Subspecies
Myrmotherula surinamensis (Sibley and Monroe 1990, 1993) has been split into Guianan Streaked Antwren (Myrmotherula surinamensis), Pacific Antwren (Myrmotherula pacifica) and Amazonian Streaked Antwren (Myrmotherula multostriata) following SACC (2005).
Considered a sister-species of Guianan Streaked Antwren (Myrmotherula surinamensis) and until recently was treated as conspecific with that and also with Pacific Antwren (Myrmotherula pacifica), but vocal and plumage characters indicate that they represent three separate species. Genetic and morphological analyses indicate that all are part of a monophyletic group that also includes Pygmy Antwren (Myrmotherula brachyura), Moustached Antwren (Myrmotherula ignota), Cherrie's Antwren (Myrmotherula cherriei), Klages's Antwren (Myrmotherula klagesi), Stripe-chested Antwren (Myrmotherula longicauda), Sclater's Antwren (Myrmotherula sclateri) and Yellow-throated Antwren (Myrmotherula ambigua) (the "streaked antwren assemblage").
