Despite superficial resemblance to Phyllomyias, genus appears to be more closely related to Phylloscartes. This species was formerly placed in a separate genus, Tyranniscus, but exhibits plumage and morphological features (wing pattern, proportionally long tail and bill, and derived characters of both syrinx and palate) typical of present genus. Differences among named populations extremely subtle, apparently clinal, and recognizable only as population averages; on the other hand, apparent vocal differences across range imply that more than one taxon may be involved. Further study is required.

The following 3 subspecies are recognised:

• gracilipes (Sclater & Salvin, 1867)   -  South-eastern Venezuela (southern Bolí­var, Amazonas), extreme eastern Colombia (Vichada south to Amazonas), north-western Brazil (Amazonas), eastern Ecuador and north-eastern Peru (Loreto).
• acer (Salvin and Godman, 1883)   -  The Guianas and north-eastern Brazil (eastern Amazonas east to Maranhío, Ceará and Alagoas). Considered by some authors to be a distinct species, Guianan Tyrannulet (Zimmerius acer).
• gilvus (Zimmer, JT, 1941)   -  Western and southern Amazonian Brazil (Amazonas south to Rondônia and northern Mato Grosso), central and south-eastern Peru and northern Bolivia (south to Cochabamba and northern Santa Cruz).
