World distribution. Peru and Chile.

Chilean distribution. From Arica y Parinacota to Valparaíso region ( Fig. 146 ).

Altitudinal range. From inland valleys to highland ecosystems (600– 4,500 m.a.s.l.).

Biology. Copestylum peruvianum is associated with native flora from highlands of the Andes. Mining, water exploitation and climate change are the main threats for this species. Other aspects of its biology and ecology remain unknown in Chile.

Conservation status. VU under B2ab (iii) using AOO = 44 km 2 and nine localities (or subpopulations); EOO = 49,306 km 2.
