[Taxacom] Taxonomic concepts [Was: Questions on Taxonomic Code of Practice]

In zoology, Aus bus (L. 1758) non XYZ (2013) would more often imply homonymy, not misidentification, i.e. Aus bus (L. 1758) and Aus bus XYZ (2013) are distinct available names (homonyms).

So, we have 3 separate issues, viz. (1) misidentifications; (2) homonymy; and (3) "taxonomic concepts". Of these, (3) doesn't really get explicitly discussed in zoological taxonomy very much at all (at most, sensu lato and sensu stricto get used to distinguish between broader and narrower concepts).
There isn't a standard terminology to deal unambiguously with (1) , (2) or (3), so there is much potential for confusion!

No it doesn't. It means 'in the sense of' or 'as used by'. If it implies anything at all, it is one of difference of interpretation or understanding. If there was a misidentification or similar stuff-up involved, we would/should be more explicit. 'Non' and 'not' have been used for this sort of thing.

Which is what 'sensu' means...

But as these are taxonomic assertions, none of 'The Codes', being nomenclatural and all, really need to bother themselves with all this. ;)
