ORCID iD: https://orcid.org/0000-0003-4849-4532 Summary: 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 spe- cies 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 differ- ences 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. Keywords: checklist; Decapoda Crustacea; Iberian Peninsula; species richness. Actualización de los cambios en la fauna de crustáceos decápodos ibéricos (excluidos los cangrejos) después de 50 años Resumen: Se ha realizado un listado comentado de los crustáceos decápodos marinos (excluidos los cangrejos) de la penín- sula ibérica, después de 50 años de la publicación “Crustáceos decápodos ibéricos” por Zariquiey Álvarez (1968). En total se mencionan 293 especies de 136 géneros y 48 familias. Estos datos incrementan en 116 el número de especies citadas por Zariquiey Álvarez en su obra póstuma. Las familias con mayor riqueza específica son Paguridae (28) y Palaemonidae (18). Se citan referencias para cada sector geográfico y especie. Las aguas atlánticas (en su conjunto) muestran una mayor riqueza, con 264 especies, mientras que 178 han sido citadas en aguas mediterráneas ibéricas. Se da el número de especies por sectores y se comentan las diferencias, consecuencia, principalmente, de la dimensión y rango de profundidad de cada uno de ellos y de la confluencia de masas de aguas con orígenes y caracteríticas fisico-químicas diferentes. Así, la mayor riqueza específica (sin incluir los cangrejos) se encuentra en el Golfo de Cádiz con 194 especies. El número total de especies de crustáceos decápodos en aguas ibéricas, incluyendo cangrejos, especies de agua dulce y algunas nuevas citas de especies aún no publicadas, sería de 448. Palabras clave: lista inventario; Crustacea Decapoda; península ibérica; riqueza de especies. Citation/Como citar este artículo: García Raso J.E., Cuesta J.A., Abelló P., Macpherson E. 2018.

INTRODUCTION The study of decapod crustaceans in the Iberian Peninsula began in the last part of the 19th century, with information and lists obtained from different coastal areas (e.g. Brito Capello 1873, Barceló-Combis 1875, Bolívar 1892, 1916, Buen 1887, 1916, Ferrer Galdiano 1920, 1940, Miranda y Rivera 1921), as well as from the results from the research expeditions that covered parts of these waters (see García Raso 1996 and refer- ences cited therein). The first checklist for all Spanish waters was compiled by Miranda y Rivera (1933) and subsequently extended by Zariquiey-Cenarro (1935a, b, 1942). Zariquiey Álvarez (1946) published a syn- thesis, “Crustáceos Decápodos Mediterráneos”. In Portugal, Nobre (1931, 1936) published “Crustáceos Decápodos e Stomatópodes marinhos de Portugal”. These relatively intensive works on the Iberian deca- Fig. 1. – Map of the Iberian Peninsula and nearby waters show- pods culminated just 50 years ago with the publication ing the areas considered to characterize the spatial distribution of of “Crustáceos Decápodos Ibéricos”, a posthumous decapod crustacean species.
