Pseudodulichia , a New Genus of the Podoceridae from the Antarctic (Crustacea: Amphipoda: Gammaridea)
The systematic position of Dulichia antarctica R AUSCHERT , 1988 had to be revised. Some of its characters made it necessary to erect a new genus, Pseudodulichia gen. n., for this species.
First Discovery of the Family Cyproideidae (Crustacea : Amphipoda : Gammaridea) in the Magellanic Region
Victorhensenoides arntzi is described as a new genus and new species. The family Cyproideidae could not be detected before in Chilean waters. The study is based on material collected in the littoral of the Beagle Channel (southern tip of South A...

During the 26th Soviet Antarctic Expedition, 18 specimens of Priapulus tuberculatospinosus BAIRD, 1868 have been collected in 1981 to 1982 near King George Island, South Shetlands. Some essential characters of them...
An up-to-date catalogue of Antarctic and sub-Antarctic Phoxocephalidae is presented, including 35 species. Extensive list of bibliographical references with synonymy, detailed information on geographic and bathymetric distribution, ecological data, museum locations of type-material, remarks on taxonomic and biogeographical status, are provided for...

Bouvet (Bouvetøya) is a geologically young and very remote island just south of the Polar Front. Here we report samples taken
during the RV “Polarstern" cruise ANTXXI/2 on 3days in November 2003 and January 2004. This work was part of SCAR’s EASIZ
programme and intended, by providing data on the marine fauna of this “white gap" in the Atlantic sect...
Atyloella tribinicuspidata sp. n. was obtained and described from Agassiz trawl and dredging samples carried out in waters off Bouvet Island during
the FS “Polarstern” ANT XXI/2 expedition in November 2003. Atyloella tribinicuspidata is a very common amphipod species characteristic of the deeper sublittoral, from 122 m to 134 m water depth. Atyloel...

Gammaridean amphipods appear ubiquitous in the shelf communities of the eastern Weddell Sea where more than 230 species have been recorded. Comparison of catches of the 40 most common species taken by different gears and ethological observations in the aquarium allowed us to distinguish 6 groups: endobenthic, epibenthic, hyperbenthic (or suprabenth...
The family Artedidraconidae comprises small, endemic Antarctic fishes, known as plunderfish, mostly distributed in the High Antarctic region. To study the diet of these specialised benthic feeders, stomach contents of the II most abundant species in the eastern Weddell Sea were examined. Prey composition was identified to the lowest taxonomic level...
To investigate the marine benthic ecosystems of the Magellan region and to compare them with the better known Antarctic systems, three campaigns were recently carried out in this area: the Joint Magellan "Victor Hensen" Campaign 1994, the "Polarstern" ANT XIII/4 cruise 1996, and the "Vidal Gormaz" CIMAR FIORDO II cruise 1996. Numerous and diverse z...
E l ecosistema antártico está caracterizado por una notable estacionalidad de los procesos de producción biológica en la columna de agua. Durante el verano (cuando hay luz casi todo el día), los productores primarios se concentran en las ca-pas superficiales, para desaparecer el resto del año cuando escasean energía lumínica y nutrientes. Los episo...

To elucidate spatial assemblage patterns during 2 consecutive austral summer seasons, we sampled intensively the macrofauna
from 73 stations located at the southern coast of Livingston Island. Representatives of 28 higher taxonomic groups were used
for the faunal analysis. While two faunal descriptors (i.e. group richness and total biomass) changed...
Stenothoe magellanica sp. n. (Crustacea, Amphipoda, Gammaridea, Stenothoidae) from Magellanic South Chile.
Gonzalez (1991) lists 6 representatives of the family Stenothoidae for the Chilean Magellanic region. These species belong to the genera Metopoides, Probolisca and Torometopa (syn.: Metopoides). During the “Victor Hensen Cruise, 1994” on some...

During the "Victor Hensen Cruise, 1994" on some stations the new species Stenothoe magellanica could be found. Stenothoe magellanica sp. n. differs from th...
Stomacontion bulbus sp. n. (Crustacea, Amphipoda, Gammaridea, Lysianassidae) from the Maxwell Bay of King George Island (South Shetland Islands)
Stomacontion bulbus is described as new species from the littoral of King George Island. The study is based on material collected in depth about 80 to 90 m by dredge in the Maxwell Bay near Suffield Point...

Abstract A taxonomic study on stenothoid amphipods from the area of South Shetland Islands (Antarctica), led to the description ofThaumatelsonella kingelepha gen. and sp. nov. The systematic position ofPseudothaumatelson cyproides Nicholls, 1938 is discussed, as the redescription by Bellan-Santini & Ledoyer (1986) based on the first recovery of tha...

A new eusirid amphipod, Atylopsis fragilis n. sp., is described from material collected during investigations of the sublittoral fauna of Fildes Peninsula (south-western part of King George Island). The animals live in populations of high density in areas influenced by the rather violent tidal current between King George and Nelson Islands, in dept...
