Two novel species of gregarines were discovered in polychaete hosts collected in Canada and Japan. The trophozoites of <i>Trichotokara japonica</i> n. sp. were oval to rhomboidal shaped, and covered with longitudinal epicytic folds with a density of six to eight folds/micron. The nucleus was situated in the middle of the cell, and the mucron was elongated and covered with hair-like projections; antler-like projections also extended from the anterior tip of the mucron. The distinctively large trophozoites of <i>Trichotokara eunicae</i> n. sp. lacked an elongated mucron and had a tadpole-like cell shape consisting of a bulbous anterior region and a tapered tail-like posterior region. The cell surface was covered with longitudinal epicytic folds with a density of three to five folds/micron. Small subunit (SSU) rDNA sequences of both species were very divergent and formed a strongly supported clade with the recently described species <i>Trichotokara nothriae</i> and an environmental sequence (AB275074). This phylogenetic context combined with the morphological features of <i>T. eunicae</i> n. sp. required us to amend the description for <i>Trichotokara</i>. The sister clade to the <i>Trichotokara</i> clade consisted of environmental sequences and <i>Lecudina polymorpha</i>, which also possesses densely packed epicyctic folds (3–5 folds/micron) and a prominently elongated mucron. This improved morphological and molecular phylogenetic context justified the establishment of <i>Paralecudina</i> (ex. <i>Lecudina</i>) <i>polymorpha</i> n. gen. et comb.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Discovery of a diverse clade of gregarine apicomplexans (Apicomplexa: Eugregarinorida) from Pacific eunicid and onuphid polychaetes, including descriptions of <i>Paralecudina</i> n. gen., <i>Trichotokara japonica</i> n. sp., and <i>T. eunicae</i> n. sp.","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:33:00.301179","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Eugregarines; parasite; phylogeny; taxonomy","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-08-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000315643300002","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/jeu.12015"},"refs":null,"anarec":{"AnaID":288118,"PubliDate":2013,"Pagination":"121-136","XtraPublOfAnaID":null,"ISBN":null,"Volume":"60","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43225,"SerRR":"Journal of Eukaryotic Microbiology.
