Preferred term

distagmonym

Nomen that has not had a universal or significant use in non-systematic literature after 31 December 1899, being an aphonym, eneonym, schizoeurydiaphonym or stenodiaphonym. Roy 2002: Amnesonym (see the Code definition). (Dubois 2005a)

amnesonym
nomen oblitum

Etymology: G: δισταγμός (distagmos), doubt, uncertainty - ὄνομα (onoma), name.

Code: Nomen oblitum (Definition by Hawksworth 2010): Applied after 1 January 2000 to a name, unused since 1899, which as a result of an action taken under the Code does not take precedence over a younger synonym or homonym in prevailing usage; the younger name that takes precedence over the nomen oblitum may be called a nomen protectum; the term nomen oblitum was also applied to a disused senior synonym rejected between 6 November 1961 and 1 January 1973 under the Code editions then in force; nomina oblita remain available names unless a junior synonym has been used more than a specified number of times in the immediately preceding 50 years (i.e. 25 works published by at least 10 authors and encompassing a span of not less than 10 years).
