There is a clear genetic separation between the population on North Brother Island and two other groups (western Cook Strait islands and all northern populations) on the basis of both allozyme genetic and morphometric variation (DAUGHERTY et al. 1990). However, the split does not seem to be as deep as initially thought and as a consequence, HAY et al. (2010) recommended to treat all tuataras as a single species, i.e. synonymize guntheri with punctatus.
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.
