Pelham catalogue accepted the transfer of mexicanus and octomaculata to Ectomis from Polythrix, following suggestions presented in Li et al. (2019). This swap keeps things consistent with that decision in regards to taxa not covered by the Pelham catalogue but also transferred to Ectomis in Li et al.
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.
