This opossum is known from the Orinoco Delta of northeastern Venezuela. It is recorded in flooded evergreen forest and has a dark stripe along its brown back.
The back is brown and the underside cream-colored, with a dark band from the head to the base of the tail. Small pale spots sit above the eyes; the tail is furred over about one fifth of its length from the base.
The species is recorded in evergreen forests 15–25 m tall that are flooded permanently or seasonally.
