This short-tailed opossum occurs in French Guiana and northern Brazil. A Brazilian species guide records Amapá and Pará, while the Mammal Diversity Database gives French Guiana and northern Brazil.
It is small, with a tail about 70% of head-and-body length. Its short, soft fur is gray on the back, reddish on the sides, chin, and throat, and cream to gray on the underside.
The Brazilian species guide records it in Amazon forest. The cited account does not describe activity time or diet, so neither is inferred here.
