Typical Antbirds (Thamnophilidae)

Barred Antshrike (Thamnophilus doliatus) - HBW 8, p. 545

French: Batara rayé German: Bindenameisenwürger Spanish: Batará Barrado

Taxonomy: Lanius doliatus Linnaeus, 1764, no locality = Surinam.
Belongs to a species group which also includes T. zarumae, T. multistriatus, T. tenuepunctatus, T. palliatus, T. torquatus and T. ruficapillus. Forms a superspecies with first of those and formerly treated as conspecific, but differs in morphology and vocalizations. Taxonomy of present species in need of study and possible revision; races may constitute more than one species; further, plumage varies considerably within many races, apparently in clinal pattern, and comparisons of morphology with molecular and other characters needed to reconfirm validi..

Taxonomy: Lanius doliatus Linnaeus, 1764, no locality = Surinam.
Belongs to a species group which also includes T. zarumae, T. multistriatus, T. tenuepunctatus, T. palliatus, T. torquatus and T. ruficapillus. Forms a superspecies with first of those and formerly treated as conspecific, but differs in morphology and vocalizations. Taxonomy of present species in need of study and possible revision; races may constitute more than one species; further, plumage varies considerably within many races, 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 races are yucatanensis (S Mexico, N Guatemala) and pacificus (W Honduras to W Costa Rica), which appear inseparable from intermedius; fraterculus (E Colombia, N Venezuela, Trinidad), considered indistinguishable from nominate; and subradiatus (E Peru, W Brazil), novus (Mato Grosso) and signatus (NE Bolivia, SW Brazil), which appear inseparable from radiatus. In addition, birds from N Colombia, formerly considered a disjunct population of nigricristatus, intergrade with albicans and are therefore included with latter. Twelve subspecies recognized.

Subspecies and Distribution:

  • intermedius Ridgway, 1888 - E Mexico (SE from S Tamaulipas and San Luis Potosí and, on Pacific slope, E from Oaxaca), Belize and Guatemala S to W Panama (W Chiriquí, Bocas del Toro).
  • nigricristatus Lawrence, 1865 - C Panama (E Chiriquí and S Veraguas E to W San Blas).
  • eremnus Wetmore, 1957 - Coiba I, S Panama.
