We examined the morphological variation of the cyst and motile stage by incubation experiments from sediment samples collected in coastal British Columbia (Canada), and compared it to closely related species. The theca of <i>A. saanichi</i> is differentiated from related species by overall size, the asymmetry of the intercalary plates and the right-sulcal plate (S.d.) not touching the cingulum. We provide a key to differentiate all closely related species. <i>A. saanichi</i> can be readily distinguished from <i>A. minutum</i> by a distinctively large cyst with a broad 2a type archeopyle and regularly spaced processes with relatively broad bases and aculeate process tips. Molecular phylogenetic analyses of large and small subunit (LSU and SSU) rDNA sequences demonstrated a close affinity of this species to <i>A. minutum</i>; however, the relatively high level of sequence conservation in dinoflagellate rDNA sequences made these particular markers inadequate for distinguishing one species from the other. Sediment-trap data suggest that <i>A. saanichi</i> has a preference for cooler temperatures and lowered salinities.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>Archaeperidinium saanichi</i> sp nov.: a new species based on morphological variation of cyst and theca within the <i>Archaeperidinium minutum</i> Jörgensen 1912 species complex","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Dinoflagellate; Saanich Inlet; LSU rDNA; Single-cell PCR; Spiny browncyst; SSU rDNA","OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2015-10-30","DateCreate":"2013-12-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000311264100005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.marmicro.2012.08.002"},"refs":null,"anarec":{"AnaID":231650,"PubliDate":2012,"Pagination":"48-62","XtraPublOfAnaID":null,"ISBN":null,"Volume":"96-97","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43516,"SerRR":"Marine Micropaleontology.
