Trapania maculata

Haefelfinger, 1960


Paula Lightfoot According to Habitas, Trapania maculata has been recorded in Dorset and the Lleyn Peninsula http://www.habitas.org.uk/marinelife/species.asp?item=W13130 but the NBN Gateway only shows the Dorset records. Does anyone know who's got the Welsh record(s)? Is it a Seasearch record that's just too recent to be on the Gateway yet i.e. one of this year's?

David Kipling I doubt it - much more likely a historic record. Bernard?

Paula Lightfoot ah good point - it is included on the MarLIN map, which is "based on published species records from 1950 to the present day". It's just that the Dorset records are all from 2010-12 so I wondered if it was one of those new arrivals from the south.

Liz Morris I think that I may have had records of Trapania in North Wales, verified by Bernard, but that they have not yet made it onto MR. I will have to check for you.

Liz Morris I will also check whether T.pallida actually.

Terry Griffiths Hi Paula had up to 5 on dive this year.

Paula Lightfoot Where Terry?

Terry Griffiths Hi Paula around the Torquay area i have photographs of them from 2007 , this year was a very good year for them .

Bernard Picton Paula, the record was from a long time back, maybe 30 years! I'll try and find the details.

Paula Lightfoot oops sorry! But it's been interesting to hear about recent records from other areas that haven't made it onto national distribution maps yet :)

Kate Lock There was also David Kipling record in the Skomer MNR which went onto MR as part of the Skomer nudibranch survey 201o report!!

Paula Lightfoot So is that an NRW rather than a Seasearch dataset Kate?

David Kipling Kate means T pallida.

Paula Lightfoot oh yes I can see that record.

Kate Lock wooops

Richard Yorke More Trapanina macculata from the Dorset coast.

Charlotte Bolton Great pics as ever Richard - where/when were these?

Richard Yorke Stennis Ledges on the Dysidea (10/7/10), and North Whitehouse Grounds (8/9/12)

Charlotte Bolton Thanks for the super-quick response! The 2012 sighting isn't in Marine Recorder but I am about to rectify that...

Lucas CerCur The correct spelling is Trapania maculata.

Richard Yorke Sorry, just copied and pasted it from the earlier post, just checked my keywords and it is correct there :-)

Kirstie Harris I wonder how many (if any) of these I've ignored, thinking they're Polycera quadrilineata......I must take the time to look at them properly in future!

Sarah Bowen Yes, definitely - we did the same with a Polycera-like specimen a few years back but something just didn't look right. Then we got Bernard to have a look at it and it turned out to be Trapania tartanella!

Carlos Fernández-Cid Ramos Trapania maculata. Galicia, Spain http://www.flickr.com/photos/78557484@N02/8461171164/in/set-72157632261258262

Egidio Trainito Why not Trapania hispalensis? It looks like an intermediate form.

Carlos Fernández-Cid Ramos I think is T.maculata. The other found here is

João Pedro Silva T. hispalensis, as T. tartanella, hasn't pigmented areas ahead of the gills and rhinophores. I support T. maculata.

João Pedro Silva This is a more typical T. tartanella, with the pigmented areas more orange near the tips: http://www.flickr.com/photos/jpsilva1971/6109278087/ Apparently this should be the only external different between T. tartanella and T. hispalensis.

João Pedro Silva On the differences between T. tartanella and T. hispalensis: http://www.seaslugforum.net/find/20698

Egidio Trainito Mediterranean T.maculata are usually more pigmented

João Pedro Silva Yes, I know, but not in the Atlantic. Nevertheless, it has only been seen once here in Portugal: http://www.flickr.com/photos/jpsilva1971/5701113310/

Carlos Fernández-Cid Ramos Trapania tartanella is the most frecuent here. I have seen once a T. palida (with very bad photos), and a T. maculata for the first time yesterday.

Lucas CerCur Dear colleagues to be sure of a right identification of both species, you need to check the radula. It is true that details on the orange/yellow pigmentation can infer what species is, but the radula is definitive. I will upload the original description of T. hispalensis.

Lucas CerCur I have just uploaded.
