Superseded combination

In taxonomy, a superseded combination is a notice of change to the binomial nomenclature of the accepted name of a species.

[4] If the species is moved again to a third genus, both of the older names are considered superseded combinations.

[4] If the species were moved back to a previous genus, the International Commission on Zoological Nomenclature would not consider the current name to be a new combination.

For example, in 1766 Peter Simon Pallas described a new species of marine polychaete worm he called Aphrodita flava.

[8] In 1867, that name became a superseded (original) combination when Hjalmar Kinberg moved the species to Thesmia, creating the new combination Thesmia flava.
