Abstract The crustacean marine isopod species Haploniscus bicuspis (Sars, 1877) shows circum‐Icelandic distribution in a wide range of environmental conditions and along well‐known geographic barriers, such as the Greenland‐Iceland‐Faroe (GIF) Ridge. We wanted to explore population genetics, phylogeography and cryptic speciation as well as investigate ...

MITOCHONDRIAL GENES AND ISOPOD PHYLOGENY (PERACARIDA: ISOPODA) [PDF]
Abstract Molecular data are used to test whether (1) Phreatoicidea are the earliest derived living isopods, and (2) the long-tailed isopod morphology is the derived condition within the Isopoda. Small and large subunits of the mitochondrial ribosomal genes (12S- and 16S rDNA), and cytochrome oxidase c subunit I (COI) are used as a case study for ...

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)
The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary history of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension ...

Nuuanu beatricis n. sp., a new melitid amphipod, is described from shallow-water sandy bottoms on the S and SE coasts of Mallorca (Balearic Islands, Mediterranean). It differs from the rest of its congeners in the combination of: (1) non-geniculate

Paleozoic cumaceans (Crustacea, Malacostraca, Peracarida) from North America [PDF]
Three new species of malacostracans are described from North America in the Upper Mississippian Into Formation of Arkansas, and the Pennsylvanian Eudora Shale of southeastern Kansas. These appear to be the oldest fossils attributed to the Cumacea and are only the third collection of fossil cumaceans anywhere to be described.
