Fig. 1 ML/BI phylogenetic tree based on SSU rDNA sequences of T. xiushanensis n. sp. and
the related species, adding the infection sites and hosts of Thelohanellus species
Numbers given at nodes of branches are bootstrap support values of BI/ML; the red triangles indicate the species in the present study; the numbers after
the species name represent the GenBank accession number; // is shortened to a half of the original length.
