I think you have two options under the Tokyo Code:
1. Names may still be rejected, but it is no longer an informal process.
You must propose the name for addition to the list of rejected names, and
it will be reviewed by committee. The procedure for this is given in
2. The inadequate holotype may be supported by designating an epitype.
This is a supplemental type specimen, to be used to clarify the
application of a name when the original material is unidentifiable for any
reason. The epitype must be consistent with the characters of the
holotype, so far as can be determined, and of course it should be clearly
