Thylamys pulchellus, known as the Dry Chaco fat-tailed opossum, is a species of opossum in the subfamily Didelphinae. The species is endemic to the Argentine portion of Gran Chaco. The species was also once considered to be a part of the common fat-tailed mouse opossum (Thylamys pusillus) but is now considered a different species based on morphological and genetic differences.[1][2][3]
