Maximum likelihood (ML) phylogenetic tree based on ITS nuclear gene using RAxML. Codes of clones and a list of reference sequences are provided in the Additional file 1: Tables S1 and S3. More than 50% bootstrap support values are shown above the branches. The lineages (subclades) close to B. fatalis and B. hagmanni are marked in green and in purple, respectively. Colorful bands represent the classification of species, while black rectangles represent subgenera aggregation based on species
