Bayesian phylogenetic analysis of cytb gene lineages (470 bp) of avian haemosporidian parasites, rooted with Leucocytozoon species lineage lSISKIN2. Posterior clade probabilities of > 0.60 were indicated. The branch lengths are drawn proportionally to the amount of change according to the substitution model applied. Key: dark grey area, species of subgenus Haemoproteus; light grey area, species of subgenus Parahaemoproteus; diamond, Haemoproteus spp. lineages derived from penguins in previous studies (see Table 2); circle, Haemoproteus spp. lineages derived from Larus sp. gulls in previous studies (see Table 2); red letters, lineage derived in this study
