Bayesian phylogenetic tree of partial cytochrome b sequences of 30 lineages of Haemoproteus parasites, 6 lineages of Plasmodium spp., and 1 Leucocytozoon sp. lineage used as an outgroup. Vertical bars (A-O) represent parasite species of the subgenera Parahaemoproteus (A), Haemoproteus (B), parasites of the genus Plasmodium (C), and the outgroup, a Leucocytozoon sp. parasite (O). Bold font indicates names of Haemoproteus species and their corresponding lineage for which megalomeronts were previously reported; note that these parasites are present throughout the phylogeny and have markedly different megalomeront morphology (see Discussion section for further explanation). The parasite lineage studied in this work is given in red font. Posterior probabilities are provided with symbols: triangles—0.7–0.8; squares—0.8–0.9; rounds—0.9–1. Lineage names are given according to MalAvi database (http://130.235.244.92/Malavi/, accessed on 28 September 2021), followed by their parasite species names and sequence GenBank accession numbers.
