Fig. 6. Bayesian Inference tree (A) based on partial (478 bp) cytb sequences of Haemoproteus angustus n. sp. (lineage hCWT7) and the 20 closest related Haemoproteus lineages. Bayesian posterior probabilities and Maximum Likelihood bootstrap values were indicated above and below nodes, respectively. For each lineage, representative GenBank accession numbers and MalAvi lineage codes (if available) are indicated as well as the most common bird host. The scale bar indicates the expected mean number of substitutions per site according to the model of sequence evolution applied. Images B and C show the Median-Joining DNA haplotype network of partial (478 bp) cytb sequences of H. angustus hCWT7 and the 20 closest related Haemoproteus lineages. The upper image (B) shows the host distribution, and the lower image (C) depicts the geographic distribution according to the United Nations geoscheme. Each circle represents a unique haplotype/lineage. The frequency of each lineage is indicated for all haplotypes with more than one record and roughly corresponds to the size of circles. Bars on branches indicate the number of substitutions between two haplotypes. Small white circles represent median vectors, which are hypothetical (often ancestral or unsampled) sequences required to connect existing haplotypes with maximum parsimony.

Note: the markedly attenuated gametocytes of the new species (A–D), which are not present in other Haemoproteus parasites (E–X); the fully grown gametocytes of H. belopolskyi (F, H) and H. parabelopolskyi (J, L) are bigger than those of H. angustus n. sp.; the pigment granules are predominantly roundish and small in H. pallidulus (M–P); the fully grown gametocytes are small and do not reach poles of infected erythrocytes in H. homogeneae (R, T); the erythrocyte nuclei are displaced laterally by H. majoris (V, X) – all these feature are not characteristic of H. angustus sp. nov.

Data from: The polyphyly of Plasmodium: comprehensive phylogenetic analyses of the malaria parasites (order Haemosporida) reveal widespread taxonomic conflict
The evolutionary relationships among the apicomplexan blood pathogens known as the malaria parasites (order Haemosporida), some of which infect nearly 200 million humans each year, has remained a vexing phylogenetic problem due to limitations in taxon sampling, character sampling, and the extreme nucleotide base composition biases that are characteristic of this clade. Previous phylogenetic work on the malaria parasites has often lacked sufficient representation of the broad taxonomic diversity within the Haemosporida or the multi-locus sequence data needed to resolve deep evolutionary relationships, rendering our understanding of haemosporidian life history evolution and the origin of the human malaria parasites incomplete. Here we present the most comprehensive phylogenetic analysis of the malaria parasites conducted to date, using samples from a broad diversity of vertebrate hosts that includes numerous enigmatic and poorly known haemosporidian lineages in addition to genome-wide multi-locus sequence data. We find that if base composition differences were corrected for during phylogenetic analysis, we recovered a well-supported topology indicating that the evolutionary history of the malaria parasites was characterized by a complex series of transitions in life history strategies and host usage. Notably we find that Plasmodium, the malaria parasite genus that includes the species of human medical concern, is polyphyletic with the life history traits characteristic of this genus having evolved in a dynamic manner across the phylogeny. We find support for multiple instances of gain and loss of asexual proliferation in host blood cells and production of hemozoin pigment, two traits that have been used for taxonomic classification as well as considered to be important factors for parasite virulence and used as drug targets. Lastly, our analysis illustrates the need for a widespread reassessment of malaria parasite taxonomy.
