This is an error tracking category for {{Taxonbar}} templates which have manual ID values differing from Wikidata. This may or may not be an error.

For example, in the case of Aaadonta angaurana, {{Taxonbar|iucn=4}} would be an error, and it would be placed into this category. The correct value is |iucn=3, and, since the correct value already exists on Wikidata, |iucn= should be removed from the template.

In the case of Penstemon barrettiae, {{Taxonbar|eol=1701233}} would not be an error, since 1701233 redirects to 578247 at eol.org, and it would still be placed into this category. Wikidata should then be checked to use 578247, the preferred value, and |eol=1701233 then removed from the template.

Pages in this category should only be added by Module:Taxonbar.
