Whitney, Isler, Bravo, Aristizábal, Schunck, Silveira & Piacentini 2013. A new species of Epinecrophylla antwren from the Aripuanã-Machado interfluvium in central Amazonian Brazil with revision of the "stipple-throated antwren" complex. HBW SV 263–267.
  • Epinecrophylla (haematonota) haematonota - Napo Stipple-throated Antwren (incl fjeldsaai)
  • Epinecrophylla (haematonota) pyrrhonota - Negro Stipple-throated Antwren
  • Epinecrophylla (haematonota) amazonica - Madeira Stipple-throated Antwren
  • Epinecrophylla (haematonota) dentei sp nov - Roosevelt Stipple-throated Antwren
Ref: 15 New species of birds discovered in Amazonia.

AOU-SACC Proposal #589 (Isler, Oct 2013): Split Epinecrophylla haematonota into four species.

AOU-SACC Proposal #590 (Isler, Oct 2013): Treat Epinecrophylla fjeldsaai as a subspecies of E. haematonota.

Thanks for posting the second proposal. I've been wondering the last few weeks why E. fjeldsaai should be included in E. haematonota.
 
Isn't using the name Madeira potentially difficult as it could be confused with the island? Obviously if you know anything about birds you know that there are no Antwrens on Madeira or Firecrests in South America, but I thought checklists liked to keep such ambiguity to a minimum.

I suppose 'Rio Madeira Antwren' would be a better fit?
 
Cyclical approaches to taxonomy?

It's interesting to contrast the rough ride at SACC to some of the HBW splits and new treatments, even some of the better supported ones, with the way the committee bizarrely went out on a limb to support the work of some of the same authors in the controversial Brazilian tapaculos proposal. Not saying they are wrong on the latter, as who knows, but such strong endorsement of the side with the novel taxonomic proposal was strange.

And at the same time, one can contrast the cordial and supportive approach to pending proposals based on publications from Conservacion Colombiana with a "make up the facts to suit the conclusions and rant" approach of some committee members and proposal authors to previous publications from the same journal.

Perhaps an interesting but human response to comments here and elsewhere on committee members' past approaches? I am concerned that the pendulum may have swung too far the other way though. The soon-to-be-rejected obamai sp nov and this suggested lump in particular look pretty solid compared to some other proposals the committee has supported.

TiF Update April 27:
Stipple-throated Antwren, Epinecrophylla haematonota is split into Napo Stipple-throated Antwren, Epinecrophylla haematonota, Negro Stipple-throated Antwren, Epinecrophylla pyrrhonota, and Madeira Stipple-throated Antwren, Epinecrophylla amazonica based on Whitney et al. (2013d).
 
TiF Update May 24:
I've split the Roosevelt Stipple-throated Antwren, Epinecrophylla dentei, from Madeira Stipple-throated Antwren, Epinecrophylla amazonica, based on the recent SACC decision ##589B and Whitney et al. (2013d).

Re Roosevelt Stipple-throated Antwren

I hope that the IBC don't mind me doing this but the photo of the Roosevelt Stipple-throated Antwren on the link has a terrible colour cast. I attach a corrected version to the right of the original.

Brown-backed Antwren

Isler M.L. & Whitney B.M., 2018. Reevaluation of the taxonomic positions of Epinecrophylla fjeldsaai (Aves: Passeriformes: Thamnophilidae) and its geographic neighbors based on vocalizations. Wilson J. Orn.

Abstract

The northwestern populations in the dead-leaf-foraging Epinecrophylla haematonota complex of thamnophilid antwrens includes E. pyrrhonota, E. fjeldsaai, and E. haematonota. Their taxonomic position has been the subject of recent debate. Divergence in homologous vocalizations provides a principal measure of reproductive isolation and species status for thamnophilid antbirds under the biological species concept, but until recently their evaluation as species has been hampered by the paucity of recordings of E. fjeldsaai. That insufficiency has been remedied, enabling an analytic comparison of vocalizations of the 3 taxa. The results of this analysis led to the recommendation that the 3 taxa be ranked as subspecies of Epinecrophylla haematonota.
