A new species of Peter's tent-making bat, genus Uroderma (Chiroptera: Phyllostomidae), is described from Venezuela's Cordillera del Caribe and piedmonts of the Eastern Cordillera of the Colombian Andes. Cranial morphology of the new species approaches that of U. magnirostrum, with a notable enlargement of the nasals in the post-orbital region, giving the skull a flatter appearance in lateral profile than typical specimens of U. bilobatum. The new species of Uroderma can be distinguished easily from U. magnirostrum by several discrete skin and cranial characters. Taxonomic affinities among geographic variants of U. bilobatum were assessed through analyses of morphologic, karyotypic, and molecular variation. Although statistical support for well-defined groups was low in morphological assessments, four morphotypes were recognized based on geographic structure and previously reported karyotypic and molecular data. In addition to the newly recognized species, U. convexum Lyon 1902 is elevated to species status, and U. c. molaris is treated as a subspecies of U. convexum. Further, based on reciprocal monophyly of supported clades present in analyses of mitochondrial DNA data, assortment of karyotypes distinguished by three rearrangements, and reduced fitness in hybrids, U. davisi Baker and McDaniel 1972 is treated as a species. These taxonomic revisions result in a genus comprised of five species (U. bilobatum, U. convexum, U. davisi, U. magnirostrum, and U. bakeri sp. nov.)
