As adults, all 3 species infect rabbitfishes (Siganidae: <jats:italic>Siganus<\/jats:italic>). New collections from 11 species of <jats:italic>Siganus<\/jats:italic> from northern Australia, Indonesia, New Caledonia, French Polynesia, Palau and Japan enabled an exploration of species composition within this genus. Phylogenetic analyses demonstrate a deep distinction between 2 major clades; clade 1 comprises most of the sequences of specimens from Australia as well as all of those from Japan, Palau and New Caledonia and clade 2 comprises all sequences of specimens from French Polynesia, 2 sequences from Australia and the single sequence from Bali. In all analyses, both major clades have genetic structuring leading to distinct geographic lineages. Morphologically, specimens relating to clades 1 and 2 differ but overlap in body shape, oral sucker and egg size. Principle component analysis shows a general (but not complete) separation between specimens relating to the 2 clades. We interpret the 2 clades as representing 2 species: clade 1 is identified as <jats:italic>E. fusum<\/jats:italic> and is reported in this study from 10 species of siganids from Australia, Japan, Palau and New Caledonia; clade 2 is described as <jats:italic>E. gotozakiorum<\/jats:italic> n. sp., for all specimens from French Polynesia and rare specimens from Australia and Indonesia. We recognize <jats:italic>E. sigani<\/jats:italic> as a junior synonym of <jats:italic>E. fusum<\/jats:italic>. Although species of <jats:italic>Emprostiotrema<\/jats:italic> occur widely in the tropical Indo-Pacific, they have not been detected from Ningaloo Reef (Western Australia), the southern Great Barrier Reef or Moreton Bay (southern Queensland).<\/jats:p>","DOI":"10.1017\/s0031182024001252","type":"journal-article","created":{"date-parts":[[2024,11,20]],"date-time":"2024-11-20T07:36:46Z","timestamp":1732088206000},"page":"1336-1350","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":6,"title":["Taxonomy and systematics of <i>Emprostiotrema<\/i> Cianferoni and Ceccolini, 2021 (Digenea: Emprostiotrematidae), parasites of rabbitfish (Siganidae) from the Indo-West Pacific marine region"],"prefix":"10.1017","volume":"151","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1015-4703","authenticated-orcid":false,"given":"Daniel C.","family":"Huston","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott C.","family":"Cutmore","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1092-9705","authenticated-orcid":false,"given":"Thomas H.","family":"Cribb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Sasal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell Q.-Y.","family":"Yong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2024,11,20]]},"reference":[{"key":"S0031182024001252_ref42","volume-title":"Family Atractotrematidae Yamaguti, 1939","volume":"2","author":"Overstreet","year":"2005"},{"key":"S0031182024001252_ref29","doi-asserted-by":"publisher","DOI":"10.1017\/S0022149X17000906"},{"key":"S0031182024001252_ref38","doi-asserted-by":"publisher","DOI":"10.1007\/s11230-023-10093-5"},{"key":"S0031182024001252_ref18","doi-asserted-by":"publisher","DOI":"10.1007\/s11230-021-10002-8"},{"key":"S0031182024001252_ref22","doi-asserted-by":"publisher","DOI":"10.2307\/3277393"},{"key":"S0031182024001252_ref46","volume-title":"Molecular Cloning: A Laboratory Manual","author":"Sambrook","year":"2001"},{"key":"S0031182024001252_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpara.2021.08.004"},{"key":"S0031182024001252_ref44","doi-asserted-by":"publisher","DOI":"10.1016\/j.ympev.2008.03.024"},{"key":"S0031182024001252_ref28","doi-asserted-by":"publisher","DOI":"10.1007\/s00338-013-1043-z"},{"key":"S0031182024001252_ref32","doi-asserted-by":"publisher","DOI":"10.1093\/zoolinnean\/zlab002"},{"key":"S0031182024001252_ref15","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182022000282"},{"key":"S0031182024001252_ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s11230-014-9504-5"},{"key":"S0031182024001252_ref40","doi-asserted-by":"publisher","DOI":"10.1111\/jfb.15311"},{"key":"S0031182024001252_ref26","unstructured":"Fricke, R , Eschmeyer, WN and Van der Laan, R (eds) (2024) Eschmeyer's catalog of fishes: genera, species, references.
