Grallaria guatimalensis

See also G. chthonia (above). Races carmelitae and sororia only doubtfully distinct from regulus; moreover, distributional limits of the last two in C & S Peru remain to be clarified. Race binfordi said to resemble ochraceiventris and often synonymized with it, but has vertical stripes on breast; binfordi has even been proposed for phylogenetic species rank#R, as also have races ochraceiventris and guatimalensis#R. Birds from N end of range described as race mexicana, but normally included in highly variable nominate race. Birds from Margarita I (NE Venezuela) may be a separate race#R; name schwartzii has been suggested, but this name has never been formally introduced#R. Authorship and date of species name recently corrected#R. Ten subspecies recognized.
