Schmidt & McGuinness in Pohl & Nanz 2023 treat the nearctic genera Nasusina and Prorella as synonyms of Eupithecia, based on morphological and molecular characters. These changes have been adopted by Moth Photographers Group, which BugGuide follows.
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.
@hughmcguinness @joannerusso Does this taxon change look correct, and are there any related ones to also make?
