Subspecies
Genus appears not to represent a monophyletic grouping, but traditional arrangement maintained pending further phylogenetic study. Relationships uncertain. Plumage differences among some subspecies may reflect clinal variation.

The following 5 subspecies are recognised:

  • exsul Sclater, 1859   -  Caribbean slope from Nicaragua south to western Panama (east to Canal region in Colón).
  • occidentalis (Cherrie, 1891)   -  Pacific slope in Costa Rica and western Panama (Chiriquí­, Veraguas).
  • niglarus (Wetmore, 1962)   -  Eastern Panama (from Colón east of Canal, and Pacific slope in Panamá and north-western Darién) and adjacent extreme north-western Colombia (northern Chocó).
  • cassini (Ridgway, 1908)   -  Extreme south-eastern Panama (Darién south of Golfo de San Miguel) and northern Colombia (northern Chocó east to southern César and lower Magdalena Valley south to Bolí­var). Considered by some authors to be a subspecies of Short-tailed Antbird (Poliocrania maculifer).
  • maculifer (Hellmayr, 1906)   -  Pacific slope in west-central and south-western Colombia (southern from central Chocó) and western Ecuador. Considered by some authors to be a subspecies of Short-tailed Antbird (Poliocrania maculifer).
