The date of publication of the species is that of the original
combination if it otherwise is validly published. 

If the new combination makes the transferred species a junior homonym of
an older species in the new genus, then the younger species (the one
just transferred) would need a new name and would take date and
authorship from the new name. 

Have I understood you correctly?

Subject: priority

I have a question concerning publication date and priority.  If a
species is originally described in one genus and is later transferred to
another genus, is the date of publication of that particular
name/combination considered to be the date of the original publication
or the date of the transfer?  My problem arises when trying to establish
priority when a second species with the same epithet was described in
the second genus after the original publication of the first species but
before the transfer.

Which name is valid and which becomes the junior synonym?  I've looked
in the ICZN, but was unable to find the answer.
