Why was Achromobacter xerosis removed from the NCBI taxonomy?
For whatever it's worth, I queried NCBI support about this and got a reply:

  Subject: Reason for removal of a species from the taxonomy?
  
  Hi,
  
  I notice that the species Achromobacter xerosis used to be listed in the NCBI taxonomy at https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=216898 but no longer is. I haven't been able to track down any documentation hinting at why a species would ever be removed from the taxonomy. Is there any such documentation that I've missed, and are you able to explain why this species in particular was removed?
  
  Thanks in advance for your time,
  Mark

  Dear Mark Amery:
  The NCBI Taxonomy database records exist to support data that are in other NCBI databases. A review of the Taxonomy database must have identified that we have no records for which Achromobacter xerosis
  is designated as the organism name.
