In past, placed in Mecocerculus. Vocal similarities and plumage (rufous above lores) suggest it may be a member of the “P. flaviventris group” (which see). Geographical variation minor; validity of races impossible to assess, as so few specimens available. Three subspecies tentatively recognized.

Subspecies and Distribution
  • P. s. superciliaris (P. L. Sclater & Salvin, 1868) – forested mountains of Costa Rica and W Panama.
  • P. s. palloris (Griscom, 1935) – E Panama (Darién) and NW Colombia#R.
  • P. s. griseocapillus Phelps, Sr & Phelps, Jr, 1952 – very locally in Sierra de Perijá (along Venezuela–Colombia border), N Colombian Andes, and E slopes in E (recent sight record from Napo) & SE Ecuador (Cordillera de Cutucú, Cordillera del Cóndor) and adjacent N Peru.
