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.

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”.

In males, endopod of second pair 5 of pleopods (abdominal appendages) with appendix masculina only. Third and fourth pleopods single-branched. Telson generally armed with a pair of fixed lateral spines. Colour: body colour varies from dark brown to reddish; often with distinct spots or colour markings on carapace and/or abdomen - such colour markings are specific and very useful in distinguishing the species. Habitat, biology, and fisheries: All members of this family are marine and can be found from shallow to deep waters (to depths of more than 400 m). They are all benthic and occur on both soft and hard bottoms. Their sizes are generally small, about 2 to 8 cm, but some species can reach a body length over 15 cm. The sexes are easily distinguished by the presence of a large copulatory organ (petasma) on the first pair of pleopods of males, while the females have the posterior thoracic sternites modified into a large sperm receptacle process (thelycum) which holds the spermatophores or sperm sacs (usually whitish or yellowish in colour) after mating.

  • Decapod Crustacean Assemblages Off the West Coast of Central Italy (Western Mediterranean)
    SCIENTIA MARINA 71(1) March 2007, 19-28, Barcelona (Spain) ISSN: 0214-8358 Decapod crustacean assemblages off the West coast of central Italy (western Mediterranean) EMANUELA FANELLI 1, FRANCESCO COLLOCA 2 and GIANDOMENICO ARDIZZONE 2 1 IAMC-CNR Marine Ecology Laboratory, Via G. da Verrazzano 17, 91014 Castellammare del Golfo (Trapani) Italy. E-mail: [email protected] 2 Department of Animal and Human Biology, University of Rome “la Sapienza”, V.le dell’Università 32, 00185 Rome, Italy. SUMMARY: Community structure and faunal composition of decapod crustaceans off the west coast of central Italy (west- ern Mediterranean) were investigated. Samples were collected during five trawl surveys carried out from June 1996 to June 2000 from 16 to 750 m depth. Multivariate analysis revealed the occurrence of five faunistic assemblages: 1) a strictly coastal community over sandy bottoms at depths <35 m; 2) a middle shelf community over sandy-muddy bottoms at depths between 50 and 100 m; 3) a slope edge community up to 200 m depth as a transition assemblage; 4) an upper slope community at depths between 200 and 450 m, and 5) a middle slope community at depths greater than 450 m. The existence of a shelf- slope edge transition is a characteristic of the western and central Mediterranean where a Leptometra phalangium facies is found in many areas at depths between 120 and 180 m. The brachyuran crab Liocarcinus depurator dominates the shallow muddy-sandy bottoms of the shelf, while Parapenaeus longirostris is the most abundant species from the shelf to the upper slope assemblage.

GONZÁLEZ University of Las Palmas de Gran Canaria, i-UNAT, Campus de Tafira, 35017 Las Palmas de Gran Canaria, Spain. E-mail: [email protected]. ORCID iD: 0000-0001-8584-6731. Abstract The complete list of Canarian marine decapods (last update by González & Quiles 2003, popular book) currently com- prises 374 species/subspecies, grouped in 198 genera and 82 families; whereas the Cape Verdean marine decapods (now fully listed for the first time) are represented by 343 species/subspecies with 201 genera and 80 families. Due to changing environmental conditions, in the last decades many subtropical/tropical taxa have reached the coasts of the Canary Islands. Comparing the carcinofaunal composition and their biogeographic components between the Canary and Cape Verde ar- chipelagos would aid in: validating the appropriateness in separating both archipelagos into different ecoregions (Spalding et al. 2007), and understanding faunal movements between areas of benthic habitat. The consistency of both ecoregions is here compared and validated by assembling their decapod crustacean checklists, analysing their taxa composition, gath- ering their bathymetric data, and comparing their biogeographic patterns. Four main evidences (i.e. different taxa; diver- gent taxa composition; different composition of biogeographic patterns; different endemicity rates) support that separation, especially in coastal benthic decapods; and these parametres combined would be used as a valuable tool at comparing biotas from oceanic archipelagos.

Twenty-three species of deep-water lobsters in the families Nephropidae, Palinuridae, Polychelidae and Scyllaridae are recorded from the continental shelf and slope off eastern Australia. Ten species and two genera have not been previously recorded from Australia. These are Acanthacaris tenuimana, Projasus parkeri, Polycheles baccatus, P. euthrix, P. granulatus, Stereomastis andamanensis, S. helleri, S. sculpta, S. suhmi and Willemoesia bonaspei. The deep­ water lobster fauna of eastern Australia is compared with those of other Indo-Pacific areas. A key is given to all deep-water lobster species recorded from Australian waters.

Michel Francois Marie Bermudes Abstract The aim of this project was to define more clearly the culture conditions for the propagation of the southern rock lobster (Jasus echvardsii) in relation to environmental bioenergetic constraints. The effects of temperature and photoperiod on the first three stages of development were first studied in small-scale culture experiments. Larvae reared at 18°C developed faster and reached a larger size at stage IV than larvae cultured at 14°C. Development through stage II was shorter under continuous light. However, the pattern of response to photoperiod shifted at stage III when growth was highest in all the light/dark phase treatments than under continuous light. The influence of temperature and light intensity in early-stage larvae was further investigated through behavioural and physiological studies. Results obtained in stages I, II and III larvae indicated an energetic imbalance at high temperature (-22°C).

  • Seasonal Variation in Community Structure and Recruitment of Benthic Decapods in a Sub-Tidal Cobble Habitat
    MARINE ECOLOGY PROGRESS SERIES Vol. 206: 181–191, 2000 Published November 3 Mar Ecol Prog Ser Seasonal variation in community structure and recruitment of benthic decapods in a sub-tidal cobble habitat Martin Robinson*, Oliver Tully Department of Zoology, Trinity College, Dublin, Ireland ABSTRACT: Quantitative suction samples of benthic decapod fauna were taken in the south of Ireland during 1997. Some species settled into the area, but failed to persist to the first winter, while others were present in high numbers throughout the year. The duration of settlement was species- specific, ranging from several weeks to several months. Body size at settlement decreased with increasing temperature during larval development. Growth potential and early mortality of a number of decapod species was examined by separation of successive moult instars from length-frequency distributions. Seasonal lows in abundance and biomass of young of the year and for previously estab- lished decapod individuals were identified at the end of July and early August, which may represent the most suitable time to release juveniles for stock-enhancement purposes. Community structure differed between settlement season and over-wintering periods. Young-of-the-year community structure differed from that of previously established individuals, with higher abundance and num- ber of species recorded for the former. The data represent a baseline study of a widely distributed community and may support further work on species interactions, improving the accuracy of predic- tion of annual recruitment fluctuations.
