The case seems a bit complicated:
The name was "validly" introduced, i.e. according to the ICZN regulations.
Moreover, the specific epiteth "lucifer" seems to have page priority over
"gigas". That would mean strictly applying the ICZN code, would make gigas
a junior synonym of lucifer.
However, as gigas is an extremely well established name, the name lucifer
ought to be suppressed by the ICZN. I reckon that if someone would petition
the ICZN, that they would rule is such a way.
