The former epimeriid genera <i>Actinacanthus</i> Stebbing, 1888 and <i>Paramphithoe</i> Bruzelius, 1859 are transferred to other families, respectively to the Acanthonotozomellidae Coleman &amp; J.L. Barnard, 1991 and the herein re-established Paramphithoidae G.O. Sars, 1883, so that only <i>Epimeria</i> and <i>Uschakoviella</i> Gurjanova, 1955 are retained within the Epimeriidae Boeck, 1871. The genera <i>Apherusa</i> Walker, 1891 and <i>Halirages</i> Boeck, 1891, which are phylogenetically close to <i>Paramphithoe</i> , are also transferred to the Paramphithoidae. The validity of the suborder Senticaudata Lowry &amp; Myers, 2013, which conflicts with traditional and recent concepts of Eusiroidea Stebbing, 1888, is questioned. Eight subgenera are recognized for Antarctic and sub-Antarctic species of the genus <i>Epimeria</i> : <i>Drakepimeria</i> subgen. nov., <i>Epimeriella</i> K.H. Barnard, 1930, <i>Hoplepimeria</i> subgen. nov., <i>Laevepimeria</i> subgen. nov., <i>Metepimeria</i> Schellenberg, 1931, <i>Pseudepimeria</i> Chevreux, 1912, <i>Subepimeria</i> Bellan-Santini, 1972 and <i>Urepimeria</i> subgen. nov. The type subgenus <i>Epimeria</i> , as currently defined, does not occur in the Southern Ocean. <i>Drakepimeria</i> species are superficially similar to the type species of the genus <i>Epimeria</i> : <i>E. cornigera</i> (Fabricius, 1779), but they are phylogenetically unrelated and substantial morphological differences are obvious at a finer level. Twenty-seven new Antarctic <i>Epimeria</i> species are described herein: <i>Epimeria (Drakepimeria) acanthochelon</i> subgen. et sp. nov., <i>E. (D.) anguloce</i> subgen. et sp. nov., <i>E. (D.) colemani</i> subgen. et sp. nov., <i>E. (D.) corbariae</i> subgen. et sp. nov., <i>E. (D.) cyrano</i> subgen. et sp. nov., <i>E. (D.) havermansiana</i> subgen. et sp. nov., <i>E. (D.) leukhoplites</i> subgen. et sp. nov., <i>E. (D.) loerzae</i> subgen. et sp. nov., <i>E. (D.) pandora</i> subgen. et sp. nov., <i>E. (D.) pyrodrakon</i> subgen. et sp. nov., <i>E. (D.) robertiana</i> subgen. et sp. nov., <i>Epimeria (Epimeriella) atalanta</i> sp. nov., <i>Epimeria (Hoplepimeria) cyphorachis</i> subgen. et sp. nov., <i>E. (H.) gargantua</i> subgen. et sp. nov., <i>E. (H.) linseae</i> subgen. et sp. nov., <i>E. (H.) quasimodo</i> subgen. et sp. nov., <i>E. (H.) xesta</i> subgen. et sp. nov., <i>Epimeria (Laevepimeria) anodon</i> subgen. et sp. nov., <i>E. (L.) cinderella</i> subgen. et sp. nov., <i>Epimeria (Pseudepimeria) amoenitas</i> sp. nov., <i>E. (P.) callista</i> sp. nov., <i>E. (P.) debroyeri</i> sp. nov., <i>E. (P.) kharieis</i> sp. nov., <i>Epimeria (Subepimeria) adeliae</i> sp. nov., <i>E. (S.) iota</i> sp. nov., <i>E. (S.) teres</i> sp. nov. and <i>E. (S.) urvillei</i> sp. nov. The type specimens of <i>E. (D.) macrodonta</i> Walker, 1906, <i>E. (D.) similis</i> Chevreux, 1912, <i>E. (H.) georgiana</i> Schellenberg, 1931 and E. (H.) inermis Walker, 1903 are re-described and illustrated. Besides the monographic treatment of Epimeriidae from the Southern Ocean, a brief overview and identification keys are given for their putative and potential relatives from the same ocean, i.e., the Antarctic and sub-Antarctic members of the following eusiroid families: Acanthonotozomellidae Coleman &amp; J.L. Barnard, 1991, Dikwidae Coleman &amp; J.L. Barnard, 1991, Stilipedidae Holmes, 1908 and Vicmusiidae Just, 1990. This overview revealed the existence of a new large and characteristic species of <i>Alexandrella</i> Chevreux, 1911, <i>A. chione</i> sp. nov. but also shows that the taxonomy of that genus remains poorly known and that several ‘variable widespread eurybathic species’ probably are species complexes. Furthermore, the genera <i>Bathypanoploea</i> Schellenberg, 1939 and <i>Astyroides</i> Birstein &amp; Vinogradova, 1960 are considered to be junior synonyms of <i>Alexandrella</i> . <i>Alexandrella mixta</i> Nicholls, 1938 and <i>A. pulchra</i> Ren <i>in</i> Ren &amp; Huang, 1991 are re-established herein, as