R. A. Philippi [Krumwiede] and Landbeck, 1864,
Hacienda de la Puerta, 5000 feet [c. 1525 m], Colchagua, Chile.
Close to P. tarnii, and formerly considered conspecific. The two are geographically separated in W Argentina (Neuquén) by a distance of more than 200 km. Contrary to previous belief, the upper R Bío Bío does not represent an effective dispersal barrier, suggesting that the two have been in contact several times during fluctuating climatic conditions; however, they differ significantly in voice, and comparison of mtDNA (albeit based on small sample sizes) indicates genetic isolation for more than 3 million years. Monotypic.
C Chile from Colchagua S to R Bío Bío (at headwaters, only N of R Laja), and immediately adjacent Argentina (W Neuquén).
