There are, therefore, 36 species identified and confirmed to exist in Palawan so far but there are suggestions there could be more extant species that could not be sampled due to their foraging, roosting or flying habits. It is also possible that misidentification of some of these species were made. Further studies are required to confirm all these findings and proposition on the existence of some species.
Nine of these species are known to occur in the world-renowned Puerto Princesa Subterranean River National Park.
