Similar Species
Very similar to Guianan Streaked Antwren (Myrmotherula surinamensis) and Cherrie's Antwren (Myrmotherula cherriei), though only sympatric with the former. Male Streaked has a semi-concealed white dorsal patch (very hard to see in the field). Female differs from Streaked in having crown primarily black streaked buff not orange-rufous streaked black. Also lacks black streaking on the throat, though this can be very fine and hard to see on Streaked.
