The palaeacanthocephalan <i>Metarhadinorhynchus</i> Yamaguti, 1959 and its type species <i>M. lateolabracis</i> Yamaguti, 1959 are such to-be-explored taxa. We aim to refne (i) the systematic placement, (ii) the morphological circumscription, and (iii) the taxonomic components of the genus. We also aim to examine the taxonomic status of the species that have been assigned to the genus.Methods: Morphological observations on newly collected specimens as well as the type material of <i>Metarhadinorhyn?chus lateolabracis</i> were conducted. Also, molecular phylogenetic analyses with maximum-likelihood method and Bayesian inference were performed based on freshly collected specimens. Nominal species that have at least once been assigned in <i>Metarhadinorhynchus</i>, as well as a related form, <i>Gorgorhynchus lateolabri</i> Yin and Wu, 1984, are taxonomically re-evaluated based on literature information.Results: Our re-examination of the type material of <i>M. lateolabracis</i> revealed that the number of cement glands is six, instead of eight as described and illustrated in the original description. In the resulting phylogenetic tree, <i>M. lateolabracis</i> was nested in Isthmosacanthidae. <i>Gorgorhynchoides</i> Cable and Linderoth, 1963 was found to be a junior synonym of <i>Metarhadinorhyn?chus</i>. Taxonomic re-evaluations of six nominal species that have once belonged in <i>Metarhadinorhynchus</i> led to modifcations of generic diagnoses for<i> Indorhynchus</i> Golvan, 1969 and <i>Neotegorhynchus</i> Lisitsyna, Xi, Orosová, Barčák, and Oros, 2022.Conclusions <i>Metarhadinorhynchus </i>has been assigned to Leptorhynchoididae (Echinorhynchida), but our study now locates it in Isthmosacanthidae (Polymorphida). We propose 13 new combinations of specifc names in <i>Metarhadinorhynchus</i> and three in <i>Indorhynchus. Metarhadinorhynchus lateolabri</i> (Yin and Wu, 1984) comb. nov. may be synonymous with <i>M. ori?entalis </i>(Wang, 1966) comb. nov.&nbsp;","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Molecular systematics and type-material-based redescription of <i>Metarhadinorhynchus lateolabracis</i>, with taxonomic revisions of <i>Metarhadinorhynchus, Indorhynchus</i>, and <i>Neotegorhynchus</i> (Acanthocephala: Palaeacanthocephala)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-29 01:33:07.348940","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Molecular phylogeny, Morphology, Echinorhynchida, Polymorphida, seabass","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2024-11-12","DateCreate":"2024-11-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s11686-024-00876-1"},"refs":null,"anarec":{"AnaID":396539,"PubliDate":2024,"Pagination":"1411-1425","XtraPublOfAnaID":null,"ISBN":null,"Volume":"69","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":76478,"SerRR":"Acta Parasitologica.
