Confused about this O.croesus lydius

[trehopr1]

I noticed today that there is a Russian seller on EBay touting a supposed new "form" of O.croesus lydius. It is being called form fastidiosus from Halmahera Island. He even notes it as being a Holotype!!
Firstly, are Holotype's even designated for forms OR even subspecies?? Never heard of that. Only for new SPECIES or so I thought.
Could it be called properly some other "type"...

I didn't think any new forms or subspecies of Ornithoptera were still being named since these butterflies as a group have been way "over-studied" and some of the already named forms or subspecies still remain questionable or even dubious !

To make things even more ridiculous is the fact the seller is asking $1000 USD for the specimen.

Would someone kindly clarify this rather confused situation for me. I just like to keep abreast of the ever changing scientific environment within Entomology.

P.S.   Or at least I would like have a better working knowledge for some of the "phony baloney" out there which is always evolving !

there are no holotypes at all of forms.

There are, however, holotypes of subspecies.

My general rule is to consider any new "subspecies", let alone forms, of any Ornithoptera as synonyms unless presented with very good evidence to the contrary.

A collector-friend in another state taught me my current philosophy regarding validity of doubtful taxons:
If I lack specimens, the name is probably a synonym anyway. But if I've managed to acquire one or more, the name is
definitely valid!
