- From caves to seamounts: the hidden diversity of tetractinellid sponges from the Balearic Islands, with the description of eight new species. Díaz, Julio A Ordines, Francesc Massutí, Enric Cárdenas, Paco Animals Porifera Spain Caves Phylogeny Biodiversity Ecosystem DNA Barcoding, Taxonomic The sponge fauna of the Western Mediterranean stands as one of the most studied in the world. Yet sampling new habitats and a poorly studied region like the Balearic Islands highlights once again our limited knowledge of this group of animals. This work focused on demosponges of the order Tetractinellida collected in several research surveys (2016-2021) on a variety of ecosystems of the Balearic Islands, including shallow caves, seamounts and trawl fishing grounds, in a broad depth range (0-725 m). Tetractinellid material from the North Atlantic and more than twenty type specimens were also examined and, for some, re-described in this work. All species were barcoded with the traditional molecular markers COI (Folmer fragment) and 28S (C1-C2 or C1-D2 fragment). A total of 36 species were identified, mostly belonging to the family Geodiidae (15 species), thereby bringing the number of tetractinellids recorded in the Balearic Islands from 15 to 39. Eight species from this study are new: sp. nov., sp. nov., sp. nov., sp. nov., sp. nov. and sp. nov. from the Balearic Islands; sp. nov. and C sp. nov. from the North East Atlantic. and are reported for the first time since their description in Corsica in 1983. is documented for the first time in the Mediterranean Sea. Finally, after comparisons of type material, we propose new synonymies: as a junior synonym of as a junior synonym of and as a junior synonym of .
