Abstract

The Haemosporida order is a well-supported clade of heteroxenous parasites transmitted by dipteran insects and frequently found parasitizing wild birds. These parasites have already been reported in all zoogeographic regions of the world, except for Antarctica. One of the potential hosts of haemosporidians is the Cracidae family, which includes approximately 50 species, 22 of which are present in Brazil, classified within nine genera. Data on haemosporidian infecting individuals of the Cracidae family is scarce, with only three Haemoproteus species being recorded in this group of birds. We found Haemoproteus spp. infection in all Penelope obscura bronzina analyzed. Among the parasites found, we observed two lineages of Haemoproteus (PENOBS02 and PENOBS03), which were characterized by morphological, molecular and phylogenetic approaches. The morphological data on cracid haemosporidian parasites, together with our phylogenetic results, allows discussions on the taxonomy of the Haemoproteus parasites that infect birds of the Cracidae family.

Keywords: Atlantic forest; Avian Haemosporidia; Haemoproteus ortalidum; Haemoproteus paraortalidum; Penelope obscura bronzina.
