Vespericola was validly proposed on an introductory page (XVII) of volume 1, part 1 of Pilsbry's Land Mollusca of North America (1939). There the new genus-name was not printed attached to any associated species-name. Thus its gender was unspecified. Per the Code, in such cases the gender is to be treated as masculine. The fact that Pilsbry treated it as feminine in his full (1940) writeup is irrelevant.
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.
