Other common names: Chicli Spinetail

Taxonomy: Synallaxis Spixi P. L. Sclater, 1856, São Paulo, Brazil.
Close relationship to S. albescens and S. albigularis suggested by plumage and vocal similarities. In the past was considered conspecific with S. hypospodia; the two are thought to be possibly sister-species by some authors, but others consider them not closely related because of differences in tail morphology, throat pattern and voice. Monotypic.
