There are a lot of evidence (molecular, ecological, ethological, geographical) that support the existence of B. variegata pachypus as a distinct and valid subspecies in B. variegata group. So I think is better consider "Bombina pachypus - 24500" as a fully synonym only of B. variegata pachypus and then replace it with "Bombina variegata pachypus - 479255" and not with "Bombina variegata - 24496"
Also in Pabijan, Wandycz, Hofman, Węcek, Piwczyński, and Szymura (2013), B. variegata pachypus is considered a diffent allopatric lineage in the Bombina variegata group ("In the western Palearctic, the Late Pliocene to Pleistocene climatic vagaries most probably induced vicariant events in the evolutionary history of B. variegata that led to the formation of the two Balkan B. v. scabra lineages and the allopatric B. v. pachypus in the Apennine Peninsula.")
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.
