The three species are morphologically consistent with the present broad concept of the genus <i>Bucephalus</i> Baer, 1827, but significant phylogenetic and ecological differences relative to the type-species of <i>Bucephalus</i> require the proposal of a new genus. <i>Aenigmatrema</i> n. g. is proposed for <i>A. undecimtentaculatum</i> n. sp. (type-species), <i>A. inopinatum</i> n. sp. and <i>A. grandiovum</i> n. sp. In addition, based on morphological, ecological and biogeographical similarities, we recombine two existing species of <i>Bucephalus</i> as <i>Aenigmatrema kaku</i> (Yamaguti, 1970) n. comb. and <i>Aenigmatrema sphyraenae</i> (Yamaguti, 1952) n. comb. Although the three species described in this study are extremely morphologically similar, they can be differentiated from each other, and from <i>A. kaku</i> and <i>A. sphyraenae</i>, morphometrically on the basis of egg size, tentacle number and a combination of the caecum and vitelline field lengths. Complete ITS2 rDNA, partial 28S rDNA and partial <i>cox</i>1 mtDNA sequence data were generated for the three new species, which formed a well-supported clade in all 28S phylogenetic analyses. An expanded phylogenetic tree for the subfamily Bucephalinae Poche, 1907 is presented, demonstrating unresolved issues with the morphology-based taxonomy of the subfamily. The three largest genera, <i>Bucephalus</i>, <i>Rhipidocotyle</i> Diesing, 1858 and <i>Prosorhynchoides</i> Dollfus, 1929 remain extensively polyphyletic, indicating the need for significant further systematic revision.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A new genus of Bucephalidae Poche, 1907 (Trematoda: Digenea) for three new species infecting the yellowtail pike, <i>Sphyraena obtusata</i> Cuvier (Sphyraenidae), from Moreton Bay, Queensland, Australia","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-24 01:32:59.394896","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-09-01","DateCreate":"2020-09-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000559472600001","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s11230-020-09931-7"},"refs":null,"anarec":{"AnaID":328427,"PubliDate":2020,"Pagination":"455-476","XtraPublOfAnaID":null,"ISBN":null,"Volume":"97","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43948,"SerRR":"Systematic Parasitology.
