Pristidactylus volcanensis, a new species from El Volcán, Cordillera de Los Andes, unlike its congeners previously reported for Chile, is not associated with Notophagus forest. It is distinguished from the other Chilean and Argentinean Pristidactylus by coloration, squamation, measurements, and habitus. Males and females have a primitive karyotype of 12 macrochromosomes and 24 microchromosomes. An hypothetical evolutionary mode of speciation is discussed.
