In the present study, we investigated the distribution of Kielmeyera (Calophyllaceae), a woody, typically wind-dispersed genus, with a high endemism rate in the Atlantic Forest. The 351 specimens analysed, representing 21 of 22 species of Kielmeyera from the Atlantic Forest, pointed to a complete dissimilarity between species composition in the southern (Rio de Janeiro state) and northern (Bahia state) portions of the forest. However, the Rio Doce valley in Espírito Santo state, rather than being a limit between these two portions, appear to represent a confluent area. The northern boundary of species from the southern portion is the São Mateus basin, whereas the southern boundary of species from the northern portion is at the Litorânea do Espírito Santo basin. Most specimens of Kielmeyera were collected in areas that currently are not remnants of original vegetation and that are not within any conservation unit, suggesting that an imminent loss of biodiversity is taking place. Studies comprising a broad range of functionally and phylogenetically distinct taxa make individual patterns of distribution obscure and overlook the conservation needs for specific groups. Therefore, our study on the distribution of Kielmeyera in the Atlantic forest highlights the importance of biogeographic analyses of less inclusive taxa of a flora.

The species is critically endangered and can be easily distinguished from other Kielmeyera species by the rusty coloration of the trunk and branches, orange-colored latex, and the occurrence in flooded areas. It differs from the other species of the section Prolifera by the leaves with secondary veins relatively more distant from each other and prominent on the abaxial surface. Diagnostic characters and the state of conservation of the new species are discussed, and an identification key for K. ferruginosa and related species from series Rupestres and Neglectae is provided.

Four genera and 21 species are recognized: Calophyllum (C. brasiliense), Caraipa (C. densifolia), Kielmeyera (18 species) and Mammea (M. americana), of which seven species are endemic to the state. Identification keys to genera and species, descriptions, taxonomic comments, illustrations and maps of geographic distribution of species in the state are presented.
