Unfortunately, that too is a mess. In a way, anybody can attempt to "add" a new species by describing it in a paper. So you'd typically send your specimen to the most fitting specialist willing and able to write that paper. The paper would then hopefully be reviewed by a naming authority. But a naming authority is just a bunch of people that got this authority by reputation. It's not the government. There may be regional authorities as well as multiple naming authorities for the same groups of species, not agreeing on species' status. All of this mess is then stitched together into a best-effort central database. Not even the categorization (so taxonomy levels) is singular, there's multiple systems. Species are constantly moved, split, merged.
