Abstract
Based on findings of revisionary studies of Neotropical Rinorea, we propose several taxonomic novelties and clarifications in this study, including the description of three new species, a new combination, the placement of three species in synonymy, and updated descriptions of two poorly known species from South America. One of the new species, Rinoreaidarragae, is described from Mesoamerica and belongs to R.sect.Rinorea. The two other new species are from South America and are placed in R.sect.Pubiflorae: Rinoreacardenasii occurs in the region of the western edge of the Guiana Shield in Colombia, and Rinoreapabongonzaleziorum is from the Amazon Basin in Colombia and Venezuela. Rinorealindenianavar.fernandeziana is elevated to the rank of species, and Rinoreacordata, R.antioquiensis, and R.hymenosepala are synonymized under R.laurifolia, R.squamata, and R.ulmifolia, respectively. Finally, we provide updated descriptions of Rinoreadeflexa from Ecuador and Peru and Rinoreabicornuta from Colombia and Brazil. For the three new species, we provide descriptions, illustrations, distribution maps, and preliminary conservation assessments based on IUCN Red List categories and criteria.
