 is split off, from another taxon. This other taxon will be better known, usually bigger, and will continue to exist, even after the segregate taxon has been split off. A segregate will be either new or ephemeral: there is a tendency for taxonomists to disagree on segregates, and later workers often reunite a segregate with the 'mother' taxon.

If a segregate is generally accepted as a 'good' taxon it ceases to be a segregate.

If a segregate is generally accepted as a 'good' taxon it ceases to be a segregate. Thus, this is a way of indicating change in the taxonomic status. It should not be confused with, for example, the subdivision of a genus into subgenera
Subgenus

In biology, a subgenus is a taxonomic rank directly below genus. See rank and rank .In ICZN, a subgeneric name can be used independently or included in a binomen, in parentheses, placed between the name of a biological genus and specific name: e.g....
