Then it seems cut and dry. But dont use POWO as the authority in making the decision. Although for European species one would think that they would be more comprehensive.
thanks.
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
Beware: POWO is not up to date on infraspecifics!! Do not use POWO as an authority on infraspecifics! You will need to go to source.
