A nomen oblitum (Latin for "forgotten name") is a technical term, used in zoology. In its present meaning it came into being with the fourth, 1999, edition of the International Code of Zoological Nomenclature. In the first and second editions of the zoological Code (valid between November 6, 1961 and January 1, 1973) the term was also used, but names then indicated as such do not have the same status. A notable example of this previous use is that of Scrotum humanum.
