Subspecies
Genus presumed related to Thamnophilus on basis of external morphology, especially the strongly hooked bill, but supporting molecular or other evidence unavailable. Relationships uncertain. Possibly closest to the Thamnophilus doliatus complex. Populations in Bolivia, western Paraguay and north-western Argentina require study. Recent specimens from presumed range of subspecies argentina (in eastern Bolivia lowlands) approach excubitor in paleness, and plumage differences between the two may be clinal. Also, diagnosable differences may possibly be found between lowland and foothill populations.
The following 3 subspecies are recognised:
excubitor Bond & Meyer de Schauensee, 1940 - Central Bolivia (western Santa Cruz).
argentina Shipton, 1918 - Eastern Bolivia (southern Santa Cruz, Chuquisaca, Tarija), western Paraguay (Boquerón, Presidente Hayes) and north-western Argentina (Jujuy, Salta, northern Tucumán).
cinerea (Vieillot, 1819) - South-eastern Brazil (southern Espírito Santo and south-western Sío Paulo south to Santa Catarina and northern Rio Grande do Sul) and north-eastern Argentina (Misiones).
