Synallaxis ruficapilla infuscata
O. M. O. Pinto, 1950,
Usina Nossa Senhora do Carmo, Vitória de Santa Antão, eastern Pernambuco, Brazil.
Thought to form a group with S. ruficapilla and S. cinerea; this group sometimes suggested as being most closely related to S. frontalis, S. azarae and S. courseni on basis of plumage and vocal similarities, although recent (but incomplete) phylogeny#R found evidence to suggest that S. moesta from E Andean foothills is more closely related to the group. Until relatively recently, present species was considered a race of S. ruficapilla, but vocal differences indicate that it merits species rank; some authors have proposed that it is more closely related to S. brachyura or S. hypospodia. Monotypic.
