Isopods (isopoda), Excluding Epicaridea, from the Oceanographic Expeditions "Fauna Iii/Iv" (mncn) in the Levantine Archipelagos of the Iberian Peninsula (western Mediterranean)

This study focused on the isopod fauna from the Levantine area of the Iberian Peninsula (western Mediterranean). The sampling campaigns were carried out on board the RN "Garcia del Cid". Seventy-nine samples containing isopods (Epicaridea excluded) were collected around various archipelagos (Balearic, Columbretes (Castellon de la Plana), Hormigas (Palos Cape, Murcia) and Alboran Island) in June-July 1994 (Fauna III: 42 samples) and July 1996 (Fauna IV: 37 samples), at depths between 0 and 650 m, although the majority of samples obtained by scuba diving were found between depths of 3 and 47 m. The bottoms sampled were diverse (photophyle and sciaphile algae, Posidonia, precoralligenous and coralligenous, detritus and maerl); vertical walls and caves were also sampled. A total of 356 individuals, included in 36 species belonging to 24 genera, 15 families and 6 suborders, were found, including the first record of three species (Boreosignum maltinii (Schiecke & Fresi, 1972), Gnathia inopinata Monod, 1925 and Idusa dieuzeidei Dollfus, 1950) from Iberian waters, five species (Microjaera anisopoda Bocquet & Levi, 1955, Rocinela danmoniensis Leach, 1818, Eurydice truncata (Norman, 1868), Natatolana neglecta (Hansen, 1890) and Stenosoma albertoi (Castellanos & Junoy, 2005)) from Mediterranean Iberian waters, and two species (Joeropsis legrandi Juchault, 1962 and Aega rosacea (Risso, 1816)) from the Balearic Islands. Four tables showing the sampling and ecological data, the material examined, the previous records from the areas of Iberian waters under study and the range of depth of species are provided.
