Abstract

During recent field expeditions to forest remnants in the state of Rio de Janeiro, Brazil, a distinctive Eugenia species was collected and is here proposed as a new taxon. This study is based on literature and herbarium and field collections. The conservation status was assessed based on the IUCN Red List categories and criteria. The map of occurrence records was built through QGIS Desktop software using shapefiles from open-source databases. The newly described Eugenia bragae is currently known only from the Atlantic Forest in the state of Rio de Janeiro, Brazil. It is here assigned to Eugenia subg. Pseudeugenia and compared with E. culicina. We also provide a table comparing the new taxon with E. altissima and E. laruotteana.

Durante recentes expedições de campo em remanescentes florestais no Estado do Rio de Janeiro, Brasil, uma espécie distinta de Eugenia foi coletada e é aqui proposta como um novo táxon para a ciência. Este estudo é baINEAdo em revisão de literatura e coleções de campo e herbário. O status de conservação foi analisado com base em IUCN Red List Categories and Criteria. O mapa de pontos de ocorrência foi construído por meio do software QGIS Desktop usando shapefiles de bancos de dados abertos. A nova espécie aqui descrita, Eugenia bragae, é atualmente conhecida apenas na Mata Atlântica no Estado do Rio de Janeiro, Brasil. É aqui atribuída a Eugenia subg. Pseudeugenia e comparada com E. culicina. Também fornecemos uma tabela comparando essas espécies com outros dois taxa semelhantes, E. altissima e E. laruotteana.
