Duplicate taxon pages for the same species. Following priority for gender agreement per ICZN (from genus transition). The majority of sources semi-followed by iNat for insect taxa support that Genia requires the -us ending and not -a ending for species.
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.
Agree with the change, but not the reasoning behind it. Please have a look at this article: https://doi.org/10.3897/nl.42.34187
