Subspecies
Affinities of genus uncertain; plumage features suggest possible relationship to Phleocryptes and to sympatric Pygarrhichas. Close to, and perhaps ancestor of, Mas Afuera Rayadito (Aphrastura masafucrae). Validity of subspecies bullocki, described from only two specimens, perhaps requires reconfirmation. Also, individuals with ochraceous underparts, thus resembling fulva, evidently occur throughout near-shore Chilean islands, suggesting that this ventral pattern may appear independently in insular populations as response to more humid conditions (Gloger's Rule). In addition, population on Diego Ram��rez I apparently differs morphologically from typical nominate form. Further study needed in order to clarify geographical limits and validity of subspecies.

The following 3 subspecies are recognised:

spinicauda (Gmelin, 1789) - Central and southern Chile (southern from southern Coquimbo) and extreme western Argentina (southern from Neuqu�n) south to Tierra del Fuego, Staten I and Diego Ram��rez I. Also Falkland Is.
bullocki Chapman, 1934 - Mocha I, off south-central Chile.
fulva Angelini, 1905 - Chilo� I, off south-central Chile.
