Nomenclature Ochetostomum gaertneri was named as a replacement name for Lumbricus thalassema and Thalassema neptuni of Pallas (1774) and Cuvier (1830). Kajihara (2019) relied on Article 11.6 of the Code (ICZN 1999) to invalidate similar such replacement names created in Diesing's 1850 publication. That article is not relevant as it applies to names mentioned in synonymies. The situation is simply that one taxonomist can legitimately change a genus assigment (that is subjective taxonomy), but must have a reason based on a violation of nomenclatural rules to create a new replacement name for the species name already in the literature (that is nomenclature). Adoption of unnecessary replacement names as invented in Diesing's works would result in anarchic confusion, and they can be ignored as invalid, although they may be available names. [details]
