Etymology:
The specific epithet, eremicus (from Latin, eremic = of the desert, lonely), which is a geographical adjective that is derived from this species apparently being endemic to the Uspallata-Calingasta valley, which is an isolated high elevation valley in the Monte Desert that lies between the Precordillera on the east and the Andean Cordillera on the west. This valley has also been referred to as the Eremean District (Roig, Roig-Juñent & Corbalán, 2009).
