We present results from several recent herpetological surveys in the Romblon Island Group (RIG), Romblon
Province, central Philippines. Together with a summary of historical museum records, our data document the occurrence
of 55 species of amphibians and reptiles in this small island group. Until the present effort, and despite past studies,
herpetological diversity of the RIG and their biogeographical affinities has remained poorly understood. We report on
observations of evolutionarily distinct amphibian species, including conspicuous, previously known, endemics like the
forest frogs Platymantis lawtoni and P. levigatus and two additional suspected undescribed species of Platymantis. Moderate
levels of reptile endemism prevail on these islands, including taxa like the karst forest gecko species Gekko romblon and the
newly discovered species G. coi. Although relatively small and less diverse than the surrounding landmasses, the islands
of Romblon Province contain remarkable levels of endemism when considered as percentage of the total fauna or per unit
landmass area
