This study was carried out, through a total of 271 scuba dives, from 2017 to the beginning of 2020 in four sites located along the Ionian coasts of Sicily: Catania, Aci Trezza, Santa Maria La Scala and Santa Tecla. Through a photographic data collection, 95 taxa, representing 17.27% of all Mediterranean marine Heterobranchia, were reported. The order with the highest number of found species was that of Nudibranchia. Among the study areas, Catania, Santa Maria La Scala and Santa Tecla had not a remarkable difference in the number of species, while Aci Trezza had the lowest number of species. Moreover, among the 95 taxa, four species considered rare and six non-indigenous species have been recorded. Since the presence of a high diversity of sea slugs in a relatively small area, the central-eastern coast of Sicily could be considered a zone of high biodiversity for the marine Heterobranchia fauna.

A Polyvalent and Universal Tool for Genomic Studies In
A polyvalent and universal tool for genomic studies in gastropod molluscs (Heterobranchia: Tectipleura) Juan Moles1 and Gonzalo Giribet1 1Harvard University Faculty of Arts and Sciences April 28, 2020 Abstract Molluscs are the second most diverse animal phylum and heterobranch gastropods present ~44,000 species. These comprise fascinating creatures with a huge morphological and ecological disparity. Such great diversity comes with even larger phyloge- netic uncertainty and many taxa have been largely neglected in molecular assessments. Genomic tools have provided resolution to deep cladogenic events but generating large numbers of transcriptomes/genomes is expensive and usually requires fresh material. Here we leverage a target enrichment approach to design and synthesize a probe set based on available genomes and transcriptomes across Heterobranchia. Our probe set contains 57,606 70mer baits and targets a total of 2,259 ultra-conserved elements (UCEs). Post-sequencing capture efficiency was tested against 31 marine heterobranchs from major groups, includ- ing Acochlidia, Acteonoidea, Aplysiida, Cephalaspidea, Pleurobranchida, Pteropoda, Runcinida, Sacoglossa, and Umbraculida. The combined Trinity and Velvet assemblies recovered up to 2,211 UCEs in Tectipleura and up to 1,978 in Nudipleura, the most distantly related taxon to our core study group. Total alignment length was 525,599 bp and contained 52% informative sites and 21% missing data. Maximum-likelihood and Bayesian inference approaches recovered the monophyly of all orders tested as well as the larger clades Nudipleura, Panpulmonata, and Euopisthobranchia. The successful enrichment of diversely preserved material and DNA concentrations demonstrate the polyvalent nature of UCEs, and the universality of the probe set designed. We believe this probe set will enable multiple, interesting lines of research, that will benefit from an inexpensive and largely informative tool that will, additionally, benefit from the access to museum collections to gather genomic data. -

A New Species and Genus of Aeolid Nudibranch (Mollusca, Gastropoda) from the Iberian Coasts
Bull. Mus. natn. Hist. nat.. Paris, 4e sér., 11, 1989, section A, n° 4 : 733-741. A new species and genus of aeolid nudibranch (Mollusca, Gastropoda) from the Iberian coasts by José Carlos GARCIA-GOMEZ and Juan Lucas CERVERA Abstract. — Two spécimens of a new species of aeolid nudibranch from Southern Portugal, Algarvia alba n. sp., are described. This species is placed in the new genus Algarvia, within the Facelinidae. Algarvia n. gen. differs from members of the closely allied gênera according to a set of morphological features, of which the more remarkable are the following : head with an enlargement on each side, rhinophores with some lamellae (they can be interrupted in front and/or behind the rhinophoral axis), nephroproct and gonopore interhepatic, masticatory border of jaws smooth, pénis simple and unarmed. We add a comparative table among the new genus and other closely allied gênera. Résumé. — Nous décrivons une espèce nouvelle de nudibranche éolidien du sud du Portugal, Algarvia alba n. sp., à partir de deux exemplaires. La nouvelle espèce est placée dans le nouveau genre Algarvia, inclus dans les Facelinidae. Algarvia n. gen. est distinct des autres genres de la famille par plusieurs caractéristiques morphologiques dont les plus remarquables sont : tête élargie de chaque côté, rhinophores ayant quelques lamelles (qui peuvent être interrompues devant et/ou derrière l'axe du rhinophore), néphroprocte et gonopores interhépatiques, bord masticatoire des mâchoires lisse, pénis simple et inerme. Un tableau comparatif du nouveau genre avec d'autres genres étroitement liés est donné. J. C. GARCIA-GOMEZ and J. L.

The Burnaia helicochorda (Miller 1987), originally ascribed to monospecific genus Burnaia could not be included in the Aeolidia Cuvier, 1798, was considered a member of Aeo- previous analysis, due to the lack of material. This study lidiidae although the author did not provide any reason for includes two specimens of Burnaia helicochorda from that systematic position. According to Miller (1987, 2001), Australia and places them in their systematic position using this species was of easy identification by its external two mitochondrial and one nuclear genes (COI and 16S, colouration, large body, lamellate rhinophores, and cerata and H3, respectively). A description of its anatomy is also in arches. Actually, because of all these morphological included with colour pictures of the animal and scanning aspects, Miller (2001) decided to create a new genus, electron micrographs of radula and jaws.

Many species have very short life- cycles, so they can respond rapidly to changes in environmental conditions. the new south wales coast is a recognised climate change hot-spot and southward shifts in distribution have already been documented for several species. however, thorough documentation of present distributions is an essential prerequisite for identifying further range extensions. while distribution data are available in the public realm, much is also held privately as photographic collections, diaries and logs. this paper consolidates the current occurrence data from both private and public sources as part of a broader study of sea slug distribution in south-eastern Australia and provides an inventory by region. A total of 382 species, 155 genera and 54 families is reported from the mainland coast of new south wales. -

It is also the second published record of this species along the Italian coasts and the first record from the Ligurian Sea. A single specimen was reported during a scuba dive, crawl- ing on small stones inside the Site of Community Importance ‘Fondali Noli – Bergeggi SCI’, at a depth of 3.5 m. The species, described in 1927 in South Africa, is considered to be rapidly expanding its original areal distribution thanks to maritime traffic.
