Two new species are segregated from the R. ovalifolia species complex: Rinorea chiribiquetensis from Chiribiquete National Park in the Colombian Amazon and Rinorea stevensii from the Orinoco River near the border of Colombia and Venezuela. Two new species are segregated from the Rinorea hirsuta species complex: Rinorea galeanoae-bernalii and Rinorea cogolloi, both from the eastern slopes of the Andean Central Cordillera along the mid-Magdalena River Valley in Colombia. From the widely distributed R. pubiflora species complex, we segregated one new species, Rinorea callejasii, from southeast Panama and the Chocó in Colombia. In addition to these five new taxa segregated from widely distributed species complexes, we discovered two previously unknown species with affinities to other Neotropical Rinorea. Rinorea aymardii is described from the Alto Orinoco-Casiquiare Biosphere Reserve in Venezuela and most closely resembles R. melanodonta from Colombia. Rinorea betancurii is segregated from R. macrocarpa and occurs in the Amazonian Regions of Colombia, Brazil, Peru and Venezuela. In this study, we provide descriptions, illustrations and distribution maps of the new species and make preliminary assessments of the risk of extinction using the IUCN Red List Categories and Criteria.
