This new taxon is supported by molecular evidence from a recent study of the newly described Caudalongidae Błażewicz &amp; Bird 2024. Arthrurids resemble tanaellids such as <i>Tanaella</i> Norman &amp; Stebbing, 1886 with their robust bodies, or <i>Arhaphuroides</i> Sieg, 1986 with their fused projecting uropod exopod, but also exhibit some agathotanaid-like features. These include the pereonite shape, pleon-pleotelson configuration, and pereopod morphology that are absent in the more diverse Tanaellidae, but arthrurids have a more plesiomorphic cheliped-cephalothorax articulation compared to those in the Agathotanaidae Lang, 1971. A large epignath seta, large coxal sclerite on the cephalothorax, and sticklike pereopods are among characters distinguishing the Arthruridae from most tanaellids. Two new genera are established, <i>Arthruropsis</i> n. gen. and <i>Paralibanius</i> n. gen., with the former tanaellid <i>Arhaphuroides bombus</i> Larsen, 2005, transferred to <i>Arthruropsis</i> n. gen. Six new species from bathyal New Zealand waters are described, <i>Libanius concertator</i> n. sp., <i>L. intonsus</i> n. sp., <i>L. largitas</i> n. sp., <i>L. projectus</i> n. sp., <i>L. tangaroa</i> n. sp., and <i>Paralibanius taitonga</i> n. sp., along with three from the southeastern Australia slope, <i>Libanius australis</i> n. sp., <i>L. brevicarpus</i> n. sp., and <i>L. clisicola</i> n. sp. We provide a key to the 13 known arthrurid species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A new deep-sea crustacean family of Tanaidacea is established from Aotearoa New Zealand and Southeast Australia based principally on morphology","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-04 01:31:55.465988","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-07-03","DateCreate":"2025-07-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-025-91383-4"},"refs":null,"anarec":{"AnaID":409418,"PubliDate":2025,"Pagination":"1-60","XtraPublOfAnaID":null,"ISBN":null,"Volume":"15","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
