A new and rare species of Entoprocta from the Southern Ocean, its abundance, habitat and possible commensal relationship with Polychaeta are presented. During the RV <i>Polarstern</i> expedition PS118 (2019) to the northwestern Weddell Sea, sediment samples were taken with a multicorer. The species of the family Loxosomatidae was discovered in the meiofauna size fraction of samples of only one of three investigated stations (413–415&nbsp;m depth). <i>Loxosomella sigridae</i> sp. nov. is a solitary, medium-sized entoproct (total length up to 773&nbsp;µm). Decisive characters of the adult include twelve tentacles, an aborally situated Y-shaped cell row, paired accessory gland cells along the foot groove and smooth adhesive papillae at the tip of the foot. The reproductive cycle of <i>Loxosomella sigridae</i> sp. nov. has a sexual and an asexual phase via larvae and bud-carrying individuals, respectively. We present confocal laser-scanning images of both developmental stages. Integrative methods are used to describe the habitat of <i>Loxosomella sigridae</i> sp. nov. and gain insight in its relationship to possible host organisms. We discuss co-occurring polychaete families and their ecology and conclude that Cirratulidae and/or Paraonidae may most likely be the hosts of <i>Loxosomella sigridae</i> sp. nov.<h3 style=\"margin-left:0px;\">&nbsp;</h3>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A new Entoprocta species from the northwestern Weddell Sea shelf (Southern Ocean), its soft-sediment habitat and possible polychaete hosts","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-27 01:32:27.184081","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Kamptozoa, taxonomy, meiobenthos, infaunal lifestyle, Southern Ocean, continental shelf, <i>Loxosomella sigridae</i>","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2024-11-28","DateCreate":"2024-11-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s00300-024-03304-2"},"refs":null,"anarec":{"AnaID":404487,"PubliDate":2024,"Pagination":"1593-1608","XtraPublOfAnaID":null,"ISBN":null,"Volume":"47","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
