Trofimova et al. (2016) remarked as follows:
"Some authors treat the Asian dark form of abietis as a subspecies C. abietis argentata Bulter, 1881. Both forms are sympatric in the Central Siberia and further to Japan and Korea the dark form is transplaced by the European light form. Despite the geographical variability of external colour features, these forms have identical morphology of the male genitalia structure. Nine barcoded (COI 5' mDNA) specimens from Europe and European Russia as well as four dark form specimens show infra-secific barcode divergence of only 0.3% and therefore these forms are recognized here as only colour variations of C. abietis"

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.
