Liston et al. 2022: ..."Very regrettably, we now have to accept that the valid name for Abia nitens auct. is Abia brevicornis Leach, 1817, and the valid name for what has recently been called Abia sericea is A. nitens. The taxonomic and nomenclatural changes, summarized:"
Abia brevicornis Leach, 1817
= Abia nitens auct. nec Linnaeus. Misidentification of Tenthredo nitens by, for example: Dalla Torre (1894), Konow (1905), Taeger (1998), Liston and Späth (2006).
Abia nitens (Linnaeus, 1758)
= Abia sericea: Dalla Torre (1894), Konow (1905), Enslin (1917), Liston and Späth (2006), Taeger et al. (2010).
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.
