Rodríguez et al elevated southern populations (Charina bottae umbratica) to species status and determined that C. b. utahensis isn't distinct from Charina bottae bottae. So Charina bottae now incompasses Charina bottae bottae and Charina bottae utahensis but not Charina bottae umbratica and there are no valid subspecies.

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.
