From editor or global species database
Type species The type species of Neodexiospira is Spirorbis formosus Bush, 1905 accepted as Neodexiospira formosa (Bush, 1905) by original designation by Pillai (1970: 143). Spirorbis pseudocorrugatus Bush, 1905, the type species of Dexiospira as designated subsequently by Chamberlin (1919: 478), is NOT also the type species of Neodexiospira. The statement that it was the type species of Neodexiospira was a lapsus made by Knight-Jones, 1984. Unfortunately subsequent authors, including recently Kupriyanova, Rzhavsky & ten Hove, 2019 in a review, have repeated this lapsus without questioning it. [details]

Status Pillai (1970: 143) named Spirorbis formosus Bush, 1905 from Bermuda as type species of his new genus Neodexiospira. Knight-Jones (1972: 5) considered the genus to be an invalid synonym of Dexiospira Caullery and Mesnil 1897, which she treated as a valid subgenus of Janua Saint-Joseph 1894. Later Knight-Jones (1984:110) reported that Dexiospira was a junior homonym and replaced it with junior synonym Neodexiospira Pillai, 1970. She also states the type species of Neodexiospira is N. pseudocorrugata (Bush, 1905) (the type of Dexiospira). Neodexiospira pseudocorrugata is definitely not the type of Neodexiospira, but unfortunately the statement has been adopted by several others, continuing up to 2023 when corrected by WoRMS editors. Neodexiospira is not a replacement name, instead the situation is a synonymy and obviously any synonym retains its original type species. If it did not then there would be chaos in nomenclatural stability. [G. Read, September 2023] [details]

Grammatical gender Neodexiospira should be feminine as most 'spira' genus names are treated as feminine with their adjectival species names being given feminine suffices. [details]Status Pillai (1970: 143) named Spirorbis formosus Bush, 1905 from Bermuda as type species of his new genus Neodexiospira.
