During these studies, a new species of Ampharetidae Malmgren, 1867, <em>Anobothrus konstantini</em> Säring & Bick sp. nov., was found. Here we present a detailed description of this species. We used the traditional light microscope and scanning electron microscope (SEM) to identify and describe the diagnostic characters: a circular glandular band on segment 6; an elongate ridge between the notopodia on segment 12 and modified notochaetae on this segment; 16 thoracic, two intermediate and ten abdominal segments. For the first time, micro-computed tomography (micro-CT) was used for a species description of <em>Anobothrus</em>. Micro-CT provided information on the shape of the prostomium (<em>Ampharete</em>-type) and the arrangement of branchiae (four pairs in two rows, without a gap). In addition, we provide quantitative information on the environmental niche based on sediment parameters (chlorophyll <em>a</em> content, organic matter content, chloroplast equivalent, grain size) for the new <em>Anobothrus</em> species, relevant for, e.g., species distribution modelling. Finally, an identification key for all <em>Anobothrus</em> species is provided.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A new species of Anobothrus (Polychaeta, Ampharetidae) from the Weddell Sea (Antarctica), with notes on habitat characteristics and an updated key to the genus","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-09 01:32:21.645720","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Anobothrus konstantini Säring & Bick sp. nov.; Antarctic Peninsula; ecology; Filchner Trough; micro-CT analysis; SEM","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-10-06","DateCreate":"2022-04-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000765491400001","VABBcode":null,"OpenAcc":1,"DOI":"10.5852/ejt.2022.789.1637"},"refs":null,"anarec":{"AnaID":350991,"PubliDate":2022,"Pagination":"130-152","XtraPublOfAnaID":null,"ISBN":null,"Volume":"789","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":215336,"SerRR":"European Journal of Taxonomy.
