The 1998 systematics study treats the Gambian slit-faced bat as a distinct species in West Africa; it is also recorded in several parts of Guinea-Bissau.
It is medium-sized within its family, with small ears, plain sepia fur on the back, a slightly paler underside, and dark brown wings.
A Guinea-Bissau survey found about 50 individuals sharing a small building as a roost; a female was also caught while active at night among cashew and mango trees.
An extinction-risk assessment has not been added yet.
