I object to the insertion of "[ earlier ]"! It only confuses the matter.
Just as with children, a younger species is not one created BEFORE
(earlier than) an older one, but LATER than it

The date of publication of the species is that of the original
combination if it otherwise is validly published.  [RG: This is because
that
date is always attached to the species name regardless of the generic
name
it was originally combined with.  It is valid even if the original genus
itself is invalid (as long as the other requirements of publication were
originally met.) The date is the date the introduction of  the species
level
epithet came into availablilty.]

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

**********

When a junior homonym is created by this kind of taxonomic treatment,
the
FIRST course of action is to see if the junior homonym has synonyms.  If
so,
the oldest available synonym of the transferred species name becomes the
species name.  See 60.2
