Assuming the name is "repeated", this is the protologue, with basionym. In
the unlikely even that the diagnosis referred to the name only by
bibliographic citation, without repeating it, the diagnosis is of no
meaning wrt the Code.

If there were no diagnosis accompanying the name, but only a bibliographic
reference to one (and the name were new), I suspect this would be a nomen
nudum according to the ICBN, but I'm no Code Warrior.
