Sister to T. murinus (which see). Race heterogynus might merit full species status, but current information insufficient. Two proposed races merged into nominate: dubius (E Peru), which represents intermediate plumage in broad cline; and inornatus (C Brazil), representing end of a cline and intergrading broadly with “typical” nominate. Three subspecies currently recognized.

Subspecies and Distribution
  • T. s. heterogynus (Hellmayr, 1907) – Tefe Antshrike – extreme E Colombia (E Vaupés, presumably this race) and WC Amazonian Brazil (lower R Japurá, middle R Jaú, and both banks of R Solimões from R Juruá and lower and middle R Purus E to R Madeira).
  • T. s. capitalis P. L. Sclater, 1858 – SE Colombia (E base of Andes S from Meta), E Ecuador and NE Peru (N of R Marañón and R Amazon).
  • T. s. schistaceus d’Orbigny, 1837 – Plain-winged Antshrike – EC & SE Peru (S of R Marañón and R Amazon), S Amazonian Brazil (S of lower R Juruá and middle R Purus, and E from R Madeira to R Tocantins, S to Acre, Rondônia, N & W Mato Grosso and S Pará) and N Bolivia (S to C Santa Cruz).
