Diversity of Norwegian Sea Slugs (Nudibranchia): New Species to Norwegian Coastal Waters and New Data on Distribution of Rare Species
Fauna norvegica 2013 Vol. 32: 45-52. ISSN: 1502-4873 Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species Jussi Evertsen1 and Torkild Bakken1 Evertsen J, Bakken T. 2013. Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species. Fauna norvegica 32: 45-52. A total of 5 nudibranch species are reported from the Norwegian coast for the first time (Doridoxa ingolfiana, Goniodoris castanea, Onchidoris sparsa, Eubranchus rupium and Proctonotus mucro- niferus). In addition 10 species that can be considered rare in Norwegian waters are presented with new information (Lophodoris danielsseni, Onchidoris depressa, Palio nothus, Tritonia griegi, Tritonia lineata, Hero formosa, Janolus cristatus, Cumanotus beaumonti, Berghia norvegica and Calma glau- coides), in some cases with considerable changes to their distribution. These new results present an update to our previous extensive investigation of the nudibranch fauna of the Norwegian coast from 2005, which now totals 87 species. An increase in several new species to the Norwegian fauna and new records of rare species, some with considerable updates, in relatively few years results mainly from sampling effort and contributions by specialists on samples from poorly sampled areas. doi: 10.5324/fn.v31i0.1576.

<I>Tritonia</I> (Opisthobranchia: Gastropoda)
BULLETIN OF MARINE SCIENCE, 40(3): 428-436, 1987 A NEW SPECIES OF TRITONIA (OPISTHOBRANCHIA: GASTROPODA) FROM THE CARIBBEAN SEA Terrence M. Gosliner and Michael T.

Seven species in three or four genera are known from tropical and subtropical waters of the region. Investigations by one of us (M.T.G.) in the Bahamas yielded specimens of what appeared to be an undescribed species of Tritonia. Subsequently, our joint investigations in Quintana Roo, Mexico have provided additional specimens of this species.

Knowledge of the host preferences of the Mediterranean populations is still scarce. Few records of this nudi- branch have been reported from the eastern Mediterranean basin. With this report, the occurrence of T. nilsodhneri within the Mediterranean basin is extended to the Adriatic Sea. Furthermore, the list of the host species associated to the Mediterranean populations for feeding habits is increased from two up to five. Mediterranean specimens of T. nilsodhneri were observed for the first time feeding and spawning on Leptogorgia sarmentosa, Eunicella cavolini and E. labiata. Finally, these last two Gorgoniidae species are also reported here as a new host species for T. nilsodhneri.

Goddard Abstract: The polyps of Discophyton rudyi (Verseveldt and van Ofwegen, 1992), a small, aggregating, alcyonacean soft coral found on rocky shores in the northeast Pacific Ocean, are selectively preyed on by the nudibranch Tritonia festiva (Stearns, 1873). In the laboratory, D. rudyi retracted their polyps when exposed to water-borne cues from a conspecific colony that was successfully attacked by T. festiva. This same inter-colony response was elicited by attacks simulated with fine scissors, but not by (i) the presence of T. festiva attempting to feed but prevented from damaging its prey, (ii) the simple withdrawal of the soft coral polyps, or (iii) seawater controls. The cue(s) eliciting polyp retrac- tion therefore emanate from the soft coral and not its nudibranch predator. Tritonia festiva often attacks neighboring colonies, which are usually separated by only a few millimetres, in rapid succession but will not attack colonies with retracted polyps. It also cannot move rapidly to reach more distant colonies. Therefore, polyp retraction by one colony in response to predation on a neighboring colony effectively serves as an anti-predatory alarm response. -

BROWN Department of Zoology, The University, Bristol & PETER J. HUNNAM Dale Fort Field Centre, Dale, Have1/ordwest, Dyfed INTRODUCTION The opisthobranchs of sea areas to the south-west of England have received relatively close scrutiny in recent years. Advances in understanding the system atics and ecology of these animals have been possible as a result of numerous specimens collected by SCUBA divers. This has led to two publications which will be of assistance in the study of specimens from Lundy. Hunnam & Brown (1975) list and describe species from the Dale peninsula which is thought to be hydrographically 'downstream' from Lundy, while Thompson & Brown (1976) describe all valid species known from the British Isles with information on ecology and distribution. Future collections will undoubtedly supplement the Lundy List but it was felt necessary to publish at the present time as several new records for the Bristol Channel and one new record for Great Britain are included. -

Os caracteres sistemáticos são discutidos e foram feitas lista e chave para os gêne ros das Tritoniidae. A distribuição de Marionia cucullata é estendida para o norte até o Estreito da Flórida. As novas espécies, Tritonia eriosi da Ilha dos Lobos, Uruguai, e Marionia tedi do Estreito da Florida são descritas e desenhadas. Tritonia odhneri Tardy, 1963, da Bretanha é pré-ocupada por Tritonia odhne- ri Marcus, 1959, do Chile. Propondo chamar a espécie de Tardy de Tritonia nils- odhneri, nom. nov. A Marionia cucullata Vicente & Arnaud, 1979 da Terra Adelie, tem processos velares simples, e placas gástricas não são mencionadas. Portanto não per tence ao gênero Marionia. Tritonia episcopalis Bouchet, 1977, é provavelmente uma Tritoniella devido à forma da ponta do seu penis. ABSTRACT The seven western Atlantic Tritoniidae are described and figured. The syste matical characters are discussed, and a list and key of the genera of the Trito niidae are given. The range of Marionia cucullata is extended northward to Flo rida Strait. The new species Tritonia eriosi from Ilha dos Lobos, Uruguay, and Marionia tedi from Florida Strait are described and figured. Tritonia odhneri Tardy, 1963, from Brittany is preoccupied by Tritonia odh neri Marcus, 1959, from Chile. I propose to call Tardy’s species Tritonia nilsodh- neri, nom. nov. The Marionia cucullata Vicente & Arnaud, 1979 from Adelieland has simple velar processes, and stomachal plates are not mentioned.
