Tephrocactus verschaffeltii, until recently better known as Austrocylindropuntia verschaffeltii, has hitherto only been known from Argentina and Bolivia. A single population discovered growing at 3660m in the department of Moquegua, Peru is approximately 400km distant from the next known population in the department of La Paz in Bolivia. This new population confirms Tephrocactus verschaffeltii as a member of the Peruvian flora and Tephrocactus as a new generic record for Peru.
