Thank you very much, John and Steve!
It indeed seems that the description of Punctacteon cebuanus was one more 
useless description...

Subject: Re: [CONCH-L] Punctacteon question

anecdotally I think i have seen some dealers call them synonyms, but i
can't find anything to back that up. Here is a cut and paste from the
relevant index of Philippine Marine Molluscs, a reference i do not
own, Richard Willan and Sheila Tagaro are the authors, along with
Guido Poppe.

It looks like 'variegatus' does not appear in the index? that could be
relevant if true.
