ResumoThe loricariid genus Pogonopoma Regan, 1904, is revised and expanded to include Pogonopomoides parahybae and a new species, Pogonopoma obscurum, from the upper rio Uruguai, southern Brazil. The new species can be distinguished from its congeners by having eight to 11 branched dorsal fin rays, versus seven in the remaining species. The phylogenetic placement and geographic distribution of the new species are evaluated and discussed. An identification key for the genera of the Rhinelepis group of the subfamily Hypostominae and for the species of Pogonopoma is provided.
