The Biak Leaf-nosed Bat is a member of the leaf-nosed bat family. A 1989 survey recorded it on islands beyond Biak, including sites in the Maluku region and western New Guinea.
A 2007 comparative paper says that H. papua usually, but not invariably, has a small third supplementary leaflet on the noseleaf.
The Wallacea paper reports specimens from caves near the Amaru Lakes, a shallow cave in primary forest on Bacan, and forest near Mount Gamkunora on Halmahera. These are collection settings, not a study of preferred roosts or habitat.
An extinction-risk assessment has not been added yet.
