"It should be Helicostyla smaragdina (Reeve, 1842). H. smargadina is a wrong name, which has spread through some databases. EOL provides both names, Wikipedia too. It is a snail green. Smaragdina means similar to emerald. Smargadina not mean anything."
I have found a few 1800s Philippine snail catalogues including this species. It is listed under a variety of latin endings and credited discoverers, but the base is consistently "smarag" instead of "smarga."
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.
