Updating changes in the Iberian decapod crustacean fauna (excluding crabs) after 50 years

Abstract

An annotated checklist of the marine decapod crustaceans (excluding crabs) of the Iberian Peninsula has been compiled 50 years after the publication of “Crustáceos decápodos ibéricos” by Zariquiey Álvarez (1968). A total of 293 species belonging to 136 genera and 48 families has been recorded. This information increases by 116 species the total number reported by Zariquiey Álvarez in his posthumous work. The families with the greatest species richness are the Paguridae (28) and Palaemonidae (18). References by geographic sectors and for all species are given. The results show that 264 species are reported in the Atlantic sectors, while 178 have been found in the Mediterranean. The species richness and the differences between and within sectors are discussed; these are mainly due to the dimension of the areas, the depth ranges and the confluence of distinct water masses with a different origin and different physicochemical features. Consequently, the greatest richness of decapod species (excluding crabs) is found in the Gulf of Cádiz, with 194 species. The total number of decapods found in and around Iberian waters, including crabs, freshwater species and some new records not yet published, reaches 448.

Avilés Canyon System: Increasing the benthic biodiversity knowledge

“…In general, the crustaceans herein reported are new occurrences of widespread NE Atlantic species mainly extending the depth range; e.g. the mysid Chunomysis diadema (Tattersall and Tattersall, 1951;Nouvel and Lagardère, 1976;Elizalde et al, 1991), but also providing new boundaries for the distribution of peracarid species recently described in the southern Bay of Biscay (Kavanagh and Sorbe, 2006;Guerra-García et al, 2008;Frutos and Sorbe, 2010), or decapods not previously cited there (Macpherson, 1988;D'Udeckem d'Acoz, 1999, Baba et al, 2008Marco-Herrero et al, 2015;García Raso et al, 2018).…”

New species of deep-sea squat lobsters (Decapoda: Anomura: Galatheoidea) from Guadeloupe, French West Indies, unveiled through integrative taxonomy

“…belongs to the group of species having the maximum corneal diameter one-fourth the distance between bases of the anterolateral spines, second abdominal segment with spines, lateral parts of the posterior thoracic sternites without granules, a spiniform rostrum, article 1 of the antennular segment markedly elongated with the distomesial spine clearly shorter than the distolateral spine, distomesial spine of the antennal article 2 not exceeding the end of the fourth article, and dactylus with corneous spines on the entire flexor margin. Morphologically, the closest relative is M. microphthalma A. Milne-Edwards, 1880 from the Caribbean Sea (type locality), Brazil, south of Iceland, Bay of Biscay, NW Iberian Peninsula, Middle Atlantic Bight, Canary and Cape Verde islands at 677-2,094 m (de Melo-Filho & de Melo, 1992;García-Raso et al, 2018). The occurrences of this species in the Pacific Ocean are dubious (Baba et al, 2008).…”

Distribution and Ecology of Decapod Crustaceans in Mediterranean Marine Caves: A Review

“…Mediterranean cave decapod species have been assigned to six chorological categories, based on the review of d'Udekem d'Acoz [50] integrated with subsequent studies [27,[51][52][53][54], to compute the chorological spectra of the Mediterranean as a whole and of the ten geographical sectors outlined above (Figure 4 The endemics include six cave decapod species. Three are long known to live exclusively in the Mediterranean Sea (see Table S21 by C. Froglia in [55]): Hippolyte holthuisi, which has recently been recognized as the Mediterranean vicariant of the Atlantic congeneric H. varians Leach, 1814 [56], Maja squinado and Periclimenes amethysteus.…”
