FIGURE 1 in Calls distinguish species of Antbirds (Aves: Passeriformes: Thamnophilidae) in the genus Pyriglena

FIGURE 1. Distribution of Pyriglena populations named in text. Symbols represent occurrence of taxa within small geographic sectors (Isler 1997). A = pacifica; B = castanoptera; C = picea; D = marcapatensis; E = hellmayri; F = maura; G = similis; H = interposita; I = leuconota; J = pernambucensis; K = atra; L = leucoptera. Lines around dots identify taxa based on available locational data and do not necessarily reflect the extent of likely geographic range. Lines were not drawn between castanoptera and picea nor between marcapatensis, hellmayri, and maura given uncertainties regarding how their ranges intersect.
