[Taxacom] oldest species name priority

[John Grehan]

Dear colleagues,

I would be grateful for comment regarding use of names where normally the
oldest validly published name takes priority. But do the rules of
nomenclature allow for acceptance of a later name where it has been widely
used over a long period of time if an application is made to that effect? I
recall that this can be done, but would be grateful for clarification.
