  • Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an Assessment of Macaronesian and Cape Verde Biogeographic Marine Ecoregions
    Zootaxa 4413 (3): 401–448 ISSN 1175-5326 (print edition) http://www.mapress.com/j/zt/ Article ZOOTAXA Copyright © 2018 Magnolia Press ISSN 1175-5334 (online edition) https://doi.org/10.11646/zootaxa.4413.3.1 http://zoobank.org/urn:lsid:zoobank.org:pub:2DF9255A-7C42-42DA-9F48-2BAA6DCEED7E Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an assessment of Macaronesian and Cape Verde biogeographic marine ecoregions JOSÉ A. 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.

  • First Record of Dromia Neogenica Müller, 1979 (Decapoda, Brachyura, Dromiidae) from Neogene Strata in the Southern North Sea Basin
    FIRST RECORD OF DROMIA NEOGENICA MÜLLER, 1979 (DECAPODA, BRACHYURA, DROMIIDAE) FROM NEOGENE STRATA IN THE SOUTHERN NORTH SEA BASIN BY RENÉ H.B. FRAAIJE1,4), BARRY W.M. VAN BAKEL1,2,5) and JOHN W.M. JAGT3,6) 1) Oertijdmuseum De Groene Poort, Bosscheweg 80, NL-5283 Boxtel, The Netherlands 2) Nederlands Centrum voor Biodiversiteit (Naturalis), P.O. Box 9517, NL-2300 RA Leiden, The Netherlands 3) Natuurhistorisch Museum Maastricht, de Bosquetplein 6-7, NL-6211 KJ Maastricht, The Netherlands ABSTRACT The sponge crab Dromia neogenica Müller, 1979 (Dromiidae) is recorded for the first time from strata of Neogene (late Miocene-early Pliocene) age in the southern North Sea Basin, on the basis of two concretion-preserved carapaces from Bemmel (north of Nijmegen, province of Gelderland, The Netherlands). The presence of this species, which was previously known from the middle-upper Miocene of Hungary and Algeria, suggests relatively higher seawater temperatures in the North Sea during the late Miocene-early Pliocene. Morphological differences (extraorbital and anterolateral teeth, development of cervical and branchiocardiac grooves) between D. neogenica and extant D. personata (Linnaeus, 1758) are relatively minor. This observation, coupled with the absence of the former species in mid-Pliocene and younger strata, and with the robust record of the latter in the mid-Pliocene to upper Pleistocene of Italy, would indicate that D. neogenica and D. personata are closely related, and probably represent the same lineage. RÉSUMÉ La dromie éponge Dromia neogenica Müller, 1979 (Dromiidae) est signalée pour la premiére fois dans les strates du Néogène (fin du Miocène-début du Pliocène) du sud du bassin de la mer du Nord.

  • Os Nomes Galegos Dos Moluscos
    A Chave Os nomes galegos dos moluscos 2017 Citación recomendada / Recommended citation: A Chave (2017): Nomes galegos dos moluscos recomendados pola Chave. http://www.achave.gal/wp-content/uploads/achave_osnomesgalegosdos_moluscos.pdf 1 Notas introdutorias O que contén este documento Neste documento fornécense denominacións para as especies de moluscos galegos (e) ou europeos, e tamén para algunhas das especies exóticas máis coñecidas (xeralmente no ámbito divulgativo, por causa do seu interese científico ou económico, ou por seren moi comúns noutras áreas xeográficas). En total, achéganse nomes galegos para 534 especies de moluscos. A estrutura En primeiro lugar preséntase unha clasificación taxonómica que considera as clases, ordes, superfamilias e familias de moluscos. Aquí apúntase, de maneira xeral, os nomes dos moluscos que hai en cada familia. A seguir vén o corpo do documento, onde se indica, especie por especie, alén do nome científico, os nomes galegos e ingleses de cada molusco (nalgún caso, tamén, o nome xenérico para un grupo deles). Ao final inclúese unha listaxe de referencias bibliográficas que foron utilizadas para a elaboración do presente documento. Nalgunhas desas referencias recolléronse ou propuxéronse nomes galegos para os moluscos, quer xenéricos quer específicos. Outras referencias achegan nomes para os moluscos noutras linguas, que tamén foron tidos en conta. Alén diso, inclúense algunhas fontes básicas a respecto da metodoloxía e dos criterios terminolóxicos empregados. 2 Tratamento terminolóxico De modo moi resumido, traballouse nas seguintes liñas e cos seguintes criterios: En primeiro lugar, aprofundouse no acervo lingüístico galego. A respecto dos nomes dos moluscos, a lingua galega é riquísima e dispomos dunha chea de nomes, tanto específicos (que designan un único animal) como xenéricos (que designan varios animais parecidos).
