Vipera aspis atra is a venomous viper subspecies[3] endemic to France, Switzerland and Italy.

[4] It is found in western Switzerland, northwestern Italy, Spain, and southeastern France.

[4] Mallow et al. (2003) describe the range only as "portions of Switzerland".

[5] This subspecies is classified as Vulnerable (VU) according to the IUCN Red List of Threatened Species (v3.1, 2001).

[6][7] A recent study by Ursenbacher et al. (2006) suggests that V. a. atra may not be a valid subspecies.
