Subspecies
Formerly considered quite closely related to Geothlypis or Dendroica, and was also believed to be close to similarly monotypic Xenoligea. Recent genetic and morphological evidence suggests that both latter and present species may belong, instead, with the tanagers (Thraupidae). Population of this species recently found in xeric lowlands of north-western Haiti may represent an additional, as yet undescribed, subspecies.
The following 2 subspecies are recognised:
palustris (Cory, 1884) - Highlands of Hispaniola.
vasta Wetmore & Lincoln, 1931 - Xeric lowlands of south-western Dominican Republic.
