Note. Bruch (1912) recorded this species from Catamarca and Misiones, but the specimens of his collection are labelled as being from Corrientes and Córdoba. Bosq (1949) expressed his doubts that Obrium multifarium are present in Santiago del Estero ( Prosen 1947), but examination of material confirms its presence in this province.
