The prevalence of infection was 39.6% (36 infected fish\/ 91 examined). Morphologically, the nematodes lacked a ventral sucker, and the number of caudal papillae in males identifies them as members of the nominotypical subgenus Dichelyne of the genus Dichelyne. The new species differs from its congeners by the presence of a conical, spiny appendage at the tip of the tail and in the number and distribution of its 10 pairs of caudal papillae: six pre-cloacal, one adcloacal, and three post-cloacal. This new species represents the fourth record of the genus in Brazilian territory and the first record for estuarine waters in northern Brazil, with Propimelodus eigenmanni registered as a new host for the genus.<\/jats:p>","DOI":"10.1590\/s1984-29612026020","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T11:01:37Z","timestamp":1783335697000},"source":"Crossref","is-referenced-by-count":0,"title":["A new species of Dichelyne (Nematoda: Cucullanidae) parasitizing fish of the family Pimelodidae in the Amazon estuary, northern Brazilian coast"],"prefix":"10.1590","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3860-7173","authenticated-orcid":false,"given":"Gabrielly Pantoja","family":"Alves","sequence":"first","affiliation":[{"name":"Universidade Federal Rural da Amaz\u00f4nia,  Brasil; Universidade Federal Rural da Amaz\u00f4nia,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6219-1437","authenticated-orcid":false,"given":"Ricardo Luis Sousa","family":"Santana","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural da Amaz\u00f4nia,  Brasil; Universidade Federal Rural da Amaz\u00f4nia,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6078-8341","authenticated-orcid":false,"given":"Luis Augusto Ara\u00fajo dos Santos","family":"Ruffeil","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural da Amaz\u00f4nia,  Brasil; Escola Estadual de Ensino T\u00e9cnico do Par\u00e1 Dr. Celso Malcher,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7833-1334","authenticated-orcid":false,"given":"Elane Guerreiro","family":"Giese","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural da Amaz\u00f4nia,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3221-5017","authenticated-orcid":false,"given":"Raul Henrique da Silva","family":"Pinheiro","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural da Amaz\u00f4nia,  Brasil; Universidade Federal Rural da Amaz\u00f4nia,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2026]]},"reference":[{"issue":"4","key":"ref1","doi-asserted-by":"crossref","DOI":"10.1590\/0001-3765201920190544","article-title":"First record of Dichelyne (Dichelyne) bonacii (Nematoda, Cucullanidae) parasiting the intestine of two species of lutjanid fish (Perciformes, Lutjanidae) on the northeast Brazilian coast","volume":"91","author":"Alves AM","year":"2019","journal-title":"An Acad Bras Ci\u00eanc"},{"key":"ref2","series-title":"CIH Keys to the nematode parasites of vertebrates: Archival Volume.","author":"Anderson RC","year":"2009"},{"key":"ref3","series-title":"Atlas do estu\u00e1rio amaz\u00f4nico.","author":"Barthem R","year":"2024"},{"issue":"4","key":"ref4","first-page":"215","article-title":"Cucullanus mexicanus sp. n.
