Leighton's Sand Snake (Psammophis leightoni). Three species of sand snake - the Cape Sand Snake (Psammophis leightoni), the Namib Sand Snake (Psammophis namibensis) and the Fork-marked Sand Snake (Psammophis trinasalis) were recently synonymized and are now treated as a single species.
Apologies and thanks for catching that. I reverted Psammophis trinasalis -> Psammophis afroccidentalis, changed it to Psammophis trinasalis -> Psammophis leightoni (see above) and committed. Thanks all!
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.
Psammophis trinasalis is now Psammophis leightoni
