Published online at www.arthropod-systematics.de on 25.viii.2009. > Abstract Phylogenetic relationships between the basal (or less derived) families in the tanaidacean superorder Paratanaoidea are examined and their monophyly tested using evidence derived from external morphology. With the genus Zeuxoides from the superfamily Tanaidoidea as outgroup, monophyly is confi rmed for the Paratanaidae, Pseudotanaidae, Pseudozeuxidae, and Typhlotanaidae. The subfamily Teleotanainae is raised to family status to accommodate the genus Teleotanais. The monophyly of Leptocheliidae s.str. is accepted but several taxa are not included, neither is monophyly verifi ed for Hetero- tanainae and Leptocheliinae. Nototanaidae appears to be polyphyletic and is split into Nototanaidae s.str. and Tanaissuidae fam. nov. Cryptocopidae is recognized but with exclusion of the Iungentitanainae; otherwise, this family is left for later analysis, including more derived taxa. Protanaissus, Leptochelia, Pseudoleptochelia and Pseudonototanais all appear to be non-monophyletic and will need revisions, while Antiplotanais, Grallatotanais, Metatanais, and Tangalooma are considered ‘fl oating’ taxa, albeit close to existing family-level clades. Initial attempts to include the derived tanaidacean families proved inconclusive and this suggests that limited phylogenetic analyses of the Paratanaoidea are necessary. We here suggest a re- vised method – the ‘Restricted taxa analysis’ – for resolving diffi cult datasets of the ‘many-taxa-few-characters’ type. This study should be regarded as a platform for more comprehensive analyses and systematic conclusions for the Tanaidacea. > Key words Phylogenetic analysis, Tanaidacea, plesiomorphic Tanaidomorpha, Tanaissuidae, Teleotanaidae, Restricted taxa analysis. 1.

The material was collected during 12 summer expeditions organized from Diversity; 1997 to 2013. In all, 24 pelagic and 116 benthic taxa were recorded, most of them widely Distribution distributed Arctic-boreal species. The advection of different water masses from the shelf had a direct impact on the structure of the pelagic Malacostraca communities, resulting in the clear dominance of the sub-arctic hyperiid amphipod Themisto abyssorum in Kongsfjorden and the great abundance of Decapoda larvae in Hornsund. The taxonomic, functional and size compositions of the benthic malacostracan assemblages varied between the two fjords, and also between the glacier-proximate inner bays and the main fjord basins, as a result of the varying dominance patterns of the same assemblage of species. There was a significant drop in species richness in the strongly disturbed glacial bays of both fjords, but only in Hornsund was this accompanied by a significant decrease in density and diversity, probably due to greater isolation and poorer quality of sediment organic matter in its innermost basin.

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)* ANGELIKA BRANDT Zoological Institute and Zoological Museum, Martin-Luther-King-Platz 3, D-20146 Hamburg, Germany Dedicated to Jürgen Sieg, who silently died in 1996. He inspired this research with his important account of the zoogeography of the Antarctic Tanaidacea. SUMMARY: The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary his- tory of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension feeders on the continental shelf, favoured evolutionary processes of “preadapted“ taxa, like for exam- ple the Peracarida. This taxon performs brood protection and this might be one of the most important reasons why it is very successful (i.e. abundant and diverse) in most terrestrial and aquatic environments, with some species even occupying deserts. The extinction of many decapod crustaceans in the Cenozoic might have allowed the Peracarida to find and use free ecological niches. Therefore the palaeogeographic, palaeoclimatologic, and palaeo-hydrographic changes since the Palaeocene (at least since about 60 Ma ago) and the evolutionary success of some peracarid taxa (e.g. Amphipoda, Isopo- da) led to the evolution of many endemic species in the Antarctic. Based on a phylogenetic analysis of the Antarctic Tanaidacea, Sieg (1988) demonstrated that the tanaid fauna of the Antarctic is mainly represented by phylogenetically younger taxa, and data from other crustacean taxa led Sieg (1988) to conclude that the recent Antarctic crustacean fauna must be comparatively young.

Yet they have no obligate dispersive phase in their life-cycle. Populations are thus inevitably isolated, and allopatric speciation and high regional diversity are inevitable; cosmopolitan distributions are considered to be unlikely or non-existent.

The species has been recorded from five different water bodies in the Dutch coastal area and in the docks of the Belgian harbour of Antwerp.

  • A Tip of the Iceberg—Pseudotanaidae (Tanaidacea) Diversity in the North Atlantic
    Marine Biodiversity (2018) 48:859–895 https://doi.org/10.1007/s12526-018-0881-x BIODIVERSITY OF ICELANDIC WATERS A tip of the iceberg—Pseudotanaidae (Tanaidacea) diversity in the North Atlantic Aleksandra Jakiel1 & Anna Stępień1 & Magdalena Błażewicz1 Received: 13 October 2017 /Revised: 20 March 2018 /Accepted: 21 March 2018 /Published online: 3 May 2018 # The Author(s) 2018 Abstract During two IceAGE expeditions, a large collection of Tanaidacea was gathered from the shelf down to the slope (213−2750 m) in six areas off Iceland—the Irminger Basin, the Iceland Basin, the Norwegian Sea, the Denmark Strait, the Iceland-Faroe Ridge, and the Norwegian Channel. In this collection, members of the family Pseudotanaidae were most numerous component. We examined 40 samples collected with different gears (e.g., EBS, VVG. GKG), in which 323 pseudotanaid individuals were counted and covered a total depth from 213.9 to 2746.4 m. Morphological identification of the material has revealed the presence of five species: Akanthinotanais cf. longipes, Mystriocentrus biho sp. n. Pseudotanais misericorde sp. n., P. svavarssoni sp. n., and P. sigrunis sp. n. The description of the four new species has been presented in the paper and a rank of the subgenus Akanthinotanais is elevated to a genus rank. A large group of morphologically almost identical specimens, similar with P. svavarssoni sp. n. from a wide depth range and from various areas off Iceland was discriminated to species by applying morphometric methods; one distinct species (P. svavarssoni sp. n.) and complex of presumably cryptic species the species was discovered. Based on current data and literature records, similarity among fauna of Pseudotanaidae was assessed with applying Bray–Curtis formula.
