Myrmotherula paraensis ochrogyna Todd, 1927

Includes the study subpopulation designated ochrogyna in the analysis.

Diagnosis. Myrmotherula paraensis ochrogyna is distinguished from M. p. paraensis and M. p. transitiva by diagnosable differences in female plumage provided in the description of M. paraensis .

Distribution. Brazil east of the Rio Madeira, south of the Rio Amazonas, and west of the Rio Tapajós and Rio Teles Pires. Southern limits are uncertain.

Remarks. This subpopulation is considered a subspecies of M. paraensis , rather than a species, based on the absence of vocal differences with the nominate, a conclusion supported by the genetic results. Refer to additional remarks under M. p. transitiva.
