World distribution. Peru and Chile.

Chilean distribution. From Arica y Parinacota to Tarapacá region ( Fig. 147 ).

Altitudinal range. This species inhabits mainly highland ecosystems (3,000 –4,200 m.a.s.l.).

Biology and notes. Copestylum yura is associated with xeric conditions and Andean grasslands or shrublands in the highlands. It can be observed throughout the transition between the Atacama and Puna province in Chile ( Morrone 2014). Habitat loss due to mining and water exploitation as well as climate change are the major threats for this species. Other aspects of its biology and ecology remain unknown in Chile.

Conservation status. EN under B1ab (iii) + 2ab (iii) using EOO = 1,865 km 2, AOO = 20 km 2 and five localities (or subpopulations).

Subgenus Tachinosyrphus Hull, 1936
