Myrmotherula ignota has two subspecies:

  • M. i. ignota
  • M. i. obscura
  • South-central and eastern Colombia to north-eastern Peru and western Amazonian Brazil
  • Regarded as a separate species, the Short-billed Antwren Myrmotherula obscura, by some authorities.


Subtropical or tropical moist lowland rainforests, subtropical or tropical swamps, and heavily degraded former forest.


This species tends to fourage high towards the canopy while the Plain-throated Antwren fourages at lower levels, at least if both species are present.
