This is not a Merge or a Split - it is a 2-to-2 relationship that can't be fully represented here. A second output should be Pantherophis ramspotti A recent paper by Crother et al. takes 2 concepts Pantherophis vulpinus & Pantherophis gloydi, redefines the boundary separating them producing two other concepts Pantherophis ramspotti & Pantherophis vulpinus (http://www.hindawi.com/isrn/zoology/2011/436049/)

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.
