Haemoproteus parasites (Apicomplexa, Haemosporida) are widespread pathogens of birds, with a rich genetic (about 1900 lineages) and morphospecies (178 species) diversity. Nonetheless, their life cycles poorly understood. The exo-erythrocytic stages three majoris (widespread generalist parasite) lineages have been previously reported, each in different bird species. We aimed to further study com...
