Dear John,

Totally agreed.
Some journals require this information - vouchers for each presented DNA sequence, but several and important journals do not.

Assunto: ***SPAM*** [Taxacom] cautionary tale on molecular vouchers

I would expect that nowadays all molecular studies deposit voucher specimens that allow for subsequent verification. The importance of this procedure was recently highlighted for me in a molecular study of some moths where the results linked a species of one genus to species of a very different genus (the two genera are otherwise extremely distinct in every way). So naturally I investigated the voucher for that specimen which was said to have been deposited in a collection. It turns out that, so far, this appears not to have been the case with nothing in the pinned collection and frozen material for the study had since been thrown out. So, one is left with a insoluble situation (not even any photos of the specimens). Mistakes happen, and I am as guilty of that as anyone, so no criticism directed at the authors. Just a lesson in the importance of actually depositing the vouchers cited in publication.
