The main difference noted in the redescription was the presence of spines on the body. However, the lack of DNA data made confirming the true affiliation of this digenean challenging. New specimens sampled from <jats:italic>P. orbignyanus<\/jats:italic> allowed us to sequence the 28S, ITS, and COI genes. Fresh specimens were stained to compare their morphology with the holotype and voucher specimens. The digeneans found correspond with those reported from Mar Chiquita, described as <jats:italic>B. microacetabularis<\/jats:italic> (=<jats:italic>S. microacetabularis<\/jats:italic>). Genetic analyses clustered the newly sequenced individuals within the Cryptogonimidae, showing relationships with <jats:italic>Oligogonotylus manteri<\/jats:italic>, <jats:italic>Tabascotrema verai<\/jats:italic>, and <jats:italic>Caecincola parvulus<\/jats:italic> (28S); <jats:italic>T. verai<\/jats:italic>, <jats:italic>Lobosorchis<\/jats:italic> spp., <jats:italic>Euryakaina manilensis<\/jats:italic>, and <jats:italic>Metadena marina<\/jats:italic> (ITS); and <jats:italic>Siphoderina spp.<\/jats:italic> (COI). After comparing the species with cryptogonimids lacking spines in the oral sucker, a new genus, <jats:italic>Surianotrema<\/jats:italic> n. gen., is described. This genus increases the number of cryptogonimid genera known in South America to seven \u2013 three in freshwater and four in marine environments \u2013 with <jats:italic>Surianotrema<\/jats:italic> n. gen. being the first to be sequenced. New sequences from other South American cryptogonimids are necessary to better understand the phylogenetic relationships between genera within this family, particularly in South America.<\/jats:p>","DOI":"10.1017\/s0022149x25000239","type":"journal-article","created":{"date-parts":[[2025,3,10]],"date-time":"2025-03-10T13:03:41Z","timestamp":1741611821000},"source":"Crossref","is-referenced-by-count":2,"title":["The history continues: From <i>Steringotrema microacetabularis<\/i> (Fellodistomidae) to <i>Bacciger microacetabularis<\/i> (Baccigeridae) genetic evidence reveals a new genus of Cryptogonimidae"],"prefix":"10.1017","volume":"99","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7177-333X","authenticated-orcid":false,"given":"M.M.","family":"Montes","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8451-6906","authenticated-orcid":false,"given":"J.","family":"Barneche","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-8211-4135","authenticated-orcid":false,"given":"T.","family":"Acu\u00f1a Gonzalez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2676-3172","authenticated-orcid":false,"given":"G.","family":"Cavallo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8612-3057","authenticated-orcid":false,"given":"M.","family":"Iba\u00f1ez Shimabukuro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1728-9296","authenticated-orcid":false,"given":"M.","family":"Moncada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5375-9155","authenticated-orcid":false,"given":"S.R.","family":"Martorelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,3,10]]},"reference":[{"key":"S0022149X25000239_r10","volume-title":"Manual de peixes marinhos do sudeste do Brasil (Handbook of marine fish in southeastern Brazil)","author":"Figueiredo","year":"2000"},{"key":"S0022149X25000239_r1","doi-asserted-by":"publisher","DOI":"10.2478\/s11686-008-0055-2"},{"key":"S0022149X25000239_r2","doi-asserted-by":"publisher","DOI":"10.1016\/0020-7519(93)90106-9"},{"key":"S0022149X25000239_r18","doi-asserted-by":"publisher","DOI":"10.22370\/rbmo.2019.54.3.2015"},{"key":"S0022149X25000239_r9","doi-asserted-by":"publisher","DOI":"10.1023\/A:1006248418404"},{"key":"S0022149X25000239_r19","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7519(03)00049-3"},{"key":"S0022149X25000239_r15","doi-asserted-by":"publisher","DOI":"10.1006\/mpev.2000.0802"},{"key":"S0022149X25000239_r20","doi-asserted-by":"publisher","DOI":"10.1093\/sysbio\/sys029"},{"key":"S0022149X25000239_r3","doi-asserted-by":"publisher","DOI":"10.1139\/f03-071"},{"key":"S0022149X25000239_r24","doi-asserted-by":"publisher","DOI":"10.1023\/A:1025546001611"},{"key":"S0022149X25000239_r25","doi-asserted-by":"publisher","DOI":"10.1111\/1755-0998.12358"},{"key":"S0022149X25000239_r6","first-page":"261","volume-title":"Keys to the Trematoda","volume":"2","author":"Bray","year":"2008a"},{"key":"S0022149X25000239_r21","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth.2089"},{"key":"S0022149X25000239_r4","first-page":"559","volume-title":"Baldisserotto B and Gomes LC (eds), Esp\u00e9cies nativas para piscicultura no Brasil, segunda ed","author":"Bianchini","year":"2010"},{"key":"S0022149X25000239_r8","doi-asserted-by":"publisher","DOI":"10.1007\/s10750-005-5446-x"},{"key":"S0022149X25000239_r14","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2148-14-82"},{"key":"S0022149X25000239_r5","doi-asserted-by":"publisher","DOI":"10.1016\/0001-706X(93)90079-Q"},{"key":"S0022149X25000239_r11","doi-asserted-by":"publisher","DOI":"10.1023\/A:1006113721899"},{"key":"S0022149X25000239_r16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jembe.2016.08.008"},{"key":"S0022149X25000239_r13","doi-asserted-by":"publisher","DOI":"10.1093\/bib\/bbx108"},{"key":"S0022149X25000239_r22","doi-asserted-by":"publisher","DOI":"10.1214\/aos\/1176344136"},{"key":"S0022149X25000239_r23","first-page":"195","article-title":"Estudios parasitol\u00f3gicos en la albufera de Mar Chiquita, Provincia de Buenos Aires, Rep\u00fablica Argentina","volume":"29","author":"Suriano","year":"1983","journal-title":"I.
