"Type species of three poorly known Arctiinae genera, Paraplastis Hampson, 1901, Migoplastis Felder, 1868 and Dondera Moore, 1877 are examined. All three taxa are transferred here from the subtribe Arctiina to the subtribe Nyctemerina of the tribe Arctiini. Paraplastis and Migoplastis (= Pachyphilonia Butler) are synonymized with the subgenus Deilemera Hübner, [1820] of the genus Nyctemera Hübner, [1820]"

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.
