ectus to species rank: Automolus rufipectus, Santa Marta Foliage-gleaner.
There are a few interesting notes on sounds in the proposal, taken from the paper by Niels Krabbe that was the basis of the proposal:
KRABBE, N. 2008. Vocal evidence for restitution of species rank to a Santa Marta endemic: Automolus rufipectus Bangs (Furnariidae), with comments on its generic affinities. Bulletin British Ornithologists' Club 128: 219-227. (link to pdf)
SACC:Krabbe (2008) taped four individuals of A. r. rufipectus and gathered recordings of two others; these were compared to sonograms of all other Automolus and related genera. The songs and calls of rufipectus differ from those of 8 subspecies (no recordings available for 5) of A. rubiginosus in multiple ways, and Krabbe summarized reasons why the unsampled subspecies should not differ from those sampled. In contrast, the song of rufipectus actually resembles that of Hylocryptus erythrocephalus of the Tumbesian region more than that of any other species. Making that link even more tantalizing is Krabbe's observations of rufipectus feeding mostly on the ground (albeit small N) and its preference for semihumid forest.
Let's see which subspecies of A.rubiginosus exist
guerrerensis (Salvin & Godman, 1891) - SW Mexico (Guerrero, W Oaxaca).
rubiginosus (P. L. Sclater, 1857) - mountains of E Mexico (Veracruz).
veraepacis (Salvin & Godman, 1891) - mountains from S Mexico (E Oaxaca, Chiapas) and Guatemala E to N Nicaragua.
fumosus (Salvin & Godman, 1891) - mountains of extreme SW Costa Rica and W Panama (Chiriqui, San Blas).
saturatus (Chapman, 1915) - highlands of extreme E Panama (Darien) and NW Colombia (Antioquia).
rufipectus (Bangs, 1898) - Santa Marta Mts, in N Colombia.
nigricauda (Hartert, 1898) - W Colombia (Baudo Mts, and foothills of W Andes) S to W Ecuador (S to El Oro) and narrowly to N Peru (Tumbes).
sasaimae (Meyer de Schauensee, 1947) - E Andes of Colombia (W slope in Boyaca and Cundinamarca).
cinnamomeigula (Hellmayr, 1905) - SW Venezuela (Apure) and foothills of E Colombian Andes (Meta).
caquetae (Meyer de Schauensee, 1947) - foothills of E Andes in S Colombia (Narino, Caqueta, Putumayo) and NE Ecuador (Sucumbios).
brunnescens (Berlioz, 1927) - foothills from E Ecuador (S from Napo) S to NE Peru (Amazonas).
watkinsi (Hellmayr, 1912) - Andean foothills
Cool place with lots of greenerys and surrounded with small rivers
