Mazar Barnett and Buzzetti

, 2014,

Serra Branca, Murici, 09°15’ S, 35°50’ W, 550 m above sea-level, Alagoas, Brazil


Recently named species, description based on a female specimen from 1986#R; not universally accepted as valid. Remarkably similar in appearance to sympatric Philydor novaesi, but thorough morphometric analysis#R supports its placement in present genus, within which its appearance is highly distinctive; genetic analysis needed. Monotypic.


Known only from two localities in NE Brazil (Murici, in Alagoas, and Frei Caneca, in Pernambuco); no records since 2007, perhaps extinct#R.
