Chalcosia thaivana [Zygaenidae Chalcosiinae]

[isidro]

This insect was seen for sale at a jewellry and fossil shop. Absolutely no data, but most of the butterflies seen here for sale are from south-east Asia species. The only label was the name that told Cyclosia imitans, but for me is evident that this is not Cyclosia imitans. Any ideas about the true ID?
Thanks!

after Endo & Kishida, Day-Flying Moth, 1999 it could be Chalcosia argentata or Chalcosia phalaenaria

Big thanks! You put me on the correct genus and after comparing images I'm almost sure that it's Chalcosia thaivana. Thanks!
