Three new species of flea beetles (Coleoptera: Chrysomelidae: Galerucinae: Alticini) from moss cushions from Puerto Rico are described: Borinken toronegro Konstantinov and Linzmeier and Kiskeya segar-rai Konstantinov and Linzmeier from the Toro Negro mountain region and Kiskeya micheliorum Konstantinov and Linzmeier from the Maricao mountains. New species are compared morphologically with already known species from the same genera. In addition, to determine the similarities between moss inhabiting flea beetles, we sequenced the Cytochrome oxidase I barcode region of larval and adult specimens. In all cases, the distances between species are well outside the 2% species-limit cutoff typically used as an indicator of different species.
