Bayesian inference tree of partial cytochrome b gene sequences of 92 Leucocytozoon lineages and sequences linked to a morphospecies. Two lineages (Haemoproteus columbae hHAECOL01 and Leucocytozoon (Akiba) caullery lGALLUS05) were used as the outgroup. Parasite lineages were presented as they appear in the MalAvi database. Two clades were highlighted according to the morphotypes some of the lineages were linked to, being L. majoris (A) and L. fringillinarum (B). Bold font indicates the lineages obtained in this study. The new lineage is indicated with an asterisk. All the posterior probabilities ≥ 0.7 were provided with a black dot. GenBank accession numbers of the sequences used in the phylogeny are given in Supplementary Table S1.
