An inventory of the weevil fauna of Mona Island, Puerto Rico, is provided. Sixteen new records and 5-9 new species are reported, yielding a total of 28 species of Curculionoidea for the island. The distribution and natural history of each species are briefly reviewed. As many as nine species are endemics, whereas 15 species are shared with Puerto Rico which was the primary source region for Pliocene-Pleistocene colonization events. Mona Island's weevil fauna is depauperate and dominated by members of the Cossoninae, Anthonomini, Tychiini, Entiminae, and Scolytinae. The apparent underrepresentation of common Caribbean weevil lineages such as the Cryptorhynchinae suggests that subaerial land bridges during the Oligocene-Miocene period were important in facilitating their colonization of the main island of Puerto Rico.
