Several of the studied taxa, originally considered as varieties of <i>N. sigma</i>, showed sufficient morphological differences to be raised to species level or be described as new species, due to nomenclatorial issues. <i>Nitzschia rigidula</i> (Grunow) stat. nov., a freshwater species, originally described as <i>N. sigma</i> var. <i>rigidula</i> from the region around Brussels (Belgium) is the smallest of the new taxa. Analysis of another, former <i>N. sigma</i>-variety, proved to be based on an illegitimate, superfluous Kützing taxon, showed that two independent species were included under the same name, <i>N. sigma</i> var. <i>rigida</i>, that are described in this paper as two new, brackish to freshwater species: <i>Nitzschia neorigida</i> sp. nov. and <i>N. pararigida</i> sp. nov. All species are morphologically characterised and illustrated and their ecological preferences based on the associated diatom flora in the samples, are better defined.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Revision of the <i>Nitzschia sigma</i> complex (Bacillariophyta), a frequent cosmopolitan species in disguise with the description of two new species","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Morphology; new species; Nitzschia; type material","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-02-23","DateCreate":"2023-02-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000898610700001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/23818107.2022.2156601"},"refs":null,"anarec":{"AnaID":361355,"PubliDate":2023,"Pagination":"15","XtraPublOfAnaID":null,"ISBN":null,"Volume":"Latest Articles","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":290652,"SerRR":"Botany Letters.
