A new genus and species of oceanic planktonic Tisbidae (Crustacea, Copepoda, Harpacticoida) with enlarged modified eyes.

Both sexes of a new monotypic genus of Tisbidae (Copepoda, Harpacticoida) are described from the epi- or mesopelagic zone in the Kuroshio region, Japan. belongs to a monophyletic lineage of deepwater holoplanktonic genera defined by a suite of characters. Within this clade, appears most closely related to Boxshall, 1979.

Diversity, habitat endemicity and trophic ecology of the fauna of Loki's Castle vent field on the Arctic Mid-Ocean Ridge.

Loki's Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not yet been published, hindering the inclusion of the Arctic in biogeographic analyses of vent fauna. There is an urgent need to understand the diversity, spatial distribution and ecosystem function of the biological communities along the AMOR, which will inform environmental impact assesments of future deep-sea mining activities in the region.

John Berkeley James WellsAn appreciation of his contributions to harpacticoid diversity and systematics.

John Wells was born in Hammersmith, a district in west London, where he spent most of his childhood and teenage life. It was a surprise to find out only recently that he had received a scholarship to Latymer Upper School on King Street which is literally one block away from where I used to live when I started working at the Natural History Museum in the early 1990s. The site has a long history and can be traced to a charity school founded in 1624 by the English merchant Edward Latymer, a wealthy lawyer and puritan, who left part of his wealth for the clothing and education of eight poore boyes from Hammersmith.

Parasites, pathogens, and other symbionts of copepods.

There is a large diversity of eukaryotic symbionts of copepods, dominated by epizootic protists such as ciliates, and metazoan parasites. Eukaryotic endoparasites, copepod-associated bacteria, and viruses are less well known, partly due to technical limitations. However, new molecular techniques, combined with a range of other approaches, provide a complementary toolkit for understanding the complete symbiome of copepods and how the symbiome relates to their ecological roles, relationships with other biota, and responses to environmental change.

New species from the Bohai Sea, China, re-evaluation of the validity of Kornev & Chertoprud, 2008 and proposal of gen. n. (Copepoda, Harpacticoida, Canthocamptidae).

Two new species of the genus Por, 1960 (Canthocamptidae) are described from the Bohai Sea, eastern China. and differ from their congeners by the presence of two instead of three outer spines on P2-P3 exp-3. They can be differentiated from each other by (1) number of inner setae on P3-P4 enp-2; (2) anterior margin of antennulary segment 7 of male; (3) ornamentation of male abdomen; (4) sexual dimorphism on P2 endopod and P3-P4 exp-3; and (5) differences in length of setae on male P5.

Harpacticoid copepods-their symbiotic associations and biogenic substrata: a review.

Members of the order Harpacticoida are primarily free-living and benthic but some lineages have adopted alternative modes of life which involve a major habitat shift or dependence on a host. Since the first discovery of a harpacticoid associated with an invertebrate host about 150 years ago, a total of 172 species, representing 84 genera and 17 families, have been shown to live in symbiotic partnership with other organisms. The steady addition of new taxa during the last 35 years testifies to the widespread and previously underestimated occurrence of symbiosis in the group.

Enigmas from the past: M'Intosh's (1885) annelidicolous copepods from the voyage of H.M.S. Challenger.

The type material of four monotypic genera, Leaniricola, Oestrella, Praxillinicola and Trophoniphila (Copepoda, Cyclopoida), described by M'Intosh (1885) from deep water polychaete hosts collected during the H.M.S.

Copepods associated with scleractinian corals: a worldwide checklist and a case study of their impact on the reef-building coral Pocillopora damicornis (Linnaeus, 1758) (Pocilloporidae).

The Cnidaria have more symbiotic copepods than any other group of invertebrates, and the greatest numbers of these associates occur on hard corals. A review of the scattered literature on the diversity and taxonomic composition of scleractinian-associated copepods and their hosts revealed a total of 148 coral species, representing 66 genera and 15 families that serve as hosts to copepods. At present, 363 copepod species, representing 99 genera, 19 families and three orders, have been recorded as associates of scleractinian corals.

Prof. Il-Hoi Kim: a tribute.

Prof. Il-Hoi Kim was born during the Korean War on 28 February 1952 in Buan, North Jeolla Province (South Korea), near the coast of the Yellow Sea whose tidal flats would become one of his favourite sampling grounds during his scientific career. From an early age he developed an intense interest in natural history in general and marine biology in particular.

Preface: Recent Developments in Taxonomy and Biodiversity of Symbiotic Copepoda (Crustacea)-A Volume in Celebration of the Career of Prof. Il-Hoi Kim.

Symbiosis is one of the most successful modes of life displayed by aquatic organisms, as measured by the number of times it evolved and how many symbiotic species are presently in existence. Among the Crustacea copepods utilize an extraordinary range of hosts, occurring on virtually every phylum of marine macroinvertebrates and, jointly with the monogeneans, are the most speciose group of metazoan ectoparasites of marine fishes (Rhode 2005). Several species have a major impact on global finfish and shellfish aquaculture, causing significant effects on farm production, economic viability and sustainability (Shinn et al.

Early Miocene amber inclusions from Mexico reveal antiquity of mangrove-associated copepods.

Copepods are aquatic microcrustaceans and represent the most abundant metazoans on Earth, outnumbering insects and nematode worms. Their position of numerical world predominance can be attributed to three principal radiation events, i.e.

On two reports associated with James Wood-Mason and Alfred William Alcock published by the Indian Museum and the Indian Marine Survey between 1890 and 1891: implications for malacostracan nomenclature.

Two rare documents associated with the Indian Museum and the Indian Marine Survey for the administrative year April 1890 to March 1891 have been examined and found to have nomenclatural consequences for malacostracan crustaceans. Even though they constitute available published works according to the International Code for Zoological Nomenclature, these reports have rarely been cited. Dating these two publications is of importance as they make decapod scientific names available and, in a few instances, describe the same taxa.

Sabelliphilidae (Copepoda: Cyclopoida) associated with the tube anemone Pachycerianthus maua (Carlgren) and the horseshoe worm Phoronis australis Haswell off New Caledonia.

Examination of washings of the ceriantharian Pachycerianthus maua (Carlgren) and its phoronid symbiont Phoronis australis Haswell in New Caledonian waters revealed two species of symbiotic copepods belonging to the family Sabelliphilidae (Cyclopoida). Phoronicola spinulatus Boxshall & Humes, 1988, the only other copepod known to be associated with a phoronid and originally described from Hong Kong, was found on both the lophophore of Phoronis australis and the tentacular crown of Pachycerianthus maua. Both sexes of Phoronicola spinulatus are redescribed based on the New Caledonian material and re-examination of the type-material revealed some observational errors in the original description.

Evolution of the bomolochiform superfamily complex (Copepoda: Cyclopoida): new insights from ssrDNA and morphology, and origin of Umazuracolids from polychaete-infesting ancestors rejected.

Poecilostome cyclopoids are among the most morphologically diverse copepods, having established symbiotic relationships with teleosts, elasmobranchs and invertebrate hosts belonging to no fewer than 14 marine phyla. Many parasitic lineages display radically divergent body plans and on that basis have traditionally been placed at higher taxonomic rank than they deserve. The most recent example is the monotypic family Umazuracolidae, established for a derived fish parasite with bomolochiform affinities.

Crustaceans from bitumen clast in Carboniferous glacial diamictite extend fossil record of copepods.

Copepod crustaceans are extremely abundant but, because of their small size and fragility, they fossilize poorly. Their fossil record consists of one Cretaceous (c. 115 Ma) parasite and a few Miocene (c.
