In Bolivia in 1992 I tape-recorded and observed several individuals of an undescribed tapaculo of the systematically complex genus Scytalopus in humid-temperate forest near the city of La Paz. During March 1993, Bolivian colleagues and I collected a series of the undescribed taxon from two geographically distinct regions of Depto. La Paz, and confirmed its presence as far south as Prov. Chapare, Depto. Cochabamba. The new species, the Diademed Tapaculo (Scytalopus schulenbergi), is described and its distribution and vocalizations are compared with some other members of the genus, mostly in Bolivia. I reexamine systematics of the magellanicus group and, based primarily upon striking and consistent vocal differences across the North Peruvian Low in northwestern Peru, I recommend its division into two superspecies with the names magellanicus (southern populations) and griseicollis (northern populations).
