Discussion
Distribution and Ecology: A rare species, known from Ecuador (Galäpagos Is. (Isabela)), Peru (Loreto (Bryan, 1929)), Bolivia (s. loc., Herzog, 1921), Chile (Valparaiso, O’Higgins (Montagne, 1850)), and Argentina (Catamarca (Hässel de Menéndez, 1963), Salta, Tucuman (Grassi, 1976)). It has been collected on bare, gravelly, volcanic soil among grassy vegetation or under bushes in rather dry and cool, high mountain environments, in the Andes from 2150 to 4000 m, and at lower elevations (1400 m) in pampas vegetation on the Galapagos Islands (Gradstein et al., 2001).
