The apseudomorphan tanaidaceans of the deep sea have been under-studied, especially in chemosynthetic habitats. A total of ten species present in the Gulf of Cadiz and the Horseshoe Continental Rise (SW off the Iberian Peninsula) are listed here, and new distribution data, ecological remarks and description of one new species of Atlantapseudes (Atlantapseudes curvatus sp. nov.) from recent research cruises are added. Pseudosphyrapus azorensis and Francapseudes uniarticulatus are recorded for the first time since the original descriptions. Notes on morphological development of Leviapseudes segonzaci and intraspecific variation of F. uniarticulatus are included, together with illustrations and descriptions of the material from the Gulf of Cadiz to complement previous descriptions.

The Tanaidacea collection from various research cruises carried out in the Gulf of Cadiz and Horseshoe Continental Rise between 2004 and 2012 yielded four species new to science that are described herein. Two belong to genera recorded for the first time since the original descriptions of their type species: Cetiopyge, described from the Gulf of Mexico and Gamboa from shallow waters of Macaronesia. The other two belong to the genera Collettea and Paragathotanais, both with a worldwide distribution. Additionally, specimens of Tumidochelia uncinata are described and illustrated to complete previous descriptions. Identification keys to all known genera of Nototanaidae, and the Eastern Atlantic species of Paragathotanais and Collettea are provided. This works raises the number of tanaidacean species known from the deep-sea habitats in the study region to a total of 22.

A New Species

Three leptostracan species (Crustacea: Phyllocarida) are reported from mud volcanoes at the Moroccan margin of the Gulf of Cadiz (NE Atlantic). Nebalia strausi Risso, 1826 and N. abyssicola Fage, 1929 were found in experimentally deployed organic substrates in Mercator, Meknès and Darwin mud volcanoes; N. abyssicola was also found among bathymodiolin bivalves and is recorded for the first time in the Atlantic Ocean. The third species was collected from the Gemini mud volcanoes and is described herein as Sarsinebalia ledoyeri sp. nov. The new species is characterised by having the eyes provided with ommatidia and lacking pigment, the ventral margin of the eye is concave along distal half, the antennular scale is more than twice as long as wide, the second article of the mandibular palp bears one seta on lateral surface about 0.5 times as long as the article and one subterminal seta longer than the third article, the distal article of the maxilla II endopod is about 1.8 times as long as the proximal article, the maxilla II exopod is clearly longer than the endopod proximal article, the lateral margin of the pleopod I exopod lacks setae and the posterodorsal border of pleonites VI–VII is provided with rounded to pointed denticles.

Abstract New records of 110 species of the acalyptrate Diptera family Agromyzidae are given from Portugal, including Madeira, Porto Santo and the Azores. A quarantine plant pest, Nemorimyza maculosa (Malloch, 1913), was detected in the Old World for the first time. Details on Phytobia xylem- miners and a parthenogenetic Phytomyza species are recorded together with new distribution data. For certain species morphological and taxonomic notes and discussions on known or new host plants are added. A complete checklist of Agromyzidae of Portugal is presented.

Published data forO. bruchi,O. rastratus,O. reticulatus,andO. vezenyiiare summarized. Two new species are described (O. bidentatusn. sp. andO. striatusn. sp.), and a key to the workers of the seven ParaguayanOxyepoecusspecies is provided. At Teniente Enciso National Park, four species cooccur. This locality appears as a promising site for studies documenting the biology of this poorly known ant genus, and because of the IUCN “vulnerable“ Red List classification ofO. inquilinus, the importance of the Teniente Enciso National Park for biological conservation is clearly established.

Five chrysopetalid species are reported from samples collected at bathyal depths in three NE Atlantic regions: the Bay of Biscay, the Horseshoe Abyssal Plain and the Gulf of Cadiz. Arichlidon reyssi (Katzmann et al., 1974), Dysponetus caecus (Langerhans, 1880) and D. profundus Böggemann, 2009 are free-living forms found mainly on biogenic substrates (e.g., coral and sunken wood). A brief description and taxonomical remarks are given for each of these species and their geographical distributions and habitat records were updated accordingly. Natsushima bifurcata Miura & Laubier, 1990 and Craseoschema thyasiricola gen. et sp. nov. are symbionts inhabiting the mantle cavity of chemosynthesis-based bivalves known from four mud volcanoes from the Gulf of Cadiz. Craseoschema thyasiricola gen. et sp. nov. was found inside a thyasirid bivalve and presents mixed morphological characteristics of free-living and symbiotic forms within Calamyzinae Hartmann-Schröder, 1971. A full description of the new species is given together with DNA sequences of the genes COI, 16S and H3 that were used in a phylogenetic analysis to indicate the position of the new genus within the family.

Abstract. New dinocyst analyses were conducted on core MD99-2339 retrieved from the central Gulf of Cadiz. Dinocyst and foraminiferal assemblages from this core are combined with existing data off SW Portugal and NW Morocco to investigate past hydrological and primary productivity regimes in the subtropical NE Atlantic Ocean over the last 30 ka. Our results have revealed highest upwelling intensity during Heinrich Stadial 1 (HS 1) and the Younger Dryas and weaker upwelling cells during the Last Glacial Maximum and HS 2, off the SW Iberian and NW Moroccan margins. Similar assemblages between Cadiz and Morocco and distinct species off Portugal were observed during the cold climatic extremes that punctuated the last 30 ka. This pattern has been linked to the occurrence of a hydrological structure between SW Iberia and Cadiz during the last glacial period, probably similar to the modern Azores Front. This front was probably responsible locally for heterotrophic dinocysts found in the Gulf of Cadiz during the last glacial period, even if this sector is not conductive to upwelling phenomena by Ekman transport. Regional reconstructions of paleo-sea-surface temperatures using dinocyst and foraminiferal transfer functions, as well as alkenones, are also discussed and depict coherent scenarios over the last 30 ka. However, some mismatches are observed between the different quantitative reconstructions such as during HS 1 in the Gulf of Cadiz and during the LGM at the three core locations.
