The Guadeloupe Serotine is a large bat known only from Guadeloupe. It is reported to hunt insects around humid forest and wetland habitats.
Its fur is brown above and paler below. The profile also describes it as large-bodied, with a swollen nose and broad wings.
It is insectivorous and hunts beetles and termites in humid forests, wetlands, and the habitats between them. Tree roosts are suspected; it has also been observed in an attic.
An extinction-risk assessment has not been added yet.
