Subspecies
Forms a superspecies with Castelnau's Antshrike (Thamnophilus cryptoleucus) and formerly considered conspecific. Subspecies distinctive in plumage. Furthermore, differences among them in calls, and also the possibility that Amazonian subspecies may meet each other without intergradation, require study.

The following 5 subspecies are recognised:

  • cinereoniger Pelzeln, 1868   -  North-eastern Colombia, south-western Venezuela and north-western Amazonian Brazil (drainages of, respectively, R Meta, upper R Orinoco, and lower R Uaupés and R Negro).
  • tschudii Pelzeln, 1868   -  West-central Brazil (eastern Amazonas along lower R Madeira).
  • huberi Snethlage, E, 1907   -  East-central Brazil (western Pará along lower R Tapajós).
  • nigrocinereus Sclater, 1855   -  Eastern Brazil from near mouth of R Tapajós along lower R Amazon and surrounding rivers east to Amapá and islands in estuary.
  • kulczynskii (Domaniewski & Stolzmann, 1922)   -  Eastern French Guiana and adjacent Brazil (extreme northern Amapá).
