Area: Endemic to the Con Dao islands of Vietnam, with confirmed locations on Con Son, Hon Ba, Hon Bay Canh, Hon Cau, Tre Lon, Tre Nho, and Hon Tai.
Habitat: Cnemaspis boulengeri inhabits lowland forest habitats, rocky areas, caves, and granitic boulders. During the day, it can be found climbing on rocks and tree trunks, and at night it shelters in rock cracks and caves.
