Locally common to uncommon, the species is found in primary and secondary forest in the mountains and in the lowlands. This species also inhabits caves, but is commonly found under tree buttresses or in rock crevices. It endemic and restricted to the Palawan Faunal Region. It has been recorded in the islands of Busuanga, Calauit, and Coron, and on the mainland at the Puerto Princesa Subterranean River National Park, and the forested areas of El Nido.
