This name was mentioned in a Request for an Opinion. Rule 8 of the 2022 revision of the ICNP does not require that the name of a class validly published before 1 January 2012 be formed from the stem of the name of the type genus of the type order of the class plus the ending ia. This class name is orthographically correct (nominative plural noun, not formed from the name of the nomenclatural type).Publication:
