The genus was erected by the English zoologist Philip Sclater in 1858.[1] The type species is the pygmy antwren.[2]

The genus currently contains the following species:[3]

Streaked group:

Grey group:

Several species previously included in this genus as the "stipple-throated group" have now been transferred to a new genus, Epinecrophylla based on a 2006 study of nest architecture, foraging behaviour and vocal repertoire.[3][4] A molecular genetic study published in 2012 found that the genus was not monophyletic.[5] As a step in creating monophyletic genera, two species that were only distantly related to the other members of Myrmotherula, the rufous-bellied antwren and the plain-throated antwren, were moved to the newly erected genus Isleria.[3][5] A further study published in 2014 confirmed that the species remaining in Myrmotherula formed a paraphyletic group with respect to the genera Terenura, Formicivora, Stymphalornis and Myrmochanes.[6]
