Abstract: Knowledge of sea spider (Pycnogonida, Arthropoda) distribution and habitat preferences within Norwegian waters is scarce. During the MAREANO programme from 2007 to 2009, 3909 pycnogonid specimens representing 21 species and nine genera were collected. Pycnogonida were found at a total of 60 stations from 78 to 2609 m depth using van Veen grab, RP-sledge and beam trawl. Nymphon, the dominant genus, constituted 52% of the specimens sampled. Cilunculus battenae was recorded for the first time within Norwegian waters, and Pseudopallene longicollis was recorded for the first time in Norwegian Arctic waters (72°16′N, 14°36′E at ‒0.64°C). New records of Pseudopallene brevicollis, Boreonymphon robustum and B. ossiansarsi are reported. Boreonymphon abyssorum and Nymphon macronyx showed the widest depth ranges (100–2000 m depth). The known northern distribution of Callipallene producta was extended to 71°42′N, 15°25′E, Northern Norway. Two-thirds of the species found had their centre of distribution below 500 m and a species diversity maximum was found at 800–900 m. Four main species groups with different depth distributions were identified by cluster analysis: (1) shallow, above transition zone; (2) lower part of transition zone (transition zone is cold Norwegian Sea Arctic Intermediary Water (0.5 to −0.5°C) at 600 to 900 m depth); (3) lower transition zone, wide-ranging; and (4) mainly below 1000 m depth. A Detrended Correspondence Analysis supported the same pattern of clustering. © 2014, © 2014 Taylor & Francis.

The wood boring isopod, Sphaeroma terebrans is reported for the first time from Brunei coastal waters. The species was found inhabiting fallen wood, jetty piles, wooden poles of water villages and mangrove trees along the Brunei River estuary. Threats to the integrity of such structures and plants through the boring activities of this isopod have the potential for major economic and social impact in Brunei. © Marine Biological Association of the United Kingdom 2013.

The global zoogeographic distribution of the most widespread peracarid species occurring in three or more ocean basins below 2000 m is analysed. Basing on the published data we investigated 45 peracarid species, which have a most widespread distribution and most likely are cosmopolitan. Thirty-three species have a wide distribution in the Northern Hemisphere. Most species occur in the North Atlantic, however, 16 of these species occur also in the North Pacific, a more limited number of species occurs in the South Atlantic or South Pacific The Southern Ocean displays some special zoogeographic features and 22 widespread species occur there below 2000 m, including highly eurybathic ones. In total, 11 of the analysed species occur in all oceans. Eucopia australis (Lophogastrida), Munneury-cope murrayi (Isopoda) and Eurythenes gryllus (Amphipoda) are the species with the widest distributions. Other peracarids occurring in all oceans are: the isopods Paramunnopsis oceanica and Eurycope sarsi, the mysid Caesaromysis hispida the lophogastrid Eucopia unguiculata, the amphipod Mesopleustes abyssorum and the tanaids Exspina typica, Paranarthura insignis and Pseudotanais nordenskioldi. No cumacean species has been reported with an ocean-wide distribution but Campylaspis glabra occurs in the Atlantic, Indian and Pacific oceans. Among plenty of rare species in each order there are only few species with wide distribution records. There is evidence from molecular genetic studies that some of the widespread peracarids represent several cryptic species, however, some, e.g. Eucopia australis, seem to be truly cosmopolitan species. Geography of sampling is biasing our view of biogeography. The history and quality of taxonomic work as well as the reliability of geo- graphic records (quality control of large databases) limits our investigations of widespread or cosmopolitan species as much as the limited knowledge of variation within most species causes difficulties in defining morpho-species with certainty.

Three new genera, Acallocheirus, Aparatanais, and Penteparatanais, and seven new species of the paratanaid subfamily Paratanaidinae are described from New Zealand. New records of three previously known species Atemtanais taikaha, Paratanais paraoa, and P. tara, are also given. Paratanais denticulatus, P. intermedius, P. malignus, P. spinanotandus, and P. vicentetis are transferred to Aparatanais. A key is given to all paratanaidin genera and the NZ Paratanais species. In NZ waters, paratanaids are now known from the littoral zone to 908 m in the bathyal regions of the Chatham Rise and Hikurangi Margin, several of the offshore species being recorded in bryozoan mats. All but one appear to be endemic but may have sibling species elsewhere, particularly in the Southern Hemisphere. Supplementary notes are given on two Australian species P. maleficus and P. perturbatius that clarify their description and diagnostic characters. Copyright © 2013 Magnolia Press.
