It is known from only a few localities but it is common and its population is stable in suitable habitats.
Loss of habitat due to the expansion of human settlements is a threat to this species, most notably the growth of the city of Corrientes.
It is not known to occur in any protected areas.
Red List Status
Near Threatened (NT)
