A new species of Austrofilius (Crustacea, Isopoda, Janiridae) from the Western Mediterranean

A new species of janiridean isopod, Austrofilius mediterraneus sp. nov., from the Columbretes Islands (Castellón de la Plana), Mediterranean coast of the Iberian Peninsula, is described, given it is the first record of the genus in the Northern Hemisphere. It is mainly distinguished from the other two species of the genus by the male pleopod 1, which is wider at the apex and with hooked lateral lobes, curved and nearly surpassing medial lobes. Furthermore, the female operculum shows only four distolateral setae. The rostrum of Austrofilius mediterraneus sp. nov. is extended into single frontolateral tips but is shorter than in A. furcatus Hodgson, 1910.

Epibiotic bryozoans on deep-water seleractinian corals from the Catalonia slope (western Mediterranean, Spain, France)

The bryozoan fauna growing on deep-water corals (Lophelia, Madrepora) from the upper-slope of Catalonia (Blanes and Banyuls-sur-mer: NW Mediterranean Sea) was studied. Among the 36 species recorded, a new species, Escharella acuta sp. nov., and a new subspecies, Escharina dutertrei protecta ssp. nov., are described; five other species have been rarely reported or were unknown from the Mediterranean Sea (Copidozoum exiguum, Amphiblestrum flemingii, Schizomavella neptuni, Smittina crystallina, Phylactellipora eximia) . This epibiotic bryozoan fauna differs clearly from shallow-water assemblages and comprises a greater proportion of boreo-atlantic species.
