Philydor novaesi Teixeira & Gonzaga

Alagoas Foliage-Gleaner (Philydor novaesi)

The Alagoas Foliage-Gleaner was described in 1983, it was restricted to the states of Alagoas and Pernambuco in northeastern Brazil, where it preferablky inhabited tropical lowland forest but was also found in second-growth forest at elevations of up to 400 to 550 m.

The species apparently was most closely related to the Black-capped Foliage-gleaner (Philydor atricapillus (Wied)) (see photo), it reached a size of about 18 cm and was mainly inconspicuously brown colored.

The Alagoas Foliage-Gleaner has disappeared from its former distribution area due to habitat destruction mainly by forest clearance for agricultural purposes, since 2018 it is considered most likely extinct.

Cichlocolaptes mazarbarnetti Mazar Barnett & Buzzetti

Cryptic Treehunter (Cichlocolaptes mazarbarnetti)

The Cryptic Treehunter is an enigmatic species that is currently included in this genus following thorough morphometric analyses, however, it differs strikingly from the other two species in this genus and superficially resembles the Alagoas Foliage-Gleaner (Phylidor novaesi Teixeira & Gonzaga) with which it occurred sympatrically.

***

The Cryptic Treehunter was restricted to two localities in the states of Alagoas and Pernambuco, Brazil, where it inhabited the last surviving remnants of the former rainforest.

The species reached a size of about 21 cm. 

The Cryptic Treehunter was described in 2014, just seven years after it was last seen, the species is now considered most likely extinct.

Upucerthia dumetaria ssp. peruana Zimmer

Peruvian Scale-throated Earthcreeper (Upucerthia dumetaria ssp. peruana)

The Peruvian Scale-throated Earthcreeper, one of three subspecies of the Scale-throated Earthcreeper (Upucerthia dumetaria I. Geoffroy Saint-Hilaire) (see photo), was described in 1954 based on two specimens that had been collected in the 1950s in the Puno region in the Andes of southern Peru.

The Peruvian Scale-throated Earthcreeper apparently was the largest of the three subspecies, reaching a size of about 21,5 cm, it is also said to have been darker colored than the other forms.

There are apparently no recent records of this form and it is sometimes thought to be already extinct, however, its type locality is huge and it might still be rediscovered some day. [1]
