These are pseudo-homonyms, as they are governed by different 
Nomenclatural Codes. There is no conflict.

I may be reading between the lines, but it sounds like you may 
believe that there is such a thing as "page priority". There is not, 
at least not in the Zoological Code. The first reviser chooses which 
of two (or more) simultaneously-published names is to be used as 
valid, and they are - and always have been - free to choose the name 
that appears last. "Page priority" is one of the most prevalent 
"urban legends" surrounding the Code. I doubt it is any different for
