We use type and other material derived from both the National Water Quality Assessment (NAWQA) program in the USA and from Egypt to assess five different taxa, two of which are described as new to science (<i>Nitzschia lowei</i>, sp. nov., <i>Nitzschia potapovae</i>, sp. nov.) and another is made as a new nomenclatural combination (<i>Nitzschia kurzeana</i> var. <i>multistriata</i> (Hohn) comb. nov.). Other names used in the literature for some of these taxa are considered and discussed. Based on the features of sigmoid valves, eccentric raphe not in an elevated keel, lack of a conopeum, strongly bent, elongated external proximal raphe ends extending onto the valve face, and presence of a differentiated central 'nodule', members of this group are clearly differentiated from the generitype of <i>Nitzschia</i> and most other recognized sections of the genus.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Taxonomy and nomenclature of some members within the Obtusae section of <i>Nitzschia</i> Hassall (Bacillariophyceae) including descriptions 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":"light microscopy, new species, new combination, Nitzschia, nomenclature, scanning electron microscopy, Section Obtusae, taxonomy","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-12-16","DateCreate":"2021-12-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000707492300011","VABBcode":null,"OpenAcc":1,"DOI":"10.5507/fot.2021.010"},"refs":null,"anarec":{"AnaID":348298,"PubliDate":2021,"Pagination":"247-258","XtraPublOfAnaID":null,"ISBN":null,"Volume":"21","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":229174,"SerRR":"Fottea.
