For branches under taxon frameworks like references (like Reptiles referencing Reptile Database) unless they are deviations the source will always be the reference. Good catch about the source, but I think the easiest way to find the source/reference is to click on the Green Match link above
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.
The noted source for this taxon swap links to the wrong RepDB page. The link should be: https://reptile-database.reptarium.cz/species?genus=Virginia&species=striatula
Or a link to the paper behind the justification to move this species back to Virginia: https://doi.org/10.1016/j.ympev.2023.107844
