Subspecies
Thamnophilus doliatus (Sibley and Monroe 1990, 1993) has been split into Barred Antshrike (Thamnophilus doliatus) and Chapman's Antshrike (Thamnophilus zarumae) following SACC (2005).
Belongs to a species group which also includes Chapman's Antshrike (Thamnophilus zarumae), Bar-crested Antshrike (Thamnophilus multistriatus), Chapman's Antshrike (Thamnophilus zarumae), Chestnut-backed Antshrike (Thamnophilus palliatus), Rufous-winged Antshrike (Thamnophilus torquatus) and Southern Rufous-capped Antshrike (Thamnophilus ruficapillus). Forms a superspecies with Chapman's Antshrike (Thamnophilus zarumae) and formerly treated as conspecific, but differs in morphology and vocalizations. Subspecies may constitute more than one species; further, plumage varies considerably within many subspecies, apparently in clinal pattern, and comparisons of morphology with molecular and other characters needed to reconfirm validity of many taxa; current treatment tentative. Other described subspecies are yucatanensis (southern Mexico, northern Guatemala) and pacificus (western Honduras to western Costa Rica), which appear inseparable from intermedius; fraterculus (eastern Colombia, northern Venezuela, Trinidad), considered indistinguishable from nominate; and subradiatus (eastern Peru, western Brazil), novus (Mato Grosso) and signatus (north-eastern Bolivia, south-western Brazil), which appear inseparable from radiatus. In addition, birds from northern Colombia, formerly considered a disjunct population of nigricristatus, intergrade with albicans and are therefore included with latter.
The following 12 subspecies are recognised:
intermedius Ridgway, 1888 - Eastern Mexico (south-eastern from southern Tamaulipas and San Luis Potosí and, on Pacific slope, eastern from Oaxaca), Belize and Guatemala south to western Panama (western Chiriquí, Bocas del Toro).
nigricristatus Lawrence, 1865 - Central Panama (eastern Chiriquí and southern Veraguas east to western San Blas).
eremnus Wetmore, 1957 - Coiba I, southern Panama.
nesiotes Wetmore, 1970 - Pearl Is, southern Panama.
albicans Lafresnaye, 1844 - Northern and western Colombia (Caribbean slope from Antioquia and Córdoba east to La Guajira, and southern in Magdalena Valley to Huila).
nigrescens Lawrence, 1867 - North-central Colombia east of Andes (Norte de Santander) and north-western Venezuela north of Andes (Zulia, Táchira, western Mérida).
tobagensis Hartert & Goodson, 1917 - Tobago.
doliatus (Linnaeus, 1764) - North-eastern Colombia (south to Caquetá and Guianía), Venezuela (except in north-western and, apparently, southern Bolívar and eastern Amazonas, but including Margarita I), Trinidad, the Guianas, and northern Amazonian Brazil (extreme northern Amazonas on upper R Negro, Roraima, Amapá, and northern Pará from vicinity of R Trombetas east to Marajó I).
radiatus Vieillot, 1816 - Extreme south-eastern Colombia (southern Amazonas), north-eastern Ecuador (Napo), eastern Peru (except northern Amazonas and western Loreto), western and south-central Brazil (northern bank of R Amazon east to vicinity of R Trombetas and, south of R Amazon, east to right bank of R Tapajós and R Aripuaní in western Pará and south to Acre, Mato Grosso do Sul, western Paraná and Sío Paulo), northern and eastern Bolivia, Paraguay and northern and north-eastern Argentina (Salta, Formosa, Santa Fe, Misiones).
cadwaladeri Bond & Meyer de Schauensee, 1940 - Southern Bolivia (Tarija).
difficilis Hellmayr, 1903 - East-central Brazil (eastern Maranhío, south-western Piauí and extreme south-eastern Pará south to eastern Mato Grosso, western and southern Goiás and extreme western Bahia).
capistratus Lesson, R, 1840 - Eastern and southern Piauí, Ceará and Rio Grande do Norte south to extreme northern Minas Gerais and central Bahia.
