Subspecies
Thamnomanes ardesiacus (Sibley and Monroe 1990, 1993) has been split into Saturnine Antshrike (Thamnomanes saturninus) and Dusky-throated Antshrike (Thamnomanes ardesiacus) following SACC (2005).
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. Sometimes been placed in genus Dysithamnus. Forms a superspecies with Dusky-throated Antshrike (Thamnomanes ardesiacus) and has been treated as conspecific. A taxonomic study of populations is needed. Extent of geographical ranges of subspecies unclear; huallagae may not be distinguishable from nominate.
The following 2 subspecies are recognised:
huallagae (Cory, 1916) - North-eastern Peru south of R Amazon (along southern bank of R Marañón to R Huallaga, and south to R Ucayali in southern Loreto) and south-western Amazonian Brazil (drainage of upper R Juruá, south to western Acre).
saturninus (Pelzeln, 1869) - South-central Amazonian Brazil (from lower R Juruá and upper R Purus east to western bank of R Tapajós and both banks of R Teles Pires) south to Rondônia, northern Mato Grosso and extreme north-eastern Bolivia (north-eastern Santa Cruz).
