The Amazonian sac-winged bat is a small South American emballonurid. Records are exceptionally sparse, leaving major gaps in its known range and roosting ecology.
The attachment of the wing membrane to the metatarsus is described as a feature distinguishing this species.
Its roosting habits remain unverified. A 2016 study of Amazonian bats found no published observations that could confirm roost behavior for this species.
An extinction-risk assessment has not been added yet.
