World distribution. Argentina and Chile. Chilean distribution. From Arica y Parinacota to Antofagasta region (Fig. 39). Altitudinal range. Recorded only in highlands ecosystems (3,000 –4,000 m.a.s.l.). Biology and notes. A native species that inhabits highlands mainly associated with salt lakes and wetlands. Habitat loss, pollution and climate change probably are the main drivers of its decline. This species has not been collected since the 1960s, and all basic aspects of its biology and ecology remain unknown in Chile. Conservation status. EN under B2ab (iii) using AOO = 20 km 2 and five localities (or subpopulations); EOO = 31,851 km 2.
