what becomes of "kleptotypes" if the holotype is de stroyed?

types (holotypes, lectotypes or neotypes) have nothing to do with
identification - they cannot be replaced just because they are unusable in
taxonomy. If the designated holotype is lost another cannot be 'found' - it
has to replaced by a lectotype or a neotype. If it is not lost it can only
be supplemented by an epitype (ICBN; not sure about ICZN).

As long as the material is usable for identification then it is the
holotype (since it was a fragment of the original hootype). Otherwise
holotype is lost and another one needs to be found/ designated. I don't
much confusion in this other than determining if the remaining material
any use or not. Unfortunately this situation happens all too often,
frequently in circumstances similar to the example provided by Ms
so this question is of general interest.