valid species. It is pointed out that this insufficient taxonomic knowledge of Antarctic amphipods impedes ecological and biogeographical studies requiring precise identifications. Stacking photography was used for the first time to provide iconographic support in amphipod taxonomy, and proves to be a rapid and efficient illustration method for large tridimensionally geometric species. A combined morphological and molecular approach was used whenever possible for distinguishing <i>Epimeria</i> species, which were often very similar (albeit never truly cryptic) and sometimes exhibited allometric and individual variations. However in several cases, taxa were characterized by morphology only, whenever the specimens available for study were inappropriately fixed or when no sequences could be obtained. A large number of <i>Epimeria</i> species, formerly considered as eurybathic and widely distributed, proved to be complexes of species, with a narrower (overlapping or not) distribution. The distributional range of Antarctic <i>Epimeria</i> is very variable from species to species. Current knowledge indicates that some species from the Scotia Arc and the tip of the Antarctic Peninsula are narrow range endemics, sometimes confined to one island, archipelago, or ridge (South Georgia, South Orkney Islands, Elephant Island or Bruce Ridge); other species have a distribution encompassing a broader region, such as the eastern shelf of the Weddell Sea, or extending from the eastern shelf of the Weddell Sea to Adélie Coast. The most widely distributed species are <i>E. (D.) colemani</i> subgen. et sp. nov., <i>E. (E.) macronyx</i> (Walker, 1906), <i>E. (H.) inermis</i> Walker, 1903 and <i>E. (L.) walkeri</i> (K.H. Barnard, 1930), which have been recorded from the Antarctic Peninsula/South Shetland Islands area to the western Ross Sea. Since restricted distributions are common among Antarctic and sub-Antarctic <i>Epimeria</i> , additional new species might be expected in areas such as the Kerguelen Plateau, eastern Ross Sea, Amundsen Sea and the Bellingshausen Sea or isolated seamounts and ridges, where there are currently no <i>Epimeria</i> recorded. The limited distribution of many <i>Epimeria</i> species of the Southern Ocean is presumably related to the poor dispersal capacity in most species of the genus. Indeed with the exception of the pelagic and semi-pelagic species of the subgenus <i>Epimeriella</i> , they are heavy strictly benthic organisms without larval stages, and they have no exceptional level of eurybathy for Antarctic amphipods. Therefore, stretches deeper than 1000 m seem to be efficient geographical barriers for many <i>Epimeria</i> species, but other isolating factors (e.g., large stretches poor in epifauna) might also be at play. The existence of endemic shelf species with limited dispersal capacities in the Southern Ocean (like many <i>Epimeria</i> ) suggests the existence of multiple ice-free shelf or upper slope refugia during the Pleistocene glaciations within the distributional and bathymetric range of these species. Genera with narrow range endemics like <i>Epimeria</i> would be excellent model taxa for locating hotspots of Antarctic endemism, and thus potentially play a role in proposing meaningful Marine Protected Areas (MPAs) in the Southern Ocean.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>Epimeria</i> of the Southern Ocean with notes on their relatives (Crustacea, Amphipoda, Eusiroidea)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:59.120087","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Southern Ocean","OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-10-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000413187600001","VABBcode":null,"OpenAcc":1,"DOI":"10.5852/ejt.2017.359"},"refs":null,"anarec":{"AnaID":290051,"PubliDate":2017,"Pagination":"1-553","XtraPublOfAnaID":null,"ISBN":null,"Volume":"359","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":215336,"SerRR":"European Journal of Taxonomy.
