Summary
This study proposes a new species of Eugenia sect. Phyllocalyx from Atlantic Forest remnants in the Brazilian state of Rio de Janeiro. The new taxon, Eugenia guapiassuana, is proposed based on literature survey, examination of herbarium material and field work. We herein provide a morphological description, including comments on fruit taste, along with information on distribution, habitat, phenology, vernacular name, taxonomy and conservation status. Figures showing fresh and dry material and a map of the occurrence records are also presented. Eugenia guapiassuana is morphologically similar to E. involucrata and E. superba, and these species are contrasted in the discussion. Following an assessment, the conservation status of Eugenia guapiassuana is provisionally determined as Critically Endangered [CR B2ab(iii)].
