Griseotyrannus? Crowned Slaty Flycatcher (1 Viewer)

There is a recent report published of a Crowned Slaty-Flycatcher in Louisiana last year.
http://www.aba.org/nab/v62n4p638.pdf .
In the article they put the bird in the Empidonomus genus. If you search wikipedia for Crowned Slaty-Flycatcher they have it in Griseotyrannus. This is from a 1984 article by W. Lanyon A Phylogeny of the kingbirds and their allies available here:
http://digitallibrary.amnh.org/dspace . Looking quickly it is based on sphyringeal characteristics.
In the SACC list is footnote 130:
130. Lanyon (1986) provided morphological data for placing aurantioatrocristatus in a monotypic genus, Griseotyrannus, and this treatment was followed by Fitzpatrick (2004). Proposal needed?

Looking at genebank there is genetic stuff available for Empidonomus varius and Griseotyrannus from two 2008 articles:
Molecular taxonomy of Brazilian tyrant-flycatchers.
http://www3.interscience.wiley.com/journal/121410291/abstract .
and Tyrant flycatchers coming out in the open: phylogeny and ecological radiation of Tyrannidae
http://www3.interscience.wiley.com/journal/119401930/abstract .
So has anyone read either article and do they address the Griseotyrannus question?

The SACC 1986 cite may be A Phylogeny of the Thirty-Three Genera in the
Empidonax Assemblage of Tyrant Flycatchers, also available at the
http://digitallibrary.amnh.org/dspace .

I believe the Lanyon citation is from "A phylogeny of the kingbirds and their allies. American Museum novitates ; no. 2797"

The abstract reads in part "A phylogeny is developed for those genera of tyrant flycatchers known as the kingbirds and their allies: Pitangus, Megarynchus, Myiozetetes, Conopias, Myiodynastes, Legatus, Empidonomus, Tyrannopsis, and Tyrannus. Monophyly of the assemblage is established by two shared derived character states of the skull. ........ Three new monotypic genera are recognized: Phelpsia for Conopias inornata, Philohydor for Pitangus lictor, and Griseotyrannus for Empidonomus aurantioatrocristatus. A classification of the 12 genera recognized in this assemblage might reasonably follow this sequence, based on the relationships demonstrated here: Tyrannus, Empidonomus, Griseotyrannus, Tyrannopsis, Megarynchus, Conopias, Myiodynastes, Myiozetetes, Legatus, Philohydor, Pitangus, and Phelpsia"--P. [1].

The abstract can be found at http://digitallibrary.amnh.org/dspa...full&submit_simple=More+bibliographic+detail+ and the full PDF at http://digitallibrary.amnh.org/dspace/bitstream/2246/5271/1/N2797.pdf

Although Howard & Moore 1991, Monroe & Sibley 1993, Mobley 2004 (HBW 9) and IOC follow Lanyon in placing Crowned Slaty Flycatcher in Griseotyrannus, it is retained in Empidonomus by Dickinson 2003 (H&M 3), BirdLife International and Cornell/Clements (as well as by AOU-SACC, pending possible proposal).

Dickinson (2003) notes: "Treated in the monotypic genus Griseotyrannus in last Edition, but a sister species of E varius see Traylor (1979) and better kept with that (J.V. Remsen, in litt.)".
