Owada & Kobayashi, in the Thyrididae chapter of Moths of Laos treated several Picrostomastis and Hypolamprus species, with a lengthy note under Hypolamprus grisea, comparing the genitalia of the type species for each genus. P. leucoschista (the type species of Picrostomastis) differs substantially from "P. subrosealis" and thus Owada & Kobayashi returned subrosealis to Hypolamprus
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.
