Taxonomy

source of synonymy Knight-Jones, Phyllis. (1984). A new species of Protoleodora (Spirorbidae: Polychaeta) from eastern U.S.S.R., with a brief revision of related genera. Zoological Journal of the Linnean Society, London. 80(2-3): 109-120., available online at https://academic.oup.com/zoolinnean/article-abstract/80/2-3/109/2703213
note: Dexiospira is a homonym and Knight-Jones replaces it with its synonym Neodexiospira [details]

page(s): 148-150; note: Fauchald's 1977 guide has Dexiospira as valid, Neodexiospira as its synonym. This evidently precedes knowledge that the spirorbin Dexiospira genus is a homonym, which is replaced by Neodexiospira [details]
