In past, often placed with the Epinecrophylla haematonota group (the “stipple-throated antwren assemblage”, itself formerly included in Myrmotherula) mainly because of its dotted throat, but that link was undermined by finding of a cup nest (rather than globular). Recent genetic and morphological analysis#R indicates present species is not close to any of those species, but is probably sister to Dichrozona and also to Thamnomanes and some other antshrike genera; in addition, its behaviour suggests that it may be related to recently erected genus Isleria (also previously part of Myrmotherula). Monotypic.

Distribution:

SE Brazil in coastal region from SE Bahia S to Santa Catarina and NE Rio Grande do Sul, extending inland in S to W Paraná.
