I suspect that this name was never validly published, but only in a PhD. It has never been properly used in South Africa.
Worms however recognizes it:

It is sunk in Brahms (which is the likely source of the name as many of Koekemoer's unpulbished genera were accommodated in the PRECIS database "prepublication" as it was an inhouse PhD):

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.
