[Taxacom] Does the species name have to change when it moves genus?

"The man has admitted he not only has a tea habit, but is also into divination. A lost cause."
OK, a bit of hyperbole on my part. The kind of thing I had in mind was a biologist saying "I made these observations on species x (citing paper on that species)" with no other evidence (e.g., a specimen, a sequence, a determination by a taxonomist). If I have something more concrete (e.g., a voucher) then, for example, I could say "I've sequenced this specimen and it's not that species at all", or "a specialist in the group has subsequently published on that specimen and it's a different species." Plenty of scope for a taxonomist to eyeball the specimen and say "that's obviously Aus xus".
I regard taxonomic names as essentially tags on sets of things (e.g., specimens, observations), and given the rate at which observations are being generated we will have lots of data not attached not to a name but to a specimen. Thats where I was going with this.
I wasn't dismissing what taxonomists do as merely issuing "vague assertions." I spent a couple of years as an undergraduate and Masters student obsessing over whether New Zealand had just one species of peacrab, or whether the populations found in horse mussels were a second, new species. Allozyme electrophoresis, morphometrics, larval development, plankton sampling, comparative parasitology, type specimens from Paris - yep, two species. I get that this requires work.

The man has admitted he not only has a tea habit, but is also into divination. A lost cause.
