Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Automolus. This

Western Woodhaunter Automolus virgatus is split from Eastern (formerly Striped) Woodhaunter A. subulatus (Clements 2007:280)
Summary: The Western Woodhaunter of Central America and northwestern South America is now considered a distinct species from the Eastern Woodhaunter of the western and central Amazon and Orinoco regions.
Details: Automolus virgatus was originally described as a species in great detail, though without explicit comparison with A. subulatus (Lawrence 1867), with which it has long been considered conspecific (Peters 1951; but see Gill and Wright 2006, IOC v.1.0). However, major vocal differentiation between the A. virgatus and A. subulatus groups (Ridgely and Tudor 1994, Boesman 2016 [No. 90]) with congruent genetic divergence (Schultz et al. 2017) is considered by WGAC and Clements et al. (2023) to be strong evidence for the two-species treatment enacted by del Hoyo and Collar (2016). A 2003 SACC proposal (https://www.museum.lsu.edu/~Remsen/SACCprop40.htm) to split A. virgatus did not pass owing to insufficient published data.
English names: The English names distinguish between the regions inhabited by the two species and align with Gill and Wright (2006, IOC v.1.0).

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.
