The reference to synonimise lemniscata with linea is ??? It definitely is not in the JJ de Freina reference used by Afromoths (which only deals with the genus Amata).
Anyway, the sinking into linea is accepted by Afromoths, so I'm going to swap it here. This taxonomy may change in future...
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.
