SUMMARY:

The Atlantic Rain Forest is one of the great hotspots of biodiversity and species endemism in the world. One of the factors responsible for generating so much diversity is the relief. The mountains offer very different environmental conditions in relation to the surrounding areas, in addition to strong geographic isolation, resulting in high rates of endemism. Studies on biodiversity in mountains of the Atlantic Rain Forest have already revealed the presence of several species, but the diversity of avian hemosporidia in the mountains in these places is still unknown. Thus, the objective of the present study was to investigate the diversity of Plasmodium in montane environments of the Brazilian Atlantic Forest using morphological, molecular, and phylogenetic techniques. 621 birds were sampled at altitudes from 700 to 2500 meters above sea level. The prevalence of Plasmodium sp. recorded was 4.25% (26/521). In a bird of the species Rhopias gularis sampled in the mountains of the Itatiaia National Park, it was possible to characterize and describe a new species of avian malaria parasite, Plasmodium erickdaemoni n. sp.. Through the results obtained, we enriched our knowledge about the global diversity of Plasmodium and the species of the Atlantic Rain Forest, a highly threatened biome that has the potential to harbour many species of avian malaria parasites not yet known to science, given its large biodiversity and the little sampling already carried out. The data presented here suggest a considerable effect of relief on the diversity and endemism of Plasmodium in South America, since the new described species occurs in montane environments of the Andes and the Atlantic Rain Forest.
