Traditionally considered closest to T. forficatus (which see). Phylogenetic analyses suggest present species might belong with T. niveigularis species-group (which see), although relationships remain uncertain. Four subspecies currently recognized.

Subspecies and Distribution
  • T. s. monachus Hartlaub, 1844 – S Mexico (C & S Veracruz, N Oaxaca, NE Chiapas, Tabasco, SW Campeche) S to Colombia (except N, but generally E of Andes S to Meta and Vichada) and much of Venezuela (E to Orinoco Delta, S to N Amazonas and N Bolívar, and several offshore islands); also S Suriname (Sipaliwini) and NC Brazil (Roraima, lower R Negro, perhaps Amapá).
  • T. s. sanctaemartae (J. T. Zimmer, 1937) – N Colombia (Caribbean coastal region and Santa Marta Mts area) and extreme NW Venezuela (NW Zulia).
  • T. s. circumdatus (J. T. Zimmer, 1937) – N Brazil in E Amazonas (occasionally W to Manaus) and Pará and Amapá (S bank R Amazon, islands near Santarém, and both banks of R Tapajós).
  • T. s. savana Daudin, 1802 – C, S & SE Brazil (Rondônia and S Mato Grosso E to Tocantins and S Piauí, S to Mato Grosso do Sul, Minas Gerais, Rio de Janerio and Rio Grande do Sul), N & E Bolivia, Paraguay, Argentina (S to Río Negro, occasionally to NE Chubut and even Patagonia) and Uruguay; S populations migrate N to Colombia, Venezuela, the Guianas and Amazonia.
