Dear Steve,
        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
Article 56.

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
identifiable.  The name will then be fixed to the species that the epitype
belongs to.
        The epitype is new in the Tokyo Code; it is defined in Article
9.7.  An epitype is designated in the same manner as any other type,
subject to the conditions mentioned in Art. 9.7.
