The photos alongside were both identified by Yonow (1988) as typical of the species. Ventrally it has a black median longitudinal line on the sole of the foot.
This species was synonymised by Brunckhorst (1993) with Phyllidia elegans but see Bernard Picton's message suggesting that P. multifaria is a valid species and that Phyllidia schupporum Fahrner & Schrödl, 2000 is an unnecessary synonym.

During my researches on Coral Reef in Persian Gulf I found this species on coral Reef bed in Larak & Qeshm Island, and I need to your guidance about identification and biology information of this species?

This is a phyllidiid dorid. Unfortunately there are still some issues with the identification of phyllidiids, the most difficult being our inabiity to determine just how many species there are. Your specimen looks very like Phyllidia multifaria, a species which at present is known only from the northern Red Sea. There is another 'species' known only from the Red Sea, P. schupporum, which also looks very similar, but as is discussed on the Forum, it is most probably the same as P. multifaria.
Another possibility is Fryeria rueppelii, but in that species there is usually a yellow border around the mantle edge, and the anus opens below the mantle skirt.
My best guess is that this is P. multifaria, which would suggest it has a wider distribution than just the Red Sea.

I did take this photo last June when I was on a diving holiday in Egypt. I did saw there a lot of nudibranchs like always and most of them I did determine my self already. But by this one I need some help.
The picture is not really good, but I still hope you can see what you need to see for determine this nudibranch. Underwater I take a quick shot from this nudibranche because I thought that it was a Fryeria rueppelii. And I saw that several times before and have also some nice pictures of them. Later at home when I was looking to the pictures I saw that there was no yellow at the end of the mantle. And I mean that is one of the chararistics of Fryeria rueppelii. But if it is not a Fryeria rueppelii what is then?

So if I do not know which species it is I always look at the Seaslug Forum to find it out. From the pictures I saw on the Seaslug Forum I would see that it is probably a Phyllidia elegans. But I'm not sure of that and therefore I need some more help. So please can you determine this species for me.

Phyllidia elegans might be the correct answer but I am afraid some of the phyllidiids still need a lot of work. There is also the possibility that this is Phyllidia multifaria, but if you look at earlier discussions on the Forum there is some doubt about that species as well. I am tentatively identfying it as P. multifaria but not with great conviction.

Inside a cave at Samadai reef (Red Sea) we found two specimens of what we believe is Fryeria rueppelii. Is this true? When I look at the Factsheet I see a clear yellow border around the mantle and these guys don't have that. Also the smaller of the two (lower picture) has only 3 yellow dots on its body, where the larger one is covered in it. Is the smaller one a juvenile?
Also they were both sitting on the bottom on rocks covered in what we believe are pink sponges (or ascidians?). Can you help me identifying these slugs?

Thank you in advance!

I am pretty sure this is Phyllidia multifaria, but if you have a look at the Fact Sheet you will see there is still some debate about whether it is a 'good' species or not. Sometimes, when there are not a lot of anatomical or colour differences to separate species, it take some years before new names are accepted or rejected. That is why photos like yours can be helpful in building up a file of information on some of these 'rarer' species - which may turn out to be common species from rarely reported places.

I found this specimen during my recent diving cruise to Brothers Islands. Could you confirm it is Phyllidia multifaria, please? Unfortunately, I wasn’t able to take photos of its ventral view because of the surge. But I remember, the foot was pale.

I'm afraid I can't confirm that it is P. multifaria. It certainly has the right colour markings dorsally but that species is supposed to have a black median line on the sole of the foot, and you say you remember the foot to be pale. I guess from that you have no recollection of a black line. At this stage I will tentatively identify it as P. multifaria but I am open to suggestions

Following my earlier comments on Fahrner & Schrodl's paper redescribing Phyllidiopsis sinaiensis I would like to make some comments on their Phyllidia schupporum. It is clearly the same as Yonow's P. multifaria which Brunckhorst synonymised with P. elegans. I've attached some scans of Red Sea P. multifaria and Malaysian/Indonesian P. elegans. I think Brunckhorst was wrong to synonymise these species and Fahrner and Schrodl have now confused the situation further by redescribing P. multifaria as P. schupporum.
Consistent differences between P. multifaria and P. elegans seem to include much taller, compound mid-dorsal tubercles in P. elegans; the smaller tubercles in P. elegans are bright white - contrasting with ground colour of mantle, whilst in P. multifaria they are coloured almost the same as the mantle.

Yonow's P. multifaria certainly looks like Fahrner & Schrödl's Phyllidia schupporum. One thing I notice in Fahrner & Schrödl's description is that they specifically state that there are no characteristic markings on the sole of the foot. Yonow describes a median black line on the sole of P. multifaria and this character also appears in P. elegans. P. schupporum was described from a single preserved animal, the colour information apparently based on photographs. It is possible therefore that if there was a black median line on the foot, it could have dissolved in the preservative. Describing new species, especially in such a problematic group as the phyllidiids, from a single specimen, is not a good idea.
I guess the big problem is still to decide whether Brunckhorst was right in considering P. multifaria to be a synonym of P. elegans.
