  • Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an Assessment of Macaronesian and Cape Verde Biogeographic Marine Ecoregions

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.

The new species can be distin- guished from the only other species of the genus, H. granulata (Henderson, 1885), by the fewer spines on the dorsal carapace surface, the shape of the rostrum and supraocular spines, the antennal peduncles, and the length of the walking legs. Pairwise genetic distances estimated using the 16S rRNA and COI DNA gene fragments indicated high levels of sequence divergence between the new species and H. granulata. Phylogenetic analyses, however, recovered both species as sister species, supporting monophyly of the genus. Keywords Anomura, mitochondrial genes, morphology, West Pacific Introduction Squat lobsters of the family Munididae Ahyong, Baba, Macpherson & Poore, 2010 are recognised by the trispinose or trilobate front, usually composed of a slender rostrum flanked by supraorbital spines (Ahyong et al.

  • New Species Described from Specimens Collected As Part of the U.S
    New Species Described from Specimens Collected as Part of the U.S. Program on Biology of the International Indian Ocean Expedition 2 January 2020 Version A list was generated of the species described based on specimens collected as part of the U.S. Program on Biology of the International Indian Ocean Expedition. This list was compiled from a search of publications cited by scientists involved in the U.S. Program on Biology and publications held by the Smithsonian Institution. The list includes holotypes and paratypes used to describe species. The cruise information was checked against the list of known cruises of the R/V Anton Bruun and the R/V Te Vega given by Urban (2019a) and Urban (2019b). New genera and subspecies described are not reported. Each of the species names was checked in the World Register of Marine Species (http://marinespecies.org/) to verify the name and to determine whether the original name is still considered valid. Any changes in the species name are noted in footnotes. This list will be updated if additional species are found.

  • Allogalathea (Decapoda: Galatheidae): a Monospecific Genus of Squat Lobster?
    Zoological Journal of the Linnean Society, 2011, 162, 245–270. With 7 figures Allogalathea (Decapoda: Galatheidae): a monospecific genus of squat lobster? PATRICIA CABEZAS1*, ENRIQUE MACPHERSON2 and ANNIE MACHORDOM1 1Museo Nacional de Ciencias Naturales (CSIC), José Gutiérrez Abascal 2, 28006 Madrid, Spain 2Centro de Estudios Avanzados de Blanes (CSIC), Carr. Acc. Cala Sant Francesc 14, 17300 Blanes, Girona, Spain Received 8 March 2010; revised 14 June 2010; accepted for publication 16 June 2010 The genus Allogalathea was established by Baba in 1969 to include the well-known species Galathea elegans. This species is widely distributed across the Indo-West Pacific Ocean, and is characterized by living in close association with crinoids, and by its conspicuous coloration. Although the genus is considered monospecific, different colour patterns and discrete morphological variations mainly associated with the rostrum and chelipeds have been reported. These differences could point to cryptic species, thereby questioning Allogalathea as a monotypic taxon. To address this issue, we sequenced the mitochondrial cytochrome oxidase I (COI; 658 bp) and 16S rRNA (882 bp) genes and the nuclear gene phosphoenolpyruvate carboxykinase (PEPCK; 598 bp) in numerous specimens from eight different localities, and also examined their morphological characters. DNA sequences were analysed using maximum-parsimony, maximum-likelihood, and Bayesian approaches of phylogenetic inference. The resulting trees were combined with morphological evidence to test species boundaries. Our molecular data revealed four deeply divergent clades, which can be distinguished by subtle morphological differences in the spinulation and length- : breadth ratio of the P1 carpus, spinulation of the walking legs, and shape of the rostrum. Our findings indicated that Allogalathea elegans is in fact a species complex comprising four different species, which, although genetically very distinct, are morphologically very similar.

The collection consists of 26 species of 12 families. A new species of ethusid crab, Ethusina wakataka, is described and il- lustrated based on a male specimen from off Soma, Fukushima Prefecture, at depths of 1466̶1471 m. The new species can be distinguished from the known congeners primarily by the unique structure of the gonopods. The biogeography and the bathymetric distribution of the recorded species are briefl y discussed. Key words: Crustacea, Decapoda, Thalassinidea, Anomura, Brachyura, deep-sea, new species, Ethusina wakataka. Introduction Little has been published on the deep-water reptant decapods of the Pacifi c coast of northeast- ern Japan, although the area represents a major North Pacifi c fi shing ground.

Cienc. 38(146):88-92, enero-marzo de 2014 Ciencias naturales Primer registro de Munidopsis cubensis Chace, 1942 (Crustacea: Anomura: Munidopsidae) para el mar Caribe sur, Colombia Yeison Herrera-Medina, Adriana Bermúdez-Tobón, Gabriel R. Navas-Suárez* Programa de Biología, Facultad de Ciencias Exactas y Naturales, Universidad de Cartagena, Cartagena, Colombia Resumen Se registra la especie Munidopsis cubensis para el mar Caribe sur, Colombia, a partir de un espécimen recolectado con red de arrastre en noviembre de 2009, costa afuera de Punta Canoa (Bolívar), a 776 m de profundidad. Se presentan los caracteres diagnósticos de la especie y se añade información sobre su distribución y ámbitos batimétrico y geográfico. Con este nuevo registro se aumenta a 24 el número de especies deMunidopsis registradas para Colombia. Palabras clave: Munidopsis cubensis, Caribe, Colombia, Decapoda. First record of Munidopsis cubensis Chace, 1942 (Crustacea: Anomura: Munidopsidae) for the Southern Caribbean Sea, Colombia. Abstract Munidopsis cubensis is reported for the first time for the Southern Caribbean Sea, Colombia. The specimen was collected in November 2009, using a trawl, offshore of Punta Canoa (Bolívar) at a depth of 776 m. We present the species diagnostic characters, as well as its distribution and bathymetric and geographic information. This record increases to 24 the number of known species of Munidopsis in Colombia.
