Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Discidae. This
happens when we can't automatically assign an identification to one of the
output taxa.
Review identifications of Discus 87994
D. rotundatus and D. perspectivus have been moved to Gonyodiscus, leaving D. ruderatus as the sole European member of Discus s.s. D. rotundatus has been introduced to a variety of places around the world, particularly in North America. This split bumps genus IDs of Discus s.l. to family in areas where G. rotundatus overlaps with Discus s.s.

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.
