Apparently a junior homonym to Anthostoma Rafinesque,1815 in Platyhelminthes, but that name was a replacement for Chariophyllus Bloch, 1782, an unavailable name, as the work by Bloch was not consistently binominal. It is somewhat debatable if an unavailable name can be simply replaced as such. However, while Pettibone (1957) noted it was pre-occupied by the Rafinesque usage, Anthostoma Schmarda, 1861 is in any case junior to Naineris Blainville, 1828, as Pettibone would have also considered. Pettibone included Anthostoma in the synonymy of her new Naineris subgenus, Polynaineris, currently disused (Blake 2017)
