Resumen
In the present work we are reporting for the first time the presence of D. nebulosa in San Juan province enlarging in a south-western direction its Andean distributional range. Our sampling site, San Agustín del Valle Fértil (30° 38’ 1” S, 67° 27’ 59” W) is located at 250 km north-east of the capital city of the province, San Juan. This zone belongs to the Phytogeographic Province known as Monte (Cabrera, 1971) with a vegetation typical of a shrub steppe adapted to warm and arid weather, with periodic droughts of 6 to 9 months a year and mean annual precipitation of 200-250 mm (Mirré, 1976). The vegetation is of a xeric environment, with scarce arboreal vegetation, mainly represented by “algarrobos” (genus Prosopis), and cacti of Echinopsis (cardon) and Opuntia (prickly pear) genera.
