Subspecies
Relationships to other genera unclear. Species currently placed in genus appear to be related on basis of morphology and behaviour, although their nest architecture is somewhat variable. Forms a superspecies with Cinereous Antshrike (Thamnomanes caesius) and sometimes considered conspecific. Subspecies probably reflect a cline in darkness of plumage, but further study is required.
The following 2 subspecies are recognised:
intermedius Carriker, 1935 - Central Peru south of R Amazon and east of R Huallaga (south to Junín).
schistogynus Hellmayr, 1911 - Western Brazil south of R Amazon (west of lower R Juruá and south to its middle and upper reaches and to upper R Purus), south-eastern Peru (southern from Junín) and north-western Bolivia (western Pando, La Paz, Cochabamba).
