now...

Brian Sellick Can anyone help with this one. Sodwana Bay - South Africa, East Coast 35mm

Bruce Potter I don't know what it is, but it is spectacular

Gary Cobb This beauty looks just like Hypselodoris regina Marcus & Marcus, 1970

Brian Sellick Does anyone know what this one is? I'm going mad trying to figure it out.

Dewald Swanepoel Like Gary says above, it's a Hypselodoris regina

Brian Sellick Ok

Brian Sellick Sorry but I have to disagree, I'm gone through the SSF and all of those pictures are of slugs with stripes, this one doesn't have stripes.

Bruce Potter On page 165 of "Undersea Jewels" by Cobb and Willan there is a similar looking one identified as Hypselodoris sp.1

David A Mullins Go to the Sea Slug Forum Message 12225. Here you will see how the pattern can change across individuals. Look at the side of the body under the mantle in the top pic. You will see the same pattern there as on the tail and body of the specimen in your photo. Colours and patterns are not absolutely fixed in a species. Lines can become dashes, lines can cross over and form reticulations. Lines can disappear. This species is not well known so we are not aware of the full range of its presentation. I think Gary has made a good call here. The Hypselodoris sp. 1 in "Undersea Jewels" has since been named Hypselodoris jacksoni Wilson & Willan 2007. It is not that species.

Brian Sellick Ok cool. Thank you to everyone for their input. I really do appreciate it.
