Habitat. Dry or seasonal thorn scrub or thickets of the Dry Chaco at elevations above 1000 m. Typical habitat of the Chacoan Fat-tailed Opossum has been described as xerophytic woodlands, with dominance of low, thorny, deciduous trees, including “ quebracho ” (Schinopsis sp. and / or Aspidosperma quebracho-blanco, Apocynaceae), “ palo santo ” (Bulnesia sarmientoi, Zygophyllaceae), “ palo borracho ” (Ceiba insignis, Malvaceae), and “ labon ” (Tabebuia nodosa, Bignoniaceae), and typical understory with “ algarrobo ” (Prosopis, Fabaceae), Maytenus (Celastraceae), Mimosa (Fabaceae), Ephedra (Ephedraceae), cacti, and spiny bromeliads. The neotype was collected in a location described as “ dense, thorny vegetation that included quebracho, palo santo, palo borracho, and several species of cacti; however, a small, apparently natural grassy opening was also adjacent to the trap site. ”
