Peru = Junín.
Normally placed in Anas; with S. hottentota and S. versicolor sometimes placed in genus Punanetta. Taxon puna, traditionally included within S. versicolor, often considered a full species, and this arrangement supported here on basis of its larger bill (mean male 50 vs 39 and 42 respectively#R) (at least 2); no yellow on bill (2); paler dark markings on breast and upperparts (1); barring on lower underparts starting at mid-belly, being denser and becoming paler and less defined on uppertail and undertail, so that tail appears plain grey rather than densely barred black and white (cumulative effect of three minor characters: 3). Monotypic.
Andean C Peru (from S Amazonas#R) S to N Chile (Antofagasta) and extreme NW Argentina.
