This bat is known from limestone karst in northeastern Vietnam. The original description named it Aselliscus dongbacana; this entry uses the current Mammal Diversity Database spelling, Aselliscus dongbacanus.
The back is buffy brown to grayish brown and the underside is paler, nearly whitish. The upper edge of the noseleaf has three points, with small lateral leaflets along its sides.
The species is associated with limestone karst and was recorded using caves as roosts in both heavily degraded and relatively intact sites.
